Chin-Up
intermediate · pull_vertical

Setup
Take an underhand grip about shoulder-width apart with your thumbs wrapped around the bar. This grip lets the biceps help, so most people get a few more reps than with the overhand version.
Execution
- Hang with straight arms, ankles crossed, and brace your belly and glutes lightly.
- Set your shoulder blades down away from your ears before the elbows start to bend.
- Exhale and drive your elbows down toward your ribs until your chin clears the bar.
- Hold one beat at the top with the chest close to the bar and the wrists in line with the forearms.
- Inhale and lower over 3 seconds until the arms are fully straight.
- If the inside of the elbow starts to hurt, switch to a neutral grip or go back to the band-assisted version.
Breathing
Exhale on the way up, inhale on the way down. Steady breathing is what keeps the body from swinging on the bar.
Quick cues
- Blades down first, then pull.
- Drive your elbows to your ribs.
- Chest travels to the bar.
- Three seconds down every rep.
- Crush the bar in your hands.
Common faults
Fault: Arching the back and kicking the legs for momentum
Fix: Squeeze the glutes, cross the ankles and cut the reps to the number you can do cleanly.
Fault: The wrists folding back as you reach the top
Fix: Grip harder and keep the back of the hand in line with the forearm, or use neutral handles.
Fault: Not straightening the arms at the bottom, so every rep gets shorter
Fix: Pause for one beat in a straight-arm hang after every rep.
Fault: Training through pain on the inside of the elbow
Fix: End the set, switch to a neutral grip or horizontal rows, and leave the elbow alone for a few days.
