Here's What Actually Reduces Fat in Your Arms (Hint: It's Not Just Push-Ups)

Tricep kickbacks are another exercise Russell recommends to tone that area on the back of your arms. "Keep your elbows at your sides through the whole movement," she said.

How to do triceps kickbacks:

• Holding a dumbbell in each hand, hinge forward at the hips, with your knees slightly bent.
• Bend your arms, raising the dumbbells so they sit close to your chest, with your palms facing inwards.
• Kick your arms back until they're fully extended and parallel with the floor; squeeze your triceps.
• Bring your arms back to starting position. Repeat for 12-15 reps.
