Instructions
Place your thighs on the padded support and lock in your feet. Your hips should be over the padded thigh support, not touching it. Place your hands over your chest and lower your body down by bending at your hips. Lower yourself down only to the point where your lower back can stay stable and that it doesn't round at the bottom of the movement.
The prime movers of this exercise are the hips, glutes and hamstrings. Raise yourself back up to the start position, or if you can, bring the tops of your legs off the pads slightly to work the glutes and hamstrings a little more. Repeat for the desired number of repetitions.
Tips
To increase the difficulty of this exercise add weight by placing a weight plate across your chest.
