Main muscle: biceps
- Lie against an incline bench, with your arms holding a barbell and hanging down in a horizontal line. This will be your starting position.
- While keeping the upper arms stationary, curl the weight up as high as you can while squeezing the biceps. Breathe out as you perform this portion of the movement. Tip: Only the forearms should move. Do not swing the arms.
- After a second contraction, slowly go back to the starting position as you inhale. Tip: Make sure that you go all of the way down.
- Repeat for the recommended amount of repetitions.
