Despite being the largest muscles in your arms, your triceps are generally not the first muscles you think of when you think about training this body part. That title goes to the big, bad biceps. However, to get strong arms, your fitness routine should include both.

“Triceps are a key muscle for arm and upper-body movements,” says Jordan Fernandez, CPT, a certified personal trainer with Trainer Academy. “You use your triceps constantly because they are responsible for extending your elbows. So anytime you press, reach, or do anything that involves going from a bent-elbow position to a straight-elbow position, you’re using your triceps.”

Strong triceps also contributes to better upper-body strength overall, which will help you maintain your ability to do day-to-day movements as you age, Fernandez explains. You use your triceps to push open doors, get up off of the ground, and lift your carry-on overhead as you travel the globe—and you want to be able to perform those actions well into your older years!

Try this 10-minute triceps workout that your future self will thank you for. Do four sets of each triceps exercise for 10 reps to help you build up your strength.
