HANGING LEG RAISE
Grasp with a overhand grip and let your body hang. Abdominal muscles are tense. Lower back remains straight and stable, do not arch your back.
Pull your thighs up as far as you can. Then return to the starting position. Hold the tension and repeat.
After each repetition, briefly tap your toes on the floor to stabilise the body.
Higher degree of difficulty: with extended legs or with wide grip.
