GWYNETH'S SEXY ARM SCULPTOR

A lot of Gwyneth's arm work includes resistance training without weights like this arm series that Tracy developed for her. The movements are very fluid and generally involve a lot of repetitions. Here's an example that Tracy shared with Self:

– Stand with legs together, elbows bent and hands touching at fingertips.

– Bend left elbow, reaching toward center of back, and extend right arm overhead, palm forward. Return to start for one rep. Switch sides and repeat.

– Do two sets of 20 reps.

TRICEPS KICKBACKS

Triceps kickbacks are a classic strength-training exercise focusing on the back of the upper arm.

– Hold a three-pound dumbbell in each hand. Lean your torso forward slightly, keeping your spine straight, and bend both elbows back behind you as high as you can.

– Keeping your elbows in that position, straighten your right arm back with the bottom of your fist pointing up.

– With control, bend your right elbow and bring the weight back in toward your shoulder. Do this 15 times.

– Without taking a break, do 12 to 15 reps on the left side.

– Repeat on both sides for a total of three sets. If you need to take a break between each set and stand up to release your lower back, go for it.

OVERHEAD BEND

– Work on shoulders and triceps with this move from Tracy.

– Stand with feet shoulder-width apart, holding a three-pound dumbbell in each hand.

– Bend your left elbow and bring it to your hip.

– Without twisting your body, bend your torso over to the right and extend the left arm overhead, keeping shoulder down. Lower elbow to hip.

– Do 20-25 reps; switch sides and repeat.
