The fitness industry thrives on myths. Why? Because myths sell supplements, programs, and magical solutions. The truth—that building muscle requires consistent training, adequate protein, and patience—doesn't sell as well.

This guide destroys the 15 most damaging muscle building myths that waste people's time and money. Every myth is debunked with actual scientific research, not bro-science or gym folklore.


What makes this different: No clickbait. No selling you supplements. Just peer-reviewed research and honest truths about what actually builds muscle.


By the end, you'll know exactly what works, what doesn't, and why most "common knowledge" about muscle building is completely wrong.

The 15 Biggest Muscle Building Myths

Training Myths

credits: Bava87

Myth #1: You Need to Feel Sore to Build Muscle

The Myth: "No pain, no gain." If you're not sore the next day, you didn't work hard enough.

The Truth: Soreness (DOMS - Delayed Onset Muscle Soreness) is NOT an indicator of muscle growth.

The Science:

  • Soreness is caused by eccentric muscle damage and inflammation

  • Studies show muscle can grow significantly without soreness

  • Advanced lifters rarely get sore but continue building muscle

  • Soreness typically decreases as your body adapts (doesn't mean growth stops)

Research: A 2019 study in Sports Medicine found zero correlation between muscle soreness and hypertrophy (muscle growth). You can build muscle without ever being sore.

What actually matters:

  • Progressive overload (lifting more over time)

  • Training volume (sets x reps x weight)

  • Adequate protein intake

  • Sufficient recovery

Bottom line: Soreness is a sign you did something new or increased intensity. It's not required for growth.


Myth #2: You Must Train to Failure Every Set

The Myth: Every set should be taken to absolute muscular failure (can't do another rep) for maximum growth.

The Truth: Training close to failure (1-3 reps shy) builds just as much muscle with less fatigue and injury risk.

The Science:

  • Studies show sets stopped 1-3 reps before failure produce similar hypertrophy

  • Training to failure every set dramatically increases recovery time

  • Constantly training to failure leads to overtraining and injury

  • Central nervous system fatigue accumulates faster

Research: A 2021 meta-analysis in Journal of Strength and Conditioning Research found no significant difference in muscle growth between training to failure vs. stopping 1-2 reps short.

When to use failure:

  • Last set of an exercise (occasionally)

  • Isolation exercises (safer than compounds)

  • Experienced lifters who understand their limits

When NOT to:

  • Every set

  • Heavy compound lifts (squat, deadlift, bench)

  • Multiple times per week consistently


Myth #3: You Need to Constantly Change Exercises for "Muscle Confusion"

The Myth: Muscles adapt quickly, so you must constantly change exercises every workout to "confuse" them.

The Truth: Muscles don't get "confused." Progressive overload with consistent exercises builds more muscle than constant variation.


The Science:

  • Muscles respond to mechanical tension, not variety

  • Constantly changing exercises prevents you from tracking progress

  • Mastering movement patterns allows heavier loads (better stimulus)

  • Studies show exercise variation has minimal impact on hypertrophy


Research: 2018 study in Medicine & Science in Sports & Exercise found no difference in muscle growth between groups using consistent vs. varied exercises.

What actually works:

  • Stick with 4-6 core exercises for 8-12 weeks

  • Master the movement patterns

  • Progressively increase weight/reps

  • Only change when truly plateaued (not weekly)

Smart variation: Change rep ranges, tempo, or rest periods—not exercises constantly.


Myth #4: High Reps for Definition, Low Reps for Mass

The Myth: Want to "tone" and get defined? Do high reps (15-20+). Want to get big? Do low reps (1-5).

The Truth: Rep ranges from 6-30+ all build similar amounts of muscle when taken close to failure. "Toning" doesn't exist—you build muscle or lose fat.

The Science:

  • "Toning" is muscle visibility (low body fat + developed muscle)

  • High reps build muscle just like low reps (if volume is equated)

  • Research shows effective range: 6-30 reps per set

  • Different rep ranges emphasize different adaptations (strength vs. endurance), but all build muscle

Research: 2017 meta-analysis by Brad Schoenfeld found similar muscle growth across rep ranges from 6-35 reps when sets are taken near failure.

