Instructions

Lie with your back on the floor and place your legs out straight with your ankles resting on the top of a swiss ball. Place your hands to your sides. Bracing your core and maintaining a neutral spine, lift and squeeze your glutes off the floor, raising your hips up until your body is in a straight (declining) line.

In this position raise one leg up as high as you can, keeping your body in a straight line. Lower the leg then repeat on the other leg. Repeat for the desired number of repetitions, alternating the leg being lifted.
