How to Do the Bayesian Cable Curl

The Bayesian cable curl is a single-arm curl done facing away from the cable, so your arm starts behind your body. That puts the biceps in a stretched position under load from the first inch, which makes it a strong choice for muscle growth.

How to do the Bayesian Cable Curl

  1. 1

    Set a single handle on the lowest pulley and stand facing away from the stack.

  2. 2

    Grab the handle with one hand and step forward until your arm is behind your body with the cable taut.

  3. 3

    Stagger your feet for balance and keep your upper arm slightly behind you.

  4. 4

    Curl the handle forward and up toward your shoulder.

  5. 5

    Squeeze your biceps at the top without letting the elbow rise much.

  6. 6

    Lower slowly until your arm returns behind your body in a stretch.

  7. 7

    Finish all reps, then switch arms.

Form cues to remember

  • Start with your arm behind you
  • Keep the elbow mostly still
  • Squeeze at the top
  • Lower into the stretch

Common mistakes

Swinging the torso forward

Brace and lean only slightly to keep the work in the biceps.

Letting the elbow travel too far forward

Keep your upper arm mostly still, slightly behind your torso.

Losing tension at the bottom

Step far enough from the stack that the cable stays taut.

Using too much weight

Choose a load you can lower slowly through the stretch.

Sets and reps

Muscle growth3 sets of 8–15 reps per arm, 60–90 sec rest
Endurance2–3 sets of 15–20 reps per arm, 45 sec rest

The long stretch can strain the biceps tendon at the shoulder if you go too heavy too fast. Start light and stop if you feel pain at the front of the shoulder.

Bayesian Cable Curl FAQ

What makes the Bayesian curl different?

Your arm starts behind your body, so the biceps are lengthened under tension at the bottom. A standard curl has the least tension there.

Does the Bayesian curl build bigger biceps?

Training a muscle in a stretched position is a well-regarded way to grow it, so it is a useful addition. It works best alongside other curl styles, not necessarily in place of them.

Why use a cable for the Bayesian curl?

The cable keeps tension on the muscle through the full range, including at the bottom where a dumbbell gives little resistance.