Optimal approach:

  • Use multiple rep ranges (variety for complete development)

  • 6-8 reps: Compound movements (squat, bench, deadlift)

  • 8-12 reps: Main hypertrophy work (most exercises)

  • 12-20 reps: Isolation and metabolic stress

  • 20+ reps: Finishers, endurance, injury-prone exercises

Bottom line: Pick rep ranges based on exercise and goals, but all ranges build muscle effectively.


Myth #5: You Must Feel the "Pump" to Build Muscle

The Myth: If you don't get a massive pump during your workout, you're not building muscle.

The Truth: The pump feels good and indicates blood flow, but it's not necessary for growth.

The Science:

  • Pump = temporary cell swelling from metabolite accumulation

  • It's ONE mechanism of hypertrophy (cell swelling), but not the only one

  • Heavy strength training builds muscle without much pump

  • Some people are "non-responders" who don't get pumps easily

What actually drives growth:

  1. Mechanical tension (lifting heavy loads)

  2. Metabolic stress (pump, burn, lactate)

  3. Muscle damage (micro-tears from training)

All three contribute, but mechanical tension is most important.

Bottom line: Chase progressive overload, not the pump. The pump is a bonus, not a requirement.


Nutrition Myths

Myth #6: You Need 1g Protein Per Pound of Bodyweight

The Myth: You MUST eat 1g of protein per pound of bodyweight (220g for a 220lb person) to build muscle.

The Truth: 0.7-1g per pound (1.6-2.2g per kg) is sufficient. More doesn't build more muscle.

The Science:

  • Studies consistently show 0.7-0.8g per lb of bodyweight maximizes muscle protein synthesis

  • Going beyond 1g per lb provides no additional benefit

  • Excess protein is converted to glucose or excreted (expensive pee)

Research: 2018 meta-analysis in British Journal of Sports Medicine found no benefit above 1.6g per kg (0.73g per lb) for muscle growth.

Optimal intake:

  • Muscle building: 0.7-1g per lb (1.6-2.2g per kg)

  • Cutting (fat loss): 1g per lb (helps preserve muscle in deficit)

  • Average person: 0.7-0.8g per lb is plenty

Example: 180lb person needs 126-144g protein daily (not 180g).

Bottom line: More protein ≠ more muscle after a certain point. Eat adequate amounts, save your money.


Myth #7: You Have a 30-Minute "Anabolic Window" After Training

The Myth: You MUST consume protein within 30 minutes post-workout or you'll lose all your gains.

The Truth: The "anabolic window" lasts 24+ hours. Timing matters far less than total daily protein.

The Science:

  • Muscle protein synthesis stays elevated 24-48 hours after training

  • Total daily protein intake matters more than precise timing

  • Pre-workout protein extends the anabolic window through your workout

  • Only critical if you trained fasted (no food 4-6 hours before)

Research: 2013 study in Journal of the International Society of Sports Nutrition found total daily protein intake was the primary driver of muscle growth, not timing.

When timing matters:

  • Training fasted (empty stomach) → protein within 1-2 hours helps

  • Multiple daily sessions → timing becomes more important

  • Very long workouts (2+ hours) → intra-workout nutrition helps

For most people:

  • Eat protein 2-3 hours before training

  • Eat protein 2-3 hours after training

  • Hit your daily target (0.7-1g per lb)

  • Timing is a 5% detail, not a dealbreaker


Myth #8: Carbs Make You Fat / You Need Carbs to Build Muscle

The Myth: Two opposite myths exist:

  • "Carbs make you fat—go low-carb/keto"

  • "You NEED carbs to build muscle"

The Truth: Carbs don't inherently make you fat. Caloric surplus does. You CAN build muscle on low-carb, but carbs help performance.

The Science:

  • Fat gain/loss is determined by calories (energy balance), not carbs

  • Carbs improve training performance (glycogen = fuel for high-intensity work)

  • You can build muscle on keto/low-carb, but most people perform better with carbs

  • Protein and total calories matter more than carb intake

Research: 2014 study in JAMA comparing low-carb vs. low-fat diets found no difference in weight loss or body composition when calories and protein were matched.

Optimal approach:

  • Prioritize protein first (0.7-1g per lb)

  • Fill remaining calories with carbs and fats based on preference

  • Most people perform best with: 40-50% carbs, 25-35% protein, 20-30% fat

  • Athletes/hard trainers: higher carbs (50-60%)

  • Sedentary/prefer fats: lower carbs (20-30%)

Bottom line: Carbs are a tool for performance, not a magic ingredient or poison.


