How to perform Standing Inner-Biceps Curl

  1. Stand up with a dumbbell in each hand being held at arms length. The elbows should be close to the torso. Your legs should be at about shoulder's width apart from each other.
  2. Rotate the palms of the hands so that they are facing inward in a neutral position. This will be your starting position.
  3. While holding the upper arms stationary, curl the weights out while contracting the biceps as you breathe out. Your wrist should turn so that when the weights are fully elevated you have supinated grip (palms facing up).
  4. Only the forearms should move. Continue the movement until your biceps are fully contracted and the dumbbells are at shoulder level. Tip: Keep the forearms aligned with your outer deltoids.
  5. Hold the contracted position for a second as you squeeze the biceps.
  6. Slowly begin to bring the dumbbells back to the starting position as your breathe in. Remember to rotate the wrists as you lower the weight in order to switch back to a neutral grip.
  7. Repeat for the recommended amount of repetitions.

Sets & reps by goal

GoalSets × repsLoadRest
Strength3–5 × 3–5Heavy (~85%+)2–3 min
Hypertrophy3–4 × 8–12Moderate (~65–75%)60–90 s
Endurance2–3 × 15–20Lighter (~50–60%)30–45 s

Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.

Form tips

  • Keep the upper arm still and pinned to your side so the movement happens only at the elbow.
  • Each side works on its own, so match the depth and speed of both arms and don't let the stronger side take over.
  • Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
  • Control the lowering phase — a 2–3 second descent builds more than dropping the weight.

Common mistakes

  • Swinging the torso to fling the weight up instead of actually curling it.
  • Letting the dumbbells drift apart or clang together at the top instead of controlling the path.
  • Chasing weight jumps before the current load feels solid on every rep.
