This move will challenge your balance while working your thighs and glutes.
Stand tall with your feet together. Push your hips behind you and bend your knees, allowing your chest to lean forward. Brace your abs in tight and place both hands on top of your right thigh. Keep your spine naturally straight with a slight arch in your lower back. Balancing on your right leg, flex your left foot and curl your heel up towards your body.
Push out through your heel and extend your left leg straight behind your hip, squeezing your glutes as you press your heel back. Bend your knee and return to your balancing starting position. Do 20 reps and then switch legs and repeat.
Too tough? Do this move near a wall and place your right hand on the wall (left hand stays on your thigh) to help you balance.
