Heidi and Andrea lifting arm weights With summer comes the arrival of gorgeous sundresses and adorable tank tops. With all the exposure you'll be getting, you'll want your arms to look fit and toned. Using two to five pound weights and a few body-sculpting moves, Fitness and Wellness Expert Andrea Orbeck walks Heidi through an exercise regiment designed especially to tighten up your arms and keep your core strong and long.

Heidi with handweightsBicep Curls
Standing with your feet shoulder width apart and your back straight, curl your arms up while lifting one leg up at the same time, alternating with 10 reps for each side to challenge stability and strengthen your core.

Tricep with Glute Extension
Standing with your feet shoulder width apart and back erect as always, pull your arms into a row, keep knees softly bent, hinge your top half over and straighten arms in and out, keeping elbows pointed and all the weight in your heels. Challenge yourself further by extending one leg out, toe pointed, lifting and lowering your leg as you do the tricep extension.

Deltoids with Calf Raise
Keeping your posture upright and your feet shoulder width apart, bend arms at a 90 degree angle while laterally lifting them up and to the side and popping up onto your toes for extra calf stability and balance.

Just keep up these three exercises two to three times a week with 25 reps and two to five pound hand weights to get your body ready for its sexiest summer yet!
