Single-Arm Bayesian Cable Curl
The Bayesian cable curl uses a low cable behind the body to keep meaningful resistance on the elbow flexors near the lengthened position. The goal is not maximal stretch at any cost, but tension you can reproduce.
Set the cable and elbow position
Face away from a low pulley and step forward until the cable stays loaded with the elbow nearly extended. Do not let the arm drift endlessly behind the torso.
If the upper arm lines up too closely with the cable, external leverage can drop even if the stretch feels bigger.
Use the lengthened position
Let the elbow reach full or near-full extension under control. Do not bounce out of the bottom or shorten it just to move more weight.
Supinated or neutral grip
A neutral handle creates a variation closer to a hammer curl. It changes how the elbow flexors share the work and places more emphasis on the group as a whole, including brachialis.
Track it separately from the supinated version.
Raout
Track the same variation, not just the same load.
Raout keeps side, grip, load and reps together so progression stays tied to the same Bayesian curl setup.
Concentric and eccentric
Curl without letting the whole shoulder move. A small torso adjustment can help maintain a useful cable line, but it should never become momentum.
Return slowly to the fully lengthened position.
Progression and tracking
Keep pulley height, distance, grip and ROM consistent enough to compare sessions.
Raout keeps load, reps, side and setup notes beside today’s workout.
