Perfect Chin-Up Technique
The chin-up is a powerful upper body pulling exercise that targets your biceps, lats, and rhomboids with greater bicep emphasis than pull-ups. The underhand grip allows for stronger pulling mechanics and greater muscle activation. ChAIron's AI coaching ensures perfect form and optimal muscle engagement throughout the movement.
Step-by-Step Form Guide
- Grip Setup: Grab pull-up bar with underhand (supinated) grip, hands shoulder-width apart
- Starting Position: Hang with arms fully extended, engage lats and pull shoulders down
- Pull Phase: Drive elbows down and back, pulling chest toward bar until chin clears
- Lower Phase: Control the descent back to full arm extension, maintaining tension
Common Mistakes to Avoid
- Using momentum or kipping to assist the movement
- Partial range of motion (not achieving full extension)
- Allowing shoulders to roll forward at bottom
- Crossing legs or excessive body swing
- Rushing through the eccentric (lowering) phase
