How to Perform

Set up a preacher bench and select a kettlebell. Sit or stand with your upper arm pressed firmly against the angled pad, elbow aligned with the pad's peak, arm fully extended.

  1. Grip the kettlebell with an underhand hold.
  2. Curl the kettlebell toward your shoulder, keeping your upper arm fixed.
  3. Squeeze your biceps at the top.
  4. Slowly lower the kettlebell to full extension.
  5. Maintain a slight bend in your elbow at the bottom.
  6. Switch arms after completing reps on one side.

Coaching Tips

Form Cues

  • Keep elbows pinned.
  • Squeeze at the top.
  • Control the descent.
  • No swinging.
  • Focus on biceps.

Breathing

Inhale as you lower the kettlebell, exhale as you curl it up while bracing your core.

Tempo

3-0-1

Range of Motion

Lower until arms are nearly straight with a slight elbow bend; curl until forearm touches upper arm.

Safety

Safety Notes

  • Avoid heavy weights with poor form to prevent bicep strain
  • Warm up elbows and biceps
  • Stop if sharp elbow pain occurs
  • Use lighter weight for bottoms-up variation

Spotting

Spotting not required; self-spot with free hand if needed for heavier sets.

Common Mistakes

  • Using momentum to lift
  • Hyperextending elbows
  • Incomplete range of motion
  • Gripping too tightly causing wrist strain

When to Avoid

  • Acute elbow tendonitis
  • Bicep strains
  • Shoulder impingement

Flexibility Needed

  • Wrist flexibility for grip
  • Shoulder flexion to hold position

Build Up First

  • Basic bicep curl technique
  • Proper hip hinge if using squat variation
