Adding an inner-thigh squeeze to your basic bridge will tone your inner thighs.
Start on your back with your knees bent and your feet hip distance apart. Place a pillow, a ball, or a toning ring between your knees.
Push up into a bridge. Keep your ribs aligned with your pelvis.
Without raising or lower your pelvis, slowly squeeze your pillow 20 times. Lower the pelvis and bring your knees to your chest to round and relax your back. Then repeat twice for a total of three sets.
