Bayesian Curl

The Bayesian curl positions the arm behind the body when curling, placing the long head of the bicep in a stretched position and increasing peak contraction. It is one of the most effective cable curl variations.

How To Perform

  1. 1 Set the cable at the lowest position. Stand with back to the machine.
  2. 2 Grip the handle with one hand, elbow behind the hip line.
  3. 3 Curl forward and up to full contraction.
  4. 4 Return to the stretched position behind the hip.

Form Cues

  • ✓ The arm goes behind the body at the bottom — this is what makes this exercise special.
  • ✓ Fully supinate at the top for maximum bicep peak contraction.

Common Mistakes

  • ✗ Not positioning the arm behind the body.
  • ✗ Elbow drifting forward and losing the stretch.
💡 Professor Splits Says:

Progressive overload is the engine of muscle growth. Track your weights and aim to add small increments weekly. For Bayesian Curl, this means gradually increasing load, volume (sets × reps), or decreasing rest periods over time.

FAQ

How many sets of Bayesian Curl should I do?▾
3 sets of 12–15 reps is a solid starting point. Adjust based on your training frequency and overall weekly volume for biceps. Beginners should start with the lower end; advanced trainees can push toward the upper range.
What muscles does Bayesian Curl target?▾
Bayesian Curl primarily targets the Biceps. Secondary muscles include Brachialis.
Is Bayesian Curl good for beginners?▾
Bayesian Curl is beginner-friendly. Focus on technique with lighter loads before adding weight.
How much rest between sets?▾
For Bayesian Curl, 60 sec of rest between sets is recommended. Isolation exercises can typically use shorter rest periods (45–90 sec) to maintain the pump and time efficiency.
