The primary function of this back-of-the-arm muscle is elbow extension—which means it helps you do everything from pushing yourself up off the floor to placing an object on a high shelf, Lee Boyce, CPT, a strength coach based in Toronto, tells SELF. “The triceps assist with that last lockout strength, that strength to fully extend [your arm] over the head.”

Why is training your triceps important?

Your triceps act as a synergist muscle, meaning that it assists your other pressing muscles in pushing movements, Boyce explains. During strength training, your triceps help your bigger muscles, like your pecs and deltoids, complete compound exercises—moves like the bench press, overhead press, or push-up—which work multiple groups.

“Those exercises are going to rely on the triceps for a lot of finishing strength,” Boyce says. “Triceps strength can definitely help with the stability and strength of those movements and then increase the overall force output or power potential that you can have.” So if your goal is to lift heavier weights or get stronger, working your triceps is important to get you there.

Triceps strength also plays an important part in your fitness outside of the gym. While it may sound strange that a muscle in your arms can help you run faster, it actually plays a vital role in your sprints, since it helps you kick your arms behind your body to propel you forward, Boyce says.

What’s the best way to train your triceps?

It may sound surprising, but you shouldn’t focus solely on your triceps: You’ll want to include a combo of compound moves and isolation exercises (which zero in on a smaller muscle group)—especially if you’re a beginner or looking to build general upper-body strength, says Boyce.

The compound exercises help your triceps and related muscles get stronger overall. And adding in some isolation exercises that only involve moving the elbow joint—say, any variation of triceps extensions or triceps kickbacks—can help highlight (and fix) any weaknesses or imbalances in those back-of-the-arm muscles that may be hampering your bigger lifts.

To really make the most of your triceps workout, the same applies as it would for any other strength training routine: You need to slot in a proper warm-up first. This gets the blood flowing throughout your muscles and increases your range of motion. Then when you’re done with your session, cool down afterward to bring your body back to baseline—doing some triceps stretches and other relaxing upper-body moves can feel amazing when your workout is in the books.

What are the best triceps exercises?

There are tons of triceps exercises out there, but all share the same movement pattern: They all have you extend your elbow, though you’ll likely be doing this from different angles.

That means great triceps exercises include overhead triceps extensions, kickbacks, triceps push-downs, and variations of presses and push-ups. Changing up your angle can help you hit the three heads of the triceps just a little bit differently.
