Lie on your back with your knees bent and feet flat. Place a soft ball or pillow between your knees and draw your abdominals in. Inhale, then exhale as you tighten your buttocks and lift your hips until your body forms ￼a straight line [shown].
Squeeze the ball for 2 counts as you do a Kegel, then lower hips. Do 10 times; work up to 3 sets of 10.
Benefit: Strengthens abdominals.
