Instructions
Lay your torso and waist over padded bench, with your hip fold just off the bench. Legs should be straight below you, with ankles in the supports. Raise legs by extending your hips as high as possible, without your torso coming off the bench. You should feel a strong contraction in your glutes. Return by lowering your legs back to the floor.
Tips
This exercise can be made harder by adding weight. You can also do this exercise without the machine, using a straight weights bench or on a swiss ball.
