10 Common Push-Up Mistakes and How to Fix Them

The push-up is the most accessible upper body exercise—no equipment, anywhere, anytime. Yet despite its simplicity, most people perform push-ups with form errors that limit results and cause shoulder or back pain. This guide covers the most common push-up mistakes and exactly how to fix them.

Why Push-Up Form Matters

Good push-up form:

• Protects your shoulders (prevents impingement and rotator cuff issues)
• Works the right muscles (chest, triceps, shoulders, core)
• Builds transferable strength (to bench press and other pushing movements)
• Creates a foundation (for harder variations)

Mistake #1: Elbows Flared to 90 Degrees

What it looks like: Elbows point straight out to the sides, arms form a T-shape.

Why it happens:

• Old-school gym class instruction
• Copying others
• Thinking it targets chest more

The problem: 90-degree elbow flare puts the shoulder in an impingement-prone position. The rotator cuff is stressed, the joint is unstable, and over hundreds of reps, this causes shoulder pain.

How to fix it:

Proper elbow angle: 45-60 degrees from your torso (forming an arrow shape, not a T)

Cues:

• "Elbows at 45 degrees"
• "Point elbows back toward your feet, not out"
• "Arrow, not T"
• "Screw your hands into the floor" (external rotation)

Hand position helps: Turning hands slightly outward (fingers at 11 and 1 o'clock) naturally encourages better elbow tracking.

Mistake #2: Hips Sagging (Banana Back)

What it looks like: Hips drop toward the floor, lower back arches excessively.

Why it happens:

• Weak core
• Fatigue
• Not actively engaging core
• Trying to do too many reps

The problem: Sagging hips means your back is taking the load, not your pushing muscles. This causes lower back pain and doesn't train your chest or triceps effectively.

How to fix it:

The position: Your body should be a straight line from head to heels—a plank with arm movement.

Cues:

• "Squeeze your glutes"
• "Tuck your tailbone"
• "Stay in plank position throughout"
• "Core tight, not just pushing"

If core fails before chest/arms: You need to build core strength separately or regress to incline push-ups.

Mistake #3: Hips Piking Up

What it looks like: Butt high in the air, bending at the hips.

Why it happens:

• Trying to make it "easier"
• Weak chest/triceps
• Poor body awareness

The problem: Piking shifts the load to shoulders and reduces the pushing challenge. You're not training what you think you're training.

How to fix it:

The straight line: Maintain the same body position top to bottom. Hips don't move independently—your whole body moves as a unit.

Cues:

• "Plank throughout"
• "One piece from head to heels"
• "Lower your hips in line"

Mistake #4: Partial Reps (Not Going Low Enough)

What it looks like: Only bending elbows slightly, chest never approaches the ground.

Why it happens:

• Can't do full push-ups yet
• Chasing rep count
• Doesn't realize it's partial

The problem: Partial reps build partial strength. You miss the hardest (and most beneficial) part of the movement.

How to fix it:

Full rep standard:

• Chest should touch the ground (or come within 1-2 inches)
• Full elbow extension at the top
• If you can't do this, regress to an easier variation

The truth about rep counts: 5 full push-ups > 20 half reps. Always.

Regression options:

• Incline push-ups (hands on bench/stairs)
• Knee push-ups (maintain straight line hip to head)
• Negatives (lower slowly, reset)

Mistake #5: Not Locking Out at Top

What it looks like: Arms never fully extend, staying slightly bent.

Why it happens:

• Keeping "tension" on muscles
• Triceps are weak
• Partial reps becoming habit

The problem: Full lockout is part of the range of motion. You're missing tricep engagement at the top, and you're not developing full pressing strength.

How to fix it:

Full lockout: Arms completely straight at the top of each rep. Brief pause, then descend.

Cue:

• "Straight arms at the top"
• "Lock out, then lower"
• "Complete every rep"

Mistake #6: Hands Too Far Forward

What it looks like: Hands positioned in front of shoulders, near head level.

Why it happens:

• Trying to shift emphasis
• Didn't set up properly
• Drifting during fatigue

The problem: Hands too far forward stresses the shoulder in a compromised position and reduces leverage, making push-ups harder without additional benefit.

How to fix it:

Proper hand position: Hands directly under or very slightly below shoulders (toward your waist, not your head).

Setup check: At the bottom of the push-up, your hands should be beside your lower chest/upper abdomen, not beside your shoulders or head.

Mistake #7: Hands Too Wide or Narrow

What it looks like: Either extremely wide (hands way outside shoulders) or extremely narrow (hands touching).

