Wall squat: Lean up against a wall. Place your feet two feet from the wall shoulder-width apart, back straight. Press your back into the wall and slowly lower your body as if you’re sitting in a chair (no lower than 90 degrees.) Keep your knees over your ankles, and hold for 30 seconds.
Lunge: Hold onto the back of a chair, standing with feet together. Step back two to three feet with your left foot and bend your right knee no more than 90 degrees, keeping all your body weight on the heel of your right foot. Make sure your front knee does not go past your toes. Repeat 10 times on each leg.
Tap Up, Tap Down: Standing on a step, tap your left foot to the floor as if there were a cold bucket of water in front of you. Bring your foot back up and tap the step. Repeat 10 times, then switch to the right leg.
