This is an excellent core stability exercise that really works the abdominals and hip flexors.
- Begin by laying on you back on the floor, hands face down by your sides.
- Slowly begin to lift your legs towards the ceiling.
- When your legs are at a 90 degree angle with the ground, raise your bum off the floor, forcing your feet towards the ceiling and straightening out your body so that it is perpendicular with the floor. Hold this position for a couple seconds and then slowly lower your legs back towards the ground. Be sure not to let your heels touch the ground in between repetitions. This is a fairly advanced exercise so begin with a low number of repetitions and work your way up.
