Kettlebell Curl

Also known as: Bicep Curl (Kettlebell)

You flex the elbow to lift a kettlebell toward the shoulder in a single-joint curl, primarily engaging the biceps muscles. The movement uses a supinated grip and controlled concentric and eccentric phases.

How to do the Kettlebell Curl#

  1. Stand tall with feet hip-width apart and hold the kettlebell in one hand using an underhand (palm-up) grip, arm fully extended.
  2. Tuck your elbow by your side and keep it stationary so only the forearm moves.
  3. Curl the kettlebell upward in a steady motion until your forearm approaches the front of your shoulder.
  4. Pause briefly at the top with tension on the biceps, then lower the weight slowly back to full arm extension.
  5. Complete the desired reps, then repeat the same steps with the opposite arm.