Myth #9: Eating Late at Night Causes Fat Gain

The Myth: Don't eat carbs or any food after 6-7 PM—your metabolism slows down and you'll store everything as fat.

The Truth: Meal timing doesn't matter for body composition. Total daily calories matter.

The Science:

  • Your body doesn't have an "off switch" at night

  • Late-night eating only causes fat gain if it pushes you into caloric surplus

  • Some studies show eating before bed may help muscle recovery

  • Many successful athletes eat large meals late at night

Research: 2011 study in Obesity found no difference in fat loss between groups eating most calories in the morning vs. evening when total intake was matched.

Real factors that matter:

  1. Total daily calories

  2. Total daily protein

  3. Training consistency

  4. Sleep quality (late eating may disrupt sleep for some)

Bottom line: Eat when it fits your schedule and preferences. Total intake matters, not timing.


Recovery Myths


Myth #10: More Training = More Muscle

The Myth: If 3 days per week is good, 6 days must be better. Training every day builds muscle faster.

The Truth: Muscle grows during recovery, not during training. Overtraining kills progress.

The Science:

  • Training creates the stimulus for growth

  • Recovery/sleep is when actual growth happens

  • More volume helps to a point, then harms progress

  • Studies show optimal frequency: 2-4x per muscle per week

Research: 2019 study in Sports Medicine found diminishing returns above 10-20 sets per muscle per week for most people.

Signs of overtraining:

  • Strength decreases instead of increases

  • Constant fatigue/poor sleep

  • Elevated resting heart rate

  • Loss of motivation

  • Increased injury rates

  • Mood disturbances

Optimal training frequency:

  • Beginners: 3-4 days per week (full body)

  • Intermediate: 4-5 days per week (upper/lower or push/pull/legs)

  • Advanced: 5-6 days per week (body part splits)

Critical: Each muscle needs 48-72 hours recovery between intense sessions.


Myth #11: You Need 8+ Hours of Sleep or You Won't Build Muscle

The Myth: If you don't get 8+ hours of sleep, you're wasting your workouts.

The Truth: Sleep is crucial, but 6-8 hours is sufficient for most people. Quality matters as much as quantity.

The Science:

  • Sleep is when growth hormone peaks and recovery happens

  • Chronic sleep deprivation (less than 6 hours) definitely impairs gains

  • 7-9 hours is optimal, but 6-7 hours is workable

  • Sleep quality (deep sleep) matters more than total hours

Research: 2018 study found testosterone levels drop 10-15% with sleep under 5 hours, but 6-7 hours showed minimal impact.

Realistic advice:

  • Aim for 7-9 hours (ideal)

  • Minimum: 6 hours (still productive, not optimal)

  • Below 6 hours consistently: muscle growth significantly impaired

  • Focus on sleep quality: dark room, cool temp, consistent schedule

If you can't get 8 hours:

  • Prioritize deep sleep (first 3-4 hours most important)

  • Nap 20-30 minutes if possible

  • Manage stress (impairs recovery as much as poor sleep)


Supplement Myths





Myth #12: You Need Supplements to Build Muscle

The Myth: Protein powder, pre-workout, BCAAs, and dozens of supplements are necessary for muscle growth.

The Truth: 99% of muscle building comes from training, nutrition, and sleep. Supplements are 1% details.

The Science:

  • Only 3 supplements have strong evidence: protein powder, creatine, caffeine

  • Everything else is either ineffective or provides minimal benefit

  • You can build an incredible physique with zero supplements

  • Supplements are called "supplements" because they supplement a proper diet

Research: Multiple meta-analyses show most supplements have zero or negligible effect on muscle growth beyond placebo.

Actually useful supplements:

  1. Protein powder (convenience, not magic—same as food protein)

  2. Creatine monohydrate (5g daily, increases strength 5-15%)

  3. Caffeine (pre-workout, improves performance)

  4. Vitamin D (if deficient)

  5. Omega-3s (for general health)

Supplements that don't work:

  • BCAAs (if eating adequate protein)

  • Fat burners (mostly caffeine + placebo)

  • Testosterone boosters (legal ones don't work)

  • Most pre-workouts (overpriced caffeine)

Bottom line: Master training and nutrition first. Supplements are optional icing on the cake.


