How to do the dumbbell alternating seated bicep curl on exercise ball

  1. Step 1: Sit on an exercise ball with your feet flat on the ground and your back straight.
  2. Step 2: Hold a dumbbell in each hand with your palms facing forward and your arms fully extended.
  3. Step 3: Keeping your upper arms stationary, exhale and curl one dumbbell while rotating your forearm until your palm is facing your shoulder.
  4. Step 4: Inhale and slowly lower the dumbbell back to the starting position.
  5. Step 5: Repeat the curl with the other arm.
  6. Step 6: Continue alternating curls for the desired number of repetitions.

Sets, reps and programming

Suggested sets, reps and rest for the dumbbell alternating seated bicep curl on exercise ball by training goal
Goal Sets Reps Rest Effort
Strength 3–5 3–6 3–5 min 1–3 reps in reserve
Muscle growth 3–4 6–12 2–3 min 1–2 reps in reserve
Muscular endurance 2–3 12–20 1–2 min 1–3 reps in reserve

Ranges follow the ACSM position stand on progression in resistance training. Muscle grows across a wide range of loads when sets end close to failure (Schoenfeld et al., 2017), longer rests between heavy sets support strength and size (Schoenfeld et al., 2016), and stopping a rep or two short of failure works about as well as training to failure (Grgic et al., 2022). Estimate your working weights with the strength calculators.