Why it happens:

• Trying to target specific muscles
• Copying variations without purpose
• Not experimenting with what works

Standard push-up width: Slightly wider than shoulder width (1.5x shoulder width is a common guideline).

How grip width affects the movement:

Wider:

• More chest emphasis
• Less range of motion
• More shoulder stress for some
• Harder on shoulder mobility

Narrower:

• More tricep emphasis
• Greater range of motion
• Easier on shoulders typically
• Diamond push-ups are an extreme

Recommendation: Start with standard width. Adjust based on goals and comfort. If shoulders hurt, try narrower.

Mistake #8: Head Dropping or Craning

What it looks like: Looking up at the wall ahead, or head hanging down.

Why it happens:

• Trying to watch form
• Fatigue
• Not understanding neutral spine

The problem: Neck position affects the entire spine. Looking up hyperextends the cervical spine; looking down stresses it in flexion. Both can cause neck pain.

How to fix it:

Proper head position:

• Eyes on the floor about 6-12 inches ahead of hands
• Neck neutral, in line with spine
• Chin slightly tucked

Cue:

• "Pack your neck"
• "Head stays in line"
• "Double chin"

Mistake #9: Speed Demons (Going Too Fast)

What it looks like: Bouncing up and down rapidly, using momentum.

Why it happens:

• Chasing rep count
• Cardio emphasis
• Thinking faster is better

The problem: Speed push-ups use momentum instead of muscle, reduce time under tension, and often involve range of motion that deteriorates as you speed up.

How to fix it:

Tempo guidelines:

• 2 seconds down
• Brief pause at bottom
• 1-2 seconds up
• No bouncing

When speed is okay: For conditioning purposes once you've mastered strict form. But the default should always be controlled.

Mistake #10: Not Engaging Shoulder Blades

What it looks like: Shoulder blades stay retracted throughout, or no scapular movement at all.

Why it happens:

• Thinking of push-ups like bench press
• Not understanding scapular movement
• Never learned proper technique

Shoulder blade movement in push-ups:

Unlike bench press where shoulder blades stay pinned back, push-ups should have scapular movement:

Bottom: Shoulder blades retract (squeeze together) as you lower

Top: Shoulder blades protract (spread apart) as you push up

This is called "push-up plus" when emphasized—pushing so far at the top that your upper back rounds slightly.

Why it matters: This trains the serratus anterior, crucial for shoulder health and overhead stability.

Cue:

• "Spread your shoulder blades at the top"
• "Push through the floor"
• "Reach at the top"

Push-Up Progressions

Can't Do One Push-Up Yet:

Level 1:

• Wall push-ups: 3x15
• Build to hands on counter height

Level 2:

• Incline push-ups (hands on bench): 3x10
• Lower the incline progressively

Level 3:

• Knee push-ups: 3x10
• Maintain straight line from knee to head

Level 4:

• Negative push-ups: 3x5 (lower in 5 seconds)
• Full push-up attempts

Building More Reps:

• Grease the groove (multiple small sets throughout day)
• Focus on perfect reps, not max reps
• Add 1-2 reps per week

Quick Troubleshooting

Shoulder Pain

• Check: Elbow flare, hand position, scapular movement
• Fix: Elbows at 45, hands under chest not shoulders, full scapular range

Wrist Pain

• Check: Wrist position, hand placement
• Fix: Use push-up handles/parallettes, make fists, or do incline

Lower Back Pain

• Check: Hip sag, core engagement
• Fix: Squeeze glutes, brace core, regress if needed

Neck Pain

• Check: Head position
• Fix: Neutral neck, eyes to floor

Elbows Hurt

• Check: Elbow flare, lockout hyperextension
• Fix: Tuck elbows more, don't snap into lockout

Beyond Basic Push-Ups

Once you've mastered 20+ perfect standard push-ups:

Chest emphasis:

• Wider grip push-ups
• Decline push-ups (feet elevated)

Tricep emphasis:

• Diamond push-ups
• Close-grip push-ups

Difficulty progression:

• Deficit push-ups (hands on blocks)
• Archer push-ups
• Single-arm progression

Explosive power:

• Clapping push-ups
• Plyo push-ups

Key Takeaways

1. Elbows at 45, not 90—this protects your shoulders
2. Straight line from head to heels—it's a moving plank
3. Full range of motion—chest to floor, arms locked at top
4. Scapulae should move—retract down, protract up
5. Quality beats quantity—5 perfect reps > 20 sloppy ones

The push-up is a skill that rewards deliberate practice. Don't rush progressions—master each level before moving on. A perfect push-up is beautiful biomechanics in action.
