Working your triceps might not always be top of mind, but toning the muscles that run along the backs of your upper arms is key to the smooth functioning of your elbows and to also give bare arms a sleeker look.
From this list, triangle push-ups, dips and triceps kickbacks best engaged these muscles. Here’s how to do them. (For each exercise, do 10 to 15 reps for a complete set. Progress from one to three sets as you get stronger.)
