Quad Sets: Sit down on a straight surface, and tighten quadriceps muscles as tightly as possible. Push the back of your knee towards the floor/surface that you’re sitting on. Hold for 5 seconds, relax for 3 seconds. Repeat 10-15 times.
Straight Leg Raises: Lying on back or in a sitting position, tighten quadriceps and lift leg 12-20 inches off the floor, making sure the leg is kept straight. Bend other leg to remove strain from low back. Hold for 5 seconds, then lower leg slowly. Relax for 2 seconds. Repeat 10-15 times.
Wall Slides: Leaning on wall, slowly lower buttocks toward floor until your thighs are parallel to the floor. Hold for 3-5 seconds. Tighten quadriceps muscle as you return to starting position. Repeat 10-15 times.
Side-Lying Hip Abduction: Lying on side, tighten muscle on front of thigh, and then lift your leg 12-20 inches. Hold for 5 seconds, then lower leg. Repeat 10-15 times.
Side-Lying Hip Adduction: Lying on side, cross your legs, upper over lower and then tighten muscle on front of thigh, then lift lower leg 8-10 inches.
Simple Squats: Stand up straight, and use a squatting motion to bend your legs until they are parallel to the floor. Keep your back straight and keep looking up. Do not bend you knees over your toes. Rather, keep your buttocks as far back as you can, and do not lean forward. Stretch your hands when your legs are parallel to the floor to keep your balance. Hold for 3-5 seconds. Repeat 10-30 times.
