Raising and lowering the upper body in a sitting position (trunk bend) ► sit up

Partner work

The exercisers sit facing each other, legs slightly bent and feet hooked onto their partner's lower legs. The participants pass a ball back and forth, with their arms practically stretched out and held high. When catching the ball, the momentum of the ball is absorbed and the upper body is lowered as far back as possible (bring the ball over the head towards the floor) without the shoulder blades touching the floor. As you raise your upper body back to the starting position, use the momentum to throw the ball back to your partner.

Attention:
Always keep your stomach tensed and your back straight. Never lower your upper body completely.

Lighten:
Lighter ball or no ball; hold the ball in front of your chest instead of holding it up or in front of you.

Harden:
Heavier ball.
