Halle's worked with trainer Harley Pasternak, who told Health that Halle is a fan of rowing exercises: "[Dumbbell rows] strengthen the rhomboids, the muscles in your upper back that connect your shoulder blades to your spine, giving you a toned back and much better posture." Harley recommends row exercises as a way to achieve sculpted shoulders and a toned upper back — great for backless dresses, bikinis, and tanks!
- Hold a dumbbell in each hand and stand with your feet hip width apart. Keep a slight bend in your knees. Fold your torso forward so your back is almost parallel with the floor and your arms are extended out, in line with your shoulders. Draw in your abs to protect your lower back.
- As you exhale, bring your elbows toward your shoulders and close to your side. To get the upper back working, think of sliding your shoulder blades together. As you inhale, slowly lower the dumbbells back to the starting position. This counts as one rep.
- With control, perform as many reps as you can in one minute.
Use eight- to 10-pound dumbbells.
