I'll always remember the first time I caught myself on tape squatting. Two years I'd thought I had perfect form, and it wasn't until I watched in horror as my knees started buckling like a newborn giraffe that I knew I was in big trouble. My "ass to grass" squat? More like "back to snap city."
That video was an eye-opener. Since then, I've spent hours and hours of biomechanics learning, coaching sessions, and fixing my own catastrophes. The thing is — bad form doesn't just limit your gains. It's an injury time bomb waiting to explode. And trust me, nothing destroys momentum faster than 6 months of physical therapy.
Let's fix your form before you're another cautionary story.
Why Form Fails (It's Not All About Ego)
Let's first look at why even experienced lifters develop poor form:
- Fatigue build-up — Form deteriorates as you become fatigued
- Mobility constraints — Can't get into proper positions
- Prior injury — Compensating without even realizing it
- Never learned correctly — YouTube University has some flaws
- Progressive overload addiction — Weight increases too fast
The solution isn't always "reduce the weight" (though it's sometimes). More often, it's addressing the root cause.
The Big Three: Squat Form Catastrophes
Mistake #1: The Knee Cave (Valgus Collapse)
What it looks like: Knees caving inward, especially when exiting the hole
Why it happens: Weak glutes, tight hip flexors, reduced ankle mobility
The damage: MCL strain, patellofemoral pain, hip impingement[1]
The Fix:
- Pre-activation: 2x15 lateral band walks before squatting
- Cue: "Screw your feet into the ground" (external rotation)
- Strengthen: Bulgarian split squats with focus on knee tracking
- Mobility: 90/90 hip stretches daily
Mistake #2: The Good Morning Squat
What it looks like: Hips popping up first, turning into a hip hinge
Why it happens: Weak quads, poor bracing, poor bar positioning
The damage: Lower back strain, underdeveloped quads
The Fix:
- Tempo squats: 3 down, 2 second pause
- Front squats to build upright torso strength
- Cue: "Chest up, drive the floor away"
- Core work: Paused front squats, ab wheel
Mistake #3: The Butt Wink
What it looks like: Pelvis tucking under at the bottom
Why it happens: Bad hip mobility, having to force depth you don't have
The damage: Disc compression, SI joint issues[2]
The Fix:
- Only drop down as low as you can control neutral spine
- Daily hip mobility: 90/90s, pigeon pose
- Box squats to learn proper depth
- Strengthen: Good mornings, RDLs for posterior chain
Bench Press: The Shoulder Destroyer
Mistake #1: The Guillotine Press
What it looks like: Bar hitting upper chest/neck area
Why it occurs: Misinterpretation of "full range of motion"
The damage: Shoulder impingement, labral tear
The Fix:
- Bar hits at nipple line or just below
- Tuck elbows 45 degrees, not 90
- Cue: "Bend the bar" (external rotation)
- Shoulders hurt: 4 weeks of dumbbell training
Mistake #2: The Flat Back Special
What it looks like: No arch, shoulders not pulled back
Why it happens: Never learned to set up correctly
The damage: Anterior shoulder pain, reduced power
The Fix:
- Shoulder blades: "Back and down"
- Natural arch (fist should be able to fit under back)
- Feet firmly planted
- Practice setup without weight
Mistake #3: The Bounce
What it looks like: Bar bouncing off chest
Why it happens: Ego lifting, no control
The damage: Broken ribs (yes, really), no muscle tension
The Fix:
- 1 second pause on every rep for 4 weeks
- Tempo work: 3-1-1 (3 down, 1 pause, 1 up)
- Lower weight 10-20%
- Focus on muscle tension, not moving weight
Deadlift: The Back Breaker
Mistake #1: The Scared Cat
What it looks like: Rounded upper back from start
Why it happens: Poor lat engagement, weak erectors
The damage: Thoracic strain, bicep tears[3]
The Fix:
- "Protect your armpits" cue (lat engagement)
- Pull shoulders back AND down
- Deficit deadlifts for upper back strength
- Face pulls and band pull-aparts
Mistake #2: The Stripper Deadlift
What it looks like: Hips shooting up first
Why it happens: Starting with hips too low, quad weakness
The damage: All stress on lower back, hamstring strain
The Fix:
- Film from side: hips and shoulders rise together
- Deadlift lockout pause at knee height
- Romanian deadlifts to practice hip hinge pattern
- Hips higher than you think
Error #3: The Hyperextension Finish
What it looks like: Leaning back at lockout
Why it occurs: Misinterpretation of "lockout"
The damage: SI joint compression, disc issues
The Fix:
- Stand upright, not lean back
- Glutes complete the lift, not lower back
- Cue: "Hips to the bar"
- Practice with Romanian deadlifts
Overhead Press: The Compensation Station
Mistake #1: The Banana Back
What it looks like: Too much arch in lower back
Why it happens: Tight lats, unstable core
The damage: Back pain, lost power
The Fix:
- Squeeze glutes HARD
- Ribs down, neutral spine
- Thoracic mobility work
- Half-kneeling presses to drill position
Mistake #2: The Forward Head
What it looks like: Head protruding forward
