How to Perform

Sit on a bench with your forearm resting on a stable surface like a table or thigh, wrist and hand extending over the edge. Hold a dumbbell with a neutral grip, thumb up.

  1. Let the dumbbell hang naturally with wrist in slight ulnar deviation.
  2. Lift your hand upward by bending only at the wrist toward the thumb side.
  3. Squeeze forearm muscles at the top.
  4. Lower the dumbbell slowly back to start with control.
  5. Keep forearm stationary on the support.
  6. Repeat for reps, then switch arms.

Coaching Tips

Form Cues

  • Wrist only, arm still.
  • Thumb leads the lift.
  • Control the descent.
  • Firm grip, no squeeze.

Breathing

Inhale as you lower the dumbbell; exhale as you lift into radial deviation while bracing your core.

Tempo

2-0-2

Range of Motion

From neutral wrist position with slight ulnar deviation to full radial deviation where thumb aligns toward forearm, without elbow or shoulder movement.

Safety

Safety Notes

  • Start with light weight to master form.
  • Avoid if acute wrist pain exists.
  • Stop on sharp discomfort.
  • Progress gradually.

Spotting

Not required; self-supported isolation exercise.

Common Mistakes

  • Jerking the movement.
  • Lifting the forearm off support.
  • Using elbow or shoulder.
  • Gripping too tightly.

When to Avoid

  • Acute wrist injuries
  • Wrist tendonitis
  • Recent fractures

Flexibility Needed

  • Adequate wrist flexion and extension range

Build Up First

  • Basic grip strength
  • Understanding of wrist isolation
