Get ready to carry your baby around (a lot!) by keeping your upper body strong.
How to: Standing tall with knees slightly bent, hold two hand weights at your sides with palms facing forward. Inhale with your core breath and, as you exhale, bend at the elbows and bring your hands towards your chest. Be sure to keep your wrists in neutral position at all times. Inhale and slowly lower to the starting position. Beginner: Sit on a stability ball and use light weights. Advanced: Do bicep curls standing on one leg.
