Who needs weights when you've got a baby to tote around? Let your little one help you tone up your muscles with simple exercises that are fun for both of you.

Chest Press
Begin by lying flat on your back. Place your hands on either side of your baby's torso and lift her straight up and down. Create resistance by slowing down the motion.

Triceps Dips
Sit on the floor with your knees bent. Put your baby on your lap so that her back is resting securely against the tops of your legs. (Separate your legs slightly to create a cradle). Place your arms about one foot behind your back with your fingertips facing toward you. Slowly lift your body off of the ground by straightening your arms. Keep your knees bent. Bend and straighten your arms while keeping your body off of the ground. Place pillows or sofa cushions on either side of your legs in case you or your baby loses balance.

Biceps Lifts
Stand tall with your arms straight out in front of you. Position your baby facedown on your arms so that her feet are pressing against your chest as you gently grip the tops of her shoulders for support. Without bending your elbows, slightly raise your arms up and down.
