How to do it

Starting position

  1. Sit on a bench and spread your legs hip-width apart.
  2. Hold a dumbbell in your right hand and rest your forearm on your knee.
  3. Position your wrist and palm so they extend past your knee.
  4. Look straight ahead and keep your back straight.

Movement

  1. Slowly bend your wrist downward to lower the dumbbell.
  2. Curl your wrist forcefully upward and contract.
  3. Pause briefly at the top and maintain tension.

Breathing

Inhale as you lower the dumbbells and exhale as you raise them.

Cautions

  • Excessive weight strains the wrist joint, so start with a light dumbbell.

If you feel pain during the exercise, stop. If it continues, talk to a professional.

How GYMKC sets the weight for this exercise

For example, if you do 12 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 18.8 kg.

With the dumbbell, each step is 2 kg (5 lb), so the next weight is 14 kg per hand. Within your 12–20 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
