About the Triceps

Your triceps straighten your elbow joint, like when you do a push-up. They work opposite to your biceps. When you push something away from you, your triceps are working.

  • Long Head: Runs along the inside of your arm. It's the only triceps head that also helps move your shoulder.
  • Lateral Head: On the outside of your arm. It's the most visible part of your triceps.
  • Medial Head: Deep muscle under the other two heads. It's the first triceps head that activates when you start straightening your arm.

Best Triceps exercises

Triceps extend the elbow and are most of your upper-arm mass. Overhead extensions bias the long head; pressdowns and close-grip presses add load.
