Arm exercises can often focus heavily on your biceps, but the back of your arms are just as important. In order for your arms to look defined, you have to make sure you’re working your triceps just as hard as the front. If you don’t, you may wind up with a muscle imbalance, with your arms being stronger in the biceps area and weaker — and probably a little flabbier to boot — in the back.
Grab a pair of dumbbells and try these moves designed to target your triceps from Devan Kline, an NASM-certified personal trainer and cofounder and CEO of Burn Boot Camp. With a mix of dumbbells and body weight, you’ll feel your muscles firming up in no time at all. To make sure you’ve got the proper form for each move, start with three sets of 10 of each exercise. Once you get more comfortable, increase the circuit to four to five sets of 12 reps. Before you start, use this guide to help choose the right weight for you.
