For biceps growth
For biceps growth, Bayesian cable curl rates well ahead on our research criteria: easier on the joints, more stretch.
Both are good choices that train the biceps the same way, so they swap freely. Rotating between them every few weeks is an easy way to vary your training.
The research score comes from these, scored by hand from the studies. Lifter scores appear once an exercise has 10 ratings. How scores work
Bayesian Cable Curl. Arm behind the body puts the biceps under load in its longest position.
Preacher Curl. Big stretch, but bouncing out of the bottom is where elbows get tweaked.
For biceps growth, Bayesian cable curl rates well ahead on our research criteria: easier on the joints, more stretch. Both are good choices that train the biceps the same way, so they swap freely. Rotating between them every few weeks is an easy way to vary your training.
About the same: both are easy to learn.
Bayesian cable curl needs a cable station, so for most people it’s a gym exercise. Preacher curl needs an EZ bar and a bench, so for most people it’s a gym exercise.
Bayesian cable curl: it rates Excellent for joint and recovery cost in our research rubric, against Good for preacher curl.
