1
Stand facing a pull-up bar or fixed horizontal bar. Grip the bar with hands shoulder-width apart or slightly wider, using an overhand grip. Position feet together, body upright and engaged.
2
Bend knees and draw them upward toward the chest in a controlled manner. Maintain an upright torso and avoid excessive forward lean. Keep core engaged throughout the movement.
3
Slowly lower legs back down to the starting position with controlled motion, extending knees fully but without locking them completely.
4
Drive knees upward explosively toward chest, contracting the quadriceps and hip flexors. Return to starting position and repeat for prescribed repetitions.