Myth #13: Creatine Causes Kidney Damage and Makes You Bloated

The Myth: Creatine is dangerous for your kidneys and makes you look bloated/puffy.

The Truth: Creatine is one of the most researched supplements with decades of safety data. It's safe and effective.

The Science:

  • 1000+ studies over 30+ years show creatine is safe for healthy individuals

  • No evidence of kidney damage in people with healthy kidneys

  • "Bloating" is minimal (1-2 lbs water in muscles, not under skin)

  • Creatine increases strength, power, and muscle mass by 5-15%

Research: 2017 position stand by International Society of Sports Nutrition concluded creatine monohydrate is safe and effective with no adverse effects in healthy people.

Actual effects:

  • Increases intramuscular water (inside muscle cells—good)

  • Does NOT cause subcutaneous water retention (bloating)

  • Improves performance in high-intensity exercise

  • May have cognitive benefits

Dosing:

  • 5g daily (timing doesn't matter)

  • No loading phase needed (it's optional, not required)

  • Mix with water, take with meals

  • Cheapest and most effective: creatine monohydrate

Who should avoid: People with pre-existing kidney disease (consult doctor).


Myth #14: Natural vs. Synthetic Protein: Natural is Better

The Myth: You must eat "clean" whole food protein. Protein powder is inferior or unhealthy.

The Truth: Your body can't tell the difference. Whey protein is digested identically to chicken protein.

The Science:

  • Protein is protein—your body breaks it down to amino acids

  • Whey protein has same bioavailability as meat/eggs

  • Studies show no difference in muscle growth between food and powder

  • Protein powder is just convenient, not superior or inferior

Research: 2018 study comparing whey vs. whole food protein found identical muscle protein synthesis and growth.

When to use protein powder:

  • Convenience (easier than cooking)

  • Hitting protein target when appetite is low

  • Post-workout if you prefer liquids

  • Traveling or busy schedule

When whole food is better:

  • More satiating (keeps you full longer)

  • Contains micronutrients (vitamins, minerals)

  • More affordable (often)

  • Tastes better for some

Ideal approach: 80% whole food protein, 20% powder for convenience.


Genetics and Limits

Myth #15: Genetics Don't Matter / Genetics Determine Everything

The Myth: Two opposite myths:

  • "Anyone can look like a bodybuilder with hard work"

  • "I have bad genetics so I can't build muscle"

The Truth: Genetics matter significantly, but everyone can build substantial muscle with proper training.

The Science:

  • Genetics determine:

    • Muscle fiber type distribution (fast-twitch vs. slow-twitch)

    • Muscle belly length and insertion points

    • Hormone levels (testosterone, growth hormone)

    • Recovery ability

    • Response to training (some gain 2x more muscle than others on same program)

  • Studies show 10-20x variation in muscle growth between individuals on identical programs

Research: 2005 study in Medicine & Science in Sports & Exercise found muscle growth ranged from 0% to 50%+ in 12 weeks on the same training program.

What this means:

  • Everyone CAN build muscle (it's biological)

  • Not everyone can be a pro bodybuilder (genetic lottery)

  • Your genetics determine your ceiling, not your potential for improvement

  • Comparing yourself to others is pointless (different starting points)

The reality:

  • Poor responder: Gains 5-10 lbs muscle in first year

  • Average responder: Gains 15-25 lbs muscle in first year

  • Excellent responder: Gains 25-40+ lbs muscle in first year

Bottom line: Work with your genetics, don't fight them. You may not become Mr. Olympia, but you can build an impressive physique regardless of genetics.

FAQ

1. If most of what I believed was wrong, where do I start?

Answer: Focus on the proven fundamentals:

Training:

  • Progressive overload (lift more over time)

  • 10-20 sets per muscle per week

  • 6-30 rep range (all work)

  • Train each muscle 2-3x per week

  • Don't train to failure every set

Nutrition:

  • Caloric surplus (200-500 cal/day above maintenance)

  • 0.7-1g protein per lb bodyweight

  • Eat mostly whole foods

  • Timing matters very little

Recovery:

  • 6-9 hours sleep nightly

  • 48-72 hours between hitting same muscle hard

  • Manage stress

That's it. Master these basics before worrying about details.

