How to do it
- To begin, stand up with a dumbbell held in one hand. Your feet should be about shoulder width apart from each other. Now fully extend the arm with the dumbbell over your head. Tip: The small finger of your hand should be facing the ceiling and the palm of your hand should be facing forward. The dumbbell should be above your head.
- This will be your starting position.
- Keeping your upper arm close to your head (elbows in) and perpendicular to the floor, lower the resistance in a semicircular motion behind your head until your forearm touch your bicep. Tip: The upper arm should remain stationary and only the forearm should move. Breathe in as you perform this step.
- Go back to the starting position by using the triceps to raise the dumbbell. Breathe out as you perform this step.
- Repeat for the recommended amount of repetitions.
- Switch arms and repeat the exercise.
Form tips
- Start light and own the movement before adding weight.
- Control the lowering phase — don't drop into it.
- Keep breathing; exhale on the hardest part.
- Stop if you feel sharp pain (different from muscle burn).
