Written byMySetPlan Training Team
Exercise guidance based on established strength-training principles and practical programming.
Bayesian curls position your arm behind your body facing away from a low cable, maximally stretching the biceps long head. This behind-the-body position creates the greatest stretch possible on the biceps, targeting the portion responsible for bicep peak development. Research suggests training muscles in stretched positions may enhance growth.
When to use it
Use for long head emphasis and bicep peak development.
Who it's for
Intermediate to advanced lifters targeting bicep peak.
Coaching Note
Stand facing away from the cable machine with your arm extended behind you. Keep your elbow locked in position throughout—the only movement should be at the elbow joint. Let your arm stretch fully back before curling forward.

What are the best tips for the Bayesian Curl?
This position maximizes long head stretch.
Named for creating stretch similar to lying extensions.
Keep elbow position fixed as anchor point.
When to Use the Bayesian Curl
Program Bayesian curls when long head and peak development is the priority. They work best with moderate weight and controlled tempo (12-15 reps). Use them as a secondary or finishing movement after heavier bilateral curls.
What are common Bayesian Curl mistakes to avoid?
Moving elbow during curl - loses stretch benefit.
Letting your elbows drift away from the intended path during the Bayesian Curl can change which muscles carry the load. Use the elbow position described in the setup cues and keep it consistent through each rep.
Not letting arm go far enough back - limits stretch.
Changing your back position during the Bayesian Curl can alter the movement and make the load harder to control. Brace your midsection and keep the torso position called for by the exercise.
Using too much weight - cant control stretch.
Loading more weight than you can control on the Bayesian Curl often creates compensations that shift work away from your Biceps brachii (long head). Reduce the load until each rep follows the intended path.

How to Program the Bayesian Curl
Strength6-8 reps
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
Muscle Growth10-12 reps
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Endurance15-20 reps
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 3 sets of 10-12 reps per arm. Rest 45 seconds.