2. How do I know if information is science-based or bro-science?

Answer: Ask these questions:

Red flags (bro-science):

  • "This ONE trick will..."

  • No references to studies

  • Promises fast results (30 days to massive)

  • Sells expensive supplements/programs

  • Uses lots of jargon to sound smart

Green flags (science-based):

  • References actual studies

  • Acknowledges individual variation

  • Honest about realistic timelines

  • Doesn't claim one method is "only" way

  • Admits when evidence is unclear

Trusted sources:

  • Jeff Nippard (science-based, references studies)

  • Eric Helms (PhD, researcher)

  • Brad Schoenfeld (PhD, hypertrophy expert)

  • Renaissance Periodization (Dr. Mike Israetel)

  • Stronger By Science (Greg Nuckols)

3. How long does it actually take to build noticeable muscle?

Answer: Realistic timeline:

Months 1-3:

  • Beginners: Noticeable strength gains (neural adaptations)

  • 2-5 lbs muscle (some water weight included)

  • Clothes fit slightly tighter

Months 4-6:

  • 5-12 lbs total muscle gain

  • Visible definition and size increase

  • Others start noticing

Months 7-12 (Year 1):

  • 15-25 lbs muscle gain (average)

  • Substantial transformation

  • Clear before/after difference

Year 2:

  • 10-15 lbs additional muscle

  • Slower but steady progress

Year 3+:

  • 5-10 lbs per year

  • Diminishing returns (approaching genetic potential)

Bottom line: First 6 months show clear progress. First year produces dramatic transformation. After that, gains slow significantly.

4. Can I build muscle in a caloric deficit (while losing fat)?

Answer: Yes, but it's limited:

Who can build muscle in a deficit:

  • Complete beginners (newbie gains)

  • People returning from long layoff (muscle memory)

  • Overweight individuals (plenty of stored energy)

Requirements:

  • High protein (1g per lb bodyweight)

  • Resistance training

  • Small deficit (300-500 calories)

  • Adequate sleep

Reality:

  • Rate of muscle gain is much slower than in surplus

  • Eventually you'll need a surplus to continue growing

  • Advanced lifters can't build muscle in deficit

Optimal approach:

  • Bulk: Build muscle in small surplus (200-500 cal/day)

  • Cut: Maintain muscle in moderate deficit (500 cal/day)

  • Repeat cycles

5. Do I need to count calories and macros?

Answer: Depends on your goals and personality:

When tracking helps:

  • Not making progress (need data to adjust)

  • Preparing for competition/photo shoot

  • Enjoy data and tracking

  • Have specific body composition goals

When tracking isn't necessary:

  • Making consistent progress without it

  • Causes obsessive behaviors

  • You eat intuitively and it works

  • Recreational fitness goals

Middle ground approach:

  • Track for 2-4 weeks to learn portion sizes

  • Stop tracking but use that knowledge

  • Only track again if progress stalls

Bottom line: Tracking is a tool, not a requirement. Use it if it helps, skip it if it doesn't.


6. How important is progressive overload really?

Answer: It's THE most important training principle.

Why:

  • Muscles adapt to stress

  • Once adapted, they stop growing

  • Progressive overload provides continued stimulus

  • All successful programs use progressive overload

Forms of progressive overload:

  1. Add weight (most common)

  2. Add reps

  3. Add sets

  4. Increase frequency (train muscle more often)

  5. Slow down tempo

  6. Reduce rest periods

  7. Improve form/range of motion

Example progression:

  • Week 1: Bench 135 lbs x 8 reps x 3 sets

  • Week 3: Bench 135 lbs x 10 reps x 3 sets (added reps)

  • Week 5: Bench 145 lbs x 8 reps x 3 sets (added weight)

  • Week 7: Bench 145 lbs x 10 reps x 3 sets (added reps again)

Without progressive overload: You'll maintain but not build muscle.

7. Is fasted cardio better for fat loss?

Answer: No, total daily caloric deficit matters, not fasted vs. fed state.

The science:

  • Fasted cardio burns more fat during exercise

  • BUT you burn less fat the rest of the day (body compensates)

  • 24-hour fat oxidation is identical between fasted and fed cardio when calories are matched

Research: Multiple studies show no difference in fat loss between fasted and fed cardio.

