Perform this exercise with your prosthetic limbs.
Lie on your back with your legs bent, and with your heels on the floor.
Loop a resistance band around your lower thighs and push your knees apart.
Tighten your buttock muscles and lift your hips up until you have a straight line between your shoulders and knees.
Maintain tension on the band throughout this movement.
Then return to the starting position and repeat.
