Grasp the bar with the palms facing away from you (pronated grip) for a pull-up.
For a chin-up, grasp the bar with the palms facing toward you (supinated grip).
Keep the thumbs wrapped around the bar for a secure grip.
Engage the abdominals and maintain a stable body position.
Avoid swinging or using momentum to initiate the movement.
PROCEDURE:
Pull the body upward in a controlled motion until the chin reaches approximately bar height.
Keep the torso stable and avoid excessive swinging or kicking.
Slowly lower the body to the starting position under control.
Repeat using slow, controlled movements. (12-15 times)
VARIATIONS:
Chin-up - use a supinated grip with the palms facing toward you.
Assisted pull-up - use an assisted pull-up machine or appropriate assistance when a full body-weight pull-up cannot yet be performed with proper technique.
Weighted pull-up - experienced exercisers may add resistance using appropriate equipment while maintaining proper technique.
Muscle-up - an advanced exercise that combines a powerful pull with a transition above the bar and a pressing movement to finish above the bar.