When fasted cardio makes sense:

  • Personal preference (some feel better fasted)

  • Scheduling convenience

  • You enjoy it

When it's worse:

  • Performance suffers (most people)

  • Muscle loss risk increases slightly

  • Makes you ravenously hungry later

Bottom line: Do cardio in whatever state allows best performance and adherence.

8. How many rest days do I need per week?

Answer: At least 1-2 full rest days, but "rest" doesn't mean complete inactivity.

Full rest days (no resistance training):

  • Beginners: 3-4 per week

  • Intermediate: 2-3 per week

  • Advanced: 1-2 per week

Active recovery on "rest" days:

  • Walking (30-60 minutes)

  • Light yoga/stretching

  • Swimming (easy pace)

  • Mobility work

Why rest matters:

  • Central nervous system recovery

  • Hormone regulation (testosterone, cortisol)

  • Psychological break (motivation)

  • Injury prevention

Signs you need more rest:

  • Strength decreasing

  • Chronic fatigue

  • Elevated resting heart rate

  • Motivation loss

  • Sleep disturbances

9. Can older people (40+, 50+, 60+) still build muscle effectively?

Answer: Yes! Older adults can build significant muscle, just slower than younger people.

The science:

  • Muscle protein synthesis decreases with age but still responds to training

  • Studies show people in their 60s-80s can build substantial muscle

  • It takes longer and requires more attention to recovery

Keys for older adults:

  • Higher protein intake (1g per lb recommended)

  • Longer warm-ups (joint preparation)

  • Prioritize form over heavy weight

  • More rest between sessions (72+ hours for same muscle)

  • Focus on compound movements

  • Creatine supplementation helps more at older ages

Realistic expectations:

  • 40s: Similar gains to 20s-30s

  • 50s: 70-80% of younger gains

  • 60s+: 50-70% of younger gains

Bottom line: It's never too late to start. You won't build muscle as fast as a 20-year-old, but you'll still make impressive progress.

10. How do I know if I'm a "hardgainer" or just not eating enough?

Answer: 99% of "hardgainers" simply aren't eating enough calories.

Common hardgainer mistakes:

  • Overestimating food intake (not tracking accurately)

  • High metabolism/activity level not accounted for

  • Skipping meals regularly

  • Not eating calorie-dense foods

The math test:

  • Track everything you eat for 7 days (measure/weigh)

  • Calculate average daily calories

  • If under 15-16 calories per lb bodyweight, you're undereating

Example: 150 lb "hardgainer"

  • Maintenance: ~2,250 calories

  • Needs for growth: 2,500-2,750 calories

  • Most are eating: 1,800-2,000 calories (way too low)

True hardgainer (rare):

  • Eats 18-20 calories per lb bodyweight

  • Still not gaining weight

  • Likely has hyperthyroidism or absorption issues

  • Needs medical evaluation

Solution for most:

  • Eat 16-18 calories per lb bodyweight

  • High-calorie foods (nuts, oils, dried fruit, smoothies)

  • Liquid calories easier than solid

  • Track consistently for 4 weeks


Conclusion

Most muscle building "knowledge" is mythology passed down through gym culture, not science. This guide destroyed the 15 most damaging myths that waste your time and money.


The Simple Truth About Building Muscle:

Training: ✅ Progressive overload (add weight/reps over time)✅ 10-20 sets per muscle per week✅ Train each muscle 2-3x per week✅ Stop 1-3 reps before failure (most sets)✅ Use 6-30 rep range (all work)

Nutrition: ✅ Caloric surplus (200-500 cal/day)✅ 0.7-1g protein per lb bodyweight✅ Total daily intake matters most (not timing)✅ Eat when convenient for you

Recovery: ✅ 6-9 hours sleep nightly✅ 1-2 full rest days per week✅ 48-72 hours between hitting same muscle✅ Manage stress

Supplements (Optional): ✅ Protein powder (convenience only)✅ Creatine (5g daily)✅ Caffeine (pre-workout)✅ Everything else is unnecessary


What to Ignore:

❌ Muscle confusion❌ Anabolic window urgency❌ Training to failure every set❌ Soreness as a requirement❌ Perfect meal timing❌ Expensive supplements❌ "Secret" methods

The reality: Building muscle is simple (not easy). It requires consistency with basic principles for months and years, not magic tricks or shortcuts.

Stop chasing myths. Start following science. Your gains will thank you.
