Start standing with your right leg lifted a few inches off the ground. Place your hands on your hips, or hold on to the wall or a sturdy chair to help you balance. Keep your core tight and chest lifted.
Swing your right leg directly behind you, extending it as far as you can go while keeping your balance. Keep your core tight, and avoid arching your back.
Swing your right leg forward and up as far as you comfortably can.
This counts as one rep. Repeat for two sets of 10 reps on each side.
