Description

One-arm side laterals 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. 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. 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. 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. Lower the dumbbell back down slowly to the starting position as you inhale.
  5. Repeat for the recommended amount of repetitions.
  6. Switch arms and repeat the exercise.

Exercise FAQ

Which muscles should feel like they’re doing most of the work?

You should feel the target muscles working while the rest of the body stays braced. If a joint or the lower back is doing the heavy lifting, reduce load and tighten your setup. Think of it as controlled movement done with repeatable, clean reps.

What should I focus on to keep good form?

Move with control and keep your torso stable. Use a range of motion you can own, and stop the set if you need momentum to finish reps.

What’s the safest way to progress over time?

Add a small amount of reps first, then load. If technique slips, step back and rebuild with cleaner reps.
