DescriptionHang from a chin-up bar with both arms extended at arms length in top of you using wide reverse grip. The legs should be straight down with the pelvis rolled slightly backwards. This will be your starting position.
Raise your knees until legs are bent into 90-degree angle. Exhale as you perform this movement and hold the contraction for a second or so.
Go back slowly to the starting position as you breathe in.
