Description

One arm supinated dumbbell triceps extension focuses on controlled movement and maintaining proper body alignment throughout the exercise. The goal is to create tension where needed while avoiding unnecessary strain or momentum. This helps improve movement quality, joint stability, and overall physical control.

Instructions:

  1. Lie flat on a bench while holding a dumbbell at arms length. Your arm should be perpendicular to your body. The palm of your hand should be facing towards your face as a supinated grip is required to perform this exercise.
  2. Place your non lifting hand on your bicep for support.
  3. Slowly begin to lower the dumbbell down as you breathe in.
  4. Then, begin lifting the dumbbell upward as you contract the triceps. Remember to breathe out during the concentric (lifting part of the exercise).
  5. Repeat until you have performed your set repetitions.
  6. Switch arms and repeat the movement.
  7. Switch arms again and repeat the movement.

Exercise FAQ

How can I make this exercise harder without adding a lot of weight?

What’s a common mistake people make here?

Rushing reps and losing body position. Keep the movement smooth and repeatable so tension stays where you want it. Think of it as controlled movement done with repeatable, clean reps.

Does grip or stance matter?

Yes—small changes can shift what you feel and how stable you are. Pick the most controlled position and keep it consistent while you learn the movement. Think of it as controlled movement done with repeatable, clean reps.
