🏋️ Bench Press Form Guide

Master the king of upper-body strength.

The bench press is the most popular upper-body strength exercise — and one of the most commonly performed with poor form. SportsReflector's AI analyzes your bar path, elbow angle, wrist alignment, arch, and leg drive to give you a 0–100 form score and pinpoint exactly what's limiting your strength.

Common Mistakes

5 Bench Press Mistakes AI Catches

These are the most common Bench Press form errors — and the ones most likely to cause injury or limit your progress.

Flaring the elbows perpendicular to the torso places extreme stress on the shoulder joint and anterior capsule, dramatically increasing rotator cuff injury risk.

Fix: Tuck elbows to 45–75° from the torso. Think about 'bending the bar' to activate the lats and protect the shoulder.

Allowing the wrists to bend back shifts the bar toward the fingertips, reducing force transfer and risking wrist injury.

Fix: Stack the wrists directly over the forearm. Use a false grip (thumbless) only if you have wrist mobility issues — otherwise wrap thumbs around the bar.

Using momentum from a chest bounce reduces muscle tension and time under tension, limiting hypertrophy and strength gains.

Fix: Touch and go with control. Pause 1 second at the chest on technique sets to build proprioception.

Asymmetric pressing (one side higher than the other) indicates a strength imbalance and increases injury risk.

Fix: Use a mirror or AI video analysis to detect asymmetry. Perform unilateral dumbbell press to correct imbalances.

Failing to maintain foot pressure into the floor removes a major stability base, reducing total force output.

Fix: Drive feet into the floor throughout the press. Maintain a slight arch in the lower back (not excessive) to engage the whole posterior chain.

Frequently Asked Questions

Everything you need to know about SportsReflector

For beginners: grip the bar slightly wider than shoulder-width, retract and depress your shoulder blades, maintain a natural arch in your lower back, lower the bar to your lower chest (nipple line), keep elbows at 45–75° from your torso, and press in a slight J-curve back toward the rack. Start with a weight you can control for 3×8 with perfect form.
Shoulder pain during bench press is usually caused by: (1) excessive elbow flare placing stress on the rotator cuff, (2) gripping too wide, (3) lowering the bar too high on the chest (toward the neck), or (4) insufficient shoulder blade retraction. AI form analysis can identify which specific fault is causing your pain.
Most lifters perform best with a grip that places the forearms vertical when the bar is at the chest — typically 1.5–2x shoulder width. A wider grip shortens the range of motion but increases shoulder stress. A narrower grip emphasizes the triceps more. Index fingers on the rings is a common starting point.
The most effective bench press improvements come from: (1) fixing technique (AI analysis identifies your specific weaknesses), (2) progressive overload (add 2.5kg every 1–2 weeks), (3) accessory work (tricep dips, dumbbell flyes, face pulls for shoulder health), and (4) adequate recovery (48–72 hours between chest sessions).
SportsReflector uses computer vision to track 17 body landmarks in real time. It measures bar path deviation, elbow angle at the bottom, wrist alignment, symmetry between left and right sides, and lockout quality — then generates a 0–100 form score with specific corrective cues.
