What I Need: Rid the Paunch!

Work a few of these moves into your exercise routine three times a week (easing them in minimizes soreness), and then after two weeks, do them all together in one session. Then don’t be surprised if you find yourself surfing the web for bikinis, preparing to reveal your sleek new abs surfside.

Plank pose
Balance on toes and forearms (or palms) for up to a minute, pulling belly button to spine and keeping back straight.
 
Standing bicycle
Stand with feet hip-width apart, knees slightly bent, hands clasped behind head and elbows pointed out to sides. Straighten left leg as you lift right leg, knee bent, thigh parallel to floor. Keeping knee lifted and steady, twist torso toward right. Return to start. Repeat on other side for one rep. Do 10 reps.

Side winder
Stand with feet hip-width apart, knees slightly bent, hands clasped behind head and elbows pointed out to sides. Lift right leg to side, knee bent, thigh parallel to floor. Keeping knee lifted, bend torso to right side, bringing elbow and knee toward each other. Do 10 reps; switch sides; repeat.

Seesaw
Stand with feet shoulder-width apart, knees slightly bent, hands on hips. Lift right leg, knee bent, thigh parallel to floor with foot flexed. Straighten right leg, pressing heel toward floor, as you lean torso backward. Return to knee lift position and repeat five times. Switch sides and repeat.

Forward bend
Stand with feet hip-width apart, knees slightly bent, arms overhead with palms facing in. Lift right leg, knee bent, thigh parallel to floor. Keeping knee lifted and arms raised, bring torso and knee toward each other as close as you can. Return to start; switch sides and repeat for one rep. Do 10 reps.
