Supinating Curls

A dumbbell curl that starts with your palms facing in and turns them up as you lift. The turn makes your biceps do both of their jobs: bending your elbow and rotating your forearm.

How to do it

  1. 1Stand tall with the dumbbells at your sides, palms facing in, elbows close to your body.
  2. 2Curl the dumbbells up, turning your palms to face up as they rise.
  3. 3At the top, turn your pinky slightly higher than your thumb and squeeze.
  4. 4Lower slowly, turning your palms back in as you go.

Cues

  • Turn as you lift, so you finish palms up.
  • Elbows stay by your sides.
  • Lower slower than you lift.

Common mistakes

  • Swinging the weights. If your back moves, they're too heavy. Go lighter and keep your body still.
  • Turning only at the top. Start the turn as soon as the dumbbells leave your sides.
  • Elbows drifting forward. Keep them by your sides so your biceps do the work.

Ways you'll see it: Alternating: one arm at a time, switching every rep. Full range plus bottom half: 30 seconds of full curls, then 15 seconds of curls from the bottom to halfway up.

Easier

Go lighter, or alternate arms so each one gets a short rest.

Harder

Take 3 seconds to lower, or finish each set with 15 seconds of bottom half curls.

Try it: 3 sets of 12 to 15 reps, or 30 seconds on and 30 off.

What's the difference between a supinating curl and a regular curl?

A regular curl starts and finishes with your palms up. A supinating curl starts palms in and turns them up as you lift, so your biceps also work to rotate your forearm. You'll usually feel a stronger squeeze at the top.
