How to do it

  1. 01

    Lie sideways on a flat bench with one arm holding a dumbbell and the other hand on top of the bench folded so that you can rest your head on it.

  2. 02

    Bend the elbows of the arm holding the dumbbell so that it creates a 90-degree angle between the upper arm and the forearm.

  3. 03

    Now raise the upper arm so that the forearm is parallel to the floor and perpendicular to your torso (Tip: So the forearm will be directly in front of you). The upper arm will be stationary by your torso and should be parallel to the floor (aligned with your torso at all times). This will be your starting position.

  4. 04

    As you breathe out, externally rotate your forearm so that the dumbbell is lifted up in a semicircle motion as you maintain the 90 degree angle bend between the upper arms and the forearm. You will continue this external rotation until the forearm is perpendicular to the floor and the torso pointing towards the ceiling. At this point you will hold the contraction for a second.

  5. 05

    As you breathe in, slowly go back to the starting position.

  6. 06

    Repeat for the recommended amount of repetitions and then switch to the other arm.

In the app

Dumbbell Lying Supination appears when you own dumbbells and the day's window has room for it. Loads come from Rule 3 (Loads rise when earned, read from RPE, graded strong) and climb on the reps you actually did.

If a machine is taken the engine swaps a same-pattern movement and says why.

If you don't have dumbbells

Same movement pattern, same primary muscles — swap by what you have.
