🧗 Pull-Up Form Guide
The gold standard of upper-body pulling strength.
The pull-up is the ultimate test of relative upper-body strength. SportsReflector's AI analyzes your scapular engagement, elbow path, chin-over-bar achievement, and full extension at the bottom to give you a 0–100 form score and identify exactly what's preventing you from doing more reps.

4 Pull-Up Mistakes AI Catches
These are the most common Pull-Up form errors — and the ones most likely to cause injury or limit your progress.
Starting the pull-up without first depressing and retracting the shoulder blades causes the traps to dominate and reduces lat activation.
Fix: Before pulling, depress the shoulder blades ('shoulders away from ears'). This engages the lats and protects the shoulder joint.
Not fully extending the arms at the bottom eliminates the lat stretch and reduces range of motion and muscle activation.
Fix: Hang with fully extended arms at the bottom of each rep. This also improves shoulder mobility over time.
Using a kipping motion before building strict pull-up strength places excessive stress on the shoulder joint.
Fix: Build strict pull-up strength first (aim for 5–10 strict reps before learning kipping). Kipping is a skill for CrossFit — not a shortcut for building strength.
Partial range of motion pull-ups don't develop full strength and don't count in most standards.
Fix: If you can't get your chin over the bar, use band assistance or negative (eccentric-only) pull-ups to build strength.
