How to do it

Starting position

  1. Hold dumbbells in both hands and stand straight.
  2. Set your feet hip-width apart.
  3. Keep your gaze facing forward.
  4. Keep your arms naturally by your sides.

Movement

  1. Keep your upper arms stationary and curl the dumbbells up.
  2. Squeeze your biceps hard at the top.
  3. Slowly return to the starting position, feeling the resistance.

Breathing

Exhale as you lift the dumbbells and inhale as you lower them.

Trainer tips

  • Rotate your palms up as you lift
  • Keep your elbow position pinned
  • Extend fully as you lower

Cautions

  • Leaning back can cause a back injury, so keep your upper body upright.
  • Using momentum with heavy weights strains the elbow joints, so start with lighter weight.
  • Heaving the shoulders to use momentum
  • Bending the wrists backward

How GYMKC sets the weight for this exercise

For example, if you do 10 reps with 12 kg in each hand and log that you could have done about 2 more, GYMKC estimates your 1RM per hand at about 17.3 kg.

With the dumbbell, each step is 2 kg (5 lb), so the next weight is 14 kg per hand. Within your 10–15 reps target, the sets you log decide whether to add reps first or add weight.

These numbers are an example of how the calculation works. Your actual prescription is recalculated every set from your own records. See how the calculation works
