The Bayesian Curl is a intermediate-friendly cable strength exercise that targets the biceps, with the forearms working alongside. Here's how to do it right — and what to stop doing.

01 Execution
How to do the Bayesian Curl
Set a single handle on the lowest pulley and select a light weight.
Face away from the stack and take the handle with your palm forward.
Step forward until the cable is taut and your working elbow sits behind your ribs.
Brace your abs and lean slightly forward in a split stance.
Bend the elbow to curl the handle toward your shoulder without letting the elbow move forward.
Lower under control back into the stretch, finish the set, then swap arms.
02 The payoff
Why it earns its spot
Holds the biceps under load at a long muscle length where free weight curls go slack.
Constant cable tension across the whole range, including the bottom of the rep.
Unilateral loading exposes and evens out side to side differences.
03 Don't do this
Common mistakes
Not stepping far enough from the stack, so the arm never gets behind the body and the stretch is lost.
Letting the elbow drift forward, which turns the lift into an ordinary cable curl.
Loading too heavy, so the shoulder and torso swing the handle up instead of the biceps.
Standing square to the cable, which drags the wire across the wrist and cuts the range short.
