How to do it
Execution:
  1. 1
    Standing, hold a dumbbell in each hand with a supinated grip.
  2. 2
    Perform 7 partial reps in the bottom half.
  3. 3
    Then 7 partial reps in the top half.
  4. 4
    Finish with 7 full reps, keeping your elbows close to your torso.
Tip: dumbbells let you adjust the grip mid-set — start supinated and stay there.
