How to do it

  1. Sit on a chair. Hold a filled bottle in one hand and rest that forearm on your thigh, palm facing up, wrist just past your knee.
  2. Let your wrist bend down slowly.
  3. Bend only your wrist to lift the bottle up as far as you can — keep your forearm on your thigh.
  4. Pause for 1 second, then lower slowly. Then switch hands.

Breathing: Breathe out as you lift, breathe in as you lower.

How much to start with: 2–3 sets × 12–15 reps (each hand)

❌ Common mistakes

  • Lifting your forearm off your thigh.
  • Moving up and down too fast.

⚠️ Safety

  • Make sure the cap is tight. Stop if your wrist hurts or tingles.
