New Research Review: Preacher Curl Vs. Bayesian Curl: Which Builds Biceps Best?
Over the past few years, training a muscle at longer lengths for greater muscle growth has been a hot topic among fitness influencers and sports scientists alike.
This theory has been supported in studies on the quads, hamstrings, and calves, where exercises that emphasize the stretched position have produced superior muscle growth.
But what about the most important muscle of all, the biceps? Does training them in an extended (stretched) position lead to bigger arms?
A recent study put this to the test by comparing the preacher curl and the Bayesian curl to see if training at longer muscle lengths leads to greater biceps hypertrophy and strength gains.
I have written a write-up about this study if you are interested in the results. Hint: there wasn't much of a difference between the exercise.
