Rotation of the upper body while seated ► oblique crunch / rotational crunch

Individual work

Sitting upright on a chair, cross your arms behind your head or place your hands on either side of your ear (elbows pointing to the side). Alternately lift one leg off the floor and move the elbow crosswise to the knee (bring it together approximately at the level of the navel). Raise the upper body to the starting position and lower the leg again. Switch sides after each exercise.
