Wall squats
Press your back and head up against the wall, legs in front of you hips width apart. Slide down the wall, bending your knees and lowering into a squat position, with thighs parallel to the floor and knees at 90 degrees to the ankles. Start with a 10 second hold and progress to 60 seconds.
Modification: slide only part-way down, stopping before legs are parallel
Challenge: alternate lifting feet off the ground a few inches, one at a time
