Folding Knife in supine position

Lie on the floor or on an exercise mat. The legs are extended, the arms are thrown behind the head. This will be your starting position. As you exhale, start twisting at the waist while lifting your arms and legs up. Tip: the legs should rise 35-45° off the floor, and the arms at the end of the movement should be parallel to the legs, as shown in the figure. The upper body is completely off the floor. On an inhale, return to the starting position. Complete the required number of repetitions. Variations: To make the exercise more difficult, you can use a medicine ball (medicine ball).
