Sit on a stability ball. Hold a dumbbell in each hand, palms facing upwards. Keep your elbows close to your sides. Curl the dumbbells up towards your shoulders. Lower the dumbbells down slowly, maintaining control. Repeat for desired number of repetitions.

How to perform the Weighted Seated Bicep Curl (On Stability Ball)

  1. Set up. Set up in a stable, balanced starting position appropriate for the Weighted Seated Bicep Curl (On Stability Ball) using your medicine ball.

  • Move with intent — every rep should feel deliberate, not rushed.
  • Drive force through your biceps rather than momentum.
  • Keep your breathing steady: exhale on the hard part, inhale on the reset.

Common mistakes

  • Using too much weight and losing positional control.
  • Cutting the range of motion short and missing the target muscle.
