It may not feel that way just yet, but spring is right around the corner—and that means short sleeves, bathing suits, and generally showing off those glorious shoulders of yours. This five-move circuit contours your arm and shoulder muscles for a sexy spaghetti-strap-ready look. So grab a pair of light and heavy dumbbells (say, 5 and 10 pounds) and get to work! Do each exercise for 12 reps, with little to no rest between moves. Rest for a minute or so after you’re done with the set, and then repeat the whole circuit over three or four times for a full upper-body workout.
1. Bent-over Dumbbell Rows
Pick up the heavy dumbbells and stand with your feet hip-width apart. Push your hips back (knees slightly bent) and hinge your torso forward, so it’s approaching parallel to the floor (A). (Keep your chest “proud” and don’t let your lower back hunch forward.) Begin holding the dumbbells end to end, then pull them up by bending your elbows out to the side (B). You want your shoulder blades to pinch together in the back. Control the weights as you bring them back down to the hanging position, but don’t let your chest collapse in.
2. Chest-fly Hand-off
For this one, you’ll need one of your lighter dumbbells. Lie on your back, knees bent, arms raised above your chest, holding the dumbbell in one hand (A). Keep your elbows slightly bent and pointed out toward the sides and open them up out to the sides as if you’re hugging a very large tree (B). Raise your arms back up to center and hand the dumbbell off to the other hand. Count each handoff as a rep.
