Knee raises
Getting into position
Stand tall with good posture. Keep your feet and legs about one inch apart and your hands just in front of your body at about waist height. Hold onto a chair for support. Tighten your tummy muscles and look straight ahead.
The exercise
Keeping your weight evenly distributed between both feet, bend your left knee so that your calf comes as far up toward the back of your thigh as possible. Don't move your upper leg at all; bend your knee only. Hold for a couple of seconds, then slowly lower the leg. Repeat with right leg. Alternate legs, build up gradually to 10 repetitions with each leg.
