t have to buy any special equipment to build muscle in
your hips and thighs
. Instead, try doing body-weight
exercises. Lunges work your knees, legs and hips, and you can do them in extended sets to get a moderate cardiovascular workout. Squats will work your lower body in addition to your abs and back, helping you build strength. Try leg lifts to get your thighs in shape. You can do leg lifts lying on your back or your side, or sitting in a chair.
