How to do it

  1. 01

    Pick a dumbbell and place it in one of your hands. Your non lifting hand should be used to grab something steady such as an incline bench press. Lean towards your lifting arm and away from the hand that is gripping the incline bench as this will allow you to keep your balance.

  2. 02

    Stand with a straight torso and have the dumbbell by your side at arm's length with the palm of the hand facing you. This will be your starting position.

  3. 03

    While maintaining the torso stationary (no swinging), lift the dumbbell to your side with a slight bend on the elbow and your hand slightly tilted forward as if pouring water in a glass. Continue to go up until you arm is parallel to the floor. Exhale as you execute this movement and pause for a second at the top.

  4. 04

    Lower the dumbbell back down slowly to the starting position as you inhale.

  5. 05

    Repeat for the recommended amount of repetitions.

  6. 06

    Switch arms and repeat the exercise.

In the app

One-Arm Side Laterals 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.
