As the name suggests, this exercise will work your triceps. Start by lying down on your back, with a dumbbell in each hand. Extend your arms upward, with your palms facing one another. At this point, your arms should be fully extended above your chest.
As you slowly inhale, bend your elbows, lowering each barbell to the side of your head (one on each side). Your elbows should be pointing straight up. Exhale, then raise your arm once again. To gain neck support, roll a small towel and place it under your neck.
You don’t need a personal trainer in order to achieve results, get into a routine — achieving toned, more defined arms.
