Extension and flexion of the legs while seated ► crunch kick

Individual work

Sitting on a chair with your upper body leaning slightly backwards, lift your legs off the floor and bend them (pull your knees towards your body). To hold the position better, hold on to the chair with your hands (e.g. grasp the seat, grip the armrest or cross your arms behind the backrest). From this position, stretch your legs out so that they are pointing diagonally forwards (the further horizontally towards the floor, the more difficult) and bend back into the starting position.