Why it happens: Pressing around your face
The damage: Neck strain, impingement
The Fix:
- Start with bar at clavicle
- Press straight up, head through
- "Double chin" position
- Behind-the-neck work (if shoulders healthy)
Pull-up/Chin-up Sins
Sin #1: The Kip Master
What it looks like: Momentum, swinging
Why it happens: Too weak to perform strict reps
The damage: Shoulder instability, no lat development
The Fix:
- Back to band-assisted STRICT pull-ups
- Negative-only work
- Dead hangs for grip
- No kipping until 10 strict reps
Error #2: The Half Rep Hero
What it looks like: Failure to go through full extension at bottom
Why it happens: Dead hang is more difficult
The damage: Elbow tendonitis, decreased gains
The Fix:
- Dead hang all reps
- 2 second hold at bottom
- If too tough: fewer FULL reps > more partials
- Lat pulldowns for volume
Row Violations
Error #1: The Turtle Shell
What it looks like: Rounded upper back during whole workout
Why it happens: Weight too heavy, lack of awareness
The damage: Mid-back strain, no lat involvement
The Fix:
- Chest up, shoulders back
- Lower weight 20-30%
- Pause at contraction
- Face pulls for rear delts
Error #2: The Bicep Row
What it looks like: Arms doing all the work
Why it happens: Lack of mind-muscle connection
The damage: No back growth, bicep strain
The Fix:
- Start with shoulder blades
- Think "elbows back" not "hands up"
- Straps to take away grip limiting factor
- One-arm work for connection
The Mobility Tests You're Failing
Don't fault "tight hips" until you test your actual limitations:
Ankle Mobility Test:
- Knee to wall test: minimum 4 inches
- Fail? You'll compensate everywhere
Hip Mobility Test:
- 90/90 position: both knees at 90 degrees
- Can't sit upright? Hip work necessary
Thoracic Mobility Test:
- Wall angels: full range without arching
- Fail? Your shoulders hate you
Shoulder Mobility Test:
- Behind back reach test
- Can't clasp hands? Pressing problems ahead

Exercise-Specific Cues That Actually Work
Squat:
- "Big breath into belly" (bracing)
- "Spread the floor apart" (knees out)
- "Proud chest" (thoracic extension)
Bench:
- "Bend the bar" (lat engagement)
- "Leg drive through the floor"
- "Pull the bar apart" (on descent)
Deadlift:
- "Push the floor away" (leg drive)
- "Chest up, hips forward" (lockout)
- "Long arms" (don't shrug)
OHP:
- "Squeeze oranges in armpits" (lats)
- "Push yourself away from bar"
- "Tight glutes" (stability)
Red Flags to Stop Immediately
Some pain is training, some is damage brewing:
Stop and Assess:
- Sharp pain anywhere
- Numbness or tingling
- Joint pain (not muscle)
- Pain that increases during set
- Anything in lower back on pressing
Push Through (Carefully):
- Muscle burn
- Fatigue trembling
- General discomfort
- DOMS from previous session
The Ego Check Protocol
Here's the bombshell truth: If you can't execute an exercise with perfect form for 15 reps on the bar alone, you shouldn't be loading it heavy.
Monthly Form Audit:
- Warmup sets as you record them
- Working sets as you record them
- Compare form degradation
- If form breaks down at 70%, that's your new max
Common Mobility Restrictions and Solutions
Tight Hip Flexors:
Affects: Squat depth, deadlift setup
Daily Fix: 2min couch stretch/side
Weekly: Bulgarian split squats
Poor Ankle Mobility:
Affects: Squat form, knee track
Daily Fix: Wall ankle mobilization
Weekly: Calf raises with pause bottom
Restricted T-Spine:
Affects: All presses, front squat
Daily Fix: Cat-cow, thoracic extensions
Weekly: Face pulls, band pull-aparts
Tight Shoulders:
Affects: Low bar squat, overhead press
Daily Fix: Doorway stretches
Weekly: Dislocations with band
Programming Around Form Fixes
You don't need to stop training to get better form:
Option 1: Dedicated Technique Phase (4 weeks)
- Regular lifts only at 60-70%
- Very high frequency (3-4x/week)
- Prioritize perfect reps
- Increase volume using accessories
Option 2: Technique Day Addition
- Keep regular program
- Add a technique day
- 50-60% weight, perfect form
- Record each set
Option 3: Daily Practice
- 10 minutes before each workout
- Empty bar or body weight
- 3x10 perfect reps
- Groove the pattern
The Investment That Pays Dividends
I spent $500 on three sessions with a good coach. Best money I ever spent. They saw things I didn't, fixed issues I didn't know I had, and quite possibly prevented surgery in the future.
If you can't afford coaching:
- Shoot film from several angles
- Put up post form checks online
- Obsessively study proper form
- Be brutally honest with yourself
Final Reality Check
Perfect form is a journey, not a destination. I've been lifting for over a decade and still find things to improve. The difference is now I catch issues in weeks, not years.
Your future self will thank you for every rep you receive correct today. Your physical therapist's kids won't pay for college on your dime. And you'll still be lifting heavy when your ego-lifting friends are nostalgic for their "glory days."
Play the long game. Your joints will thank you.
