Biceps Training

[Rei Koka]

Hey Joe!

Hope you are doing well. I recently saw your videos about preacher curls and before that you released a series of videos about hamstrings on YouTube. I wanted to ask, you prefer the seated leg curl because it trains the hams in their fully lengthened position, but the same analogy can be used for biceps meaning the biceps gets fully lengthened when we extend the elbow and we extend the shoulder joint. So why is it that you prefer preacher curls over smth like reverse cable curl (basically facing away from the machine) when you are actually in a more flexed at the shoulder joint meaning you aren’t training your biceps in its fully lengthened position, I will also have a follow up question for the preacher curls but wanted to get this point clarified first.

Thank you!

You mentioned a lot about lying leg curl but I wasn’t comparing that at all although I get the point why you used that analogy. But in the case of face away cable curls I have seen you do it seated. Or maybe you can even stay in your feet and support your back in the bench if you put the bench at smth like 80° or more and from there you have essentially the same profile but with the biceps being fully lengthened compared to a preacher where you have just a tinny bit of shoulder flexion. Or maybe having the prime bench with the supporting triceps attachments so you can perform the movement. So if you can see the picture ( better than Joe btw 😂😂 just kidding ) but I tried drawing the exercise. Essentially human is putting his back on the bench for support while doing the reverse cable curl. When you put the cable at the lowest position it essentially has the same profile as a preacher curl meaning some load in the fully lengthened position which preacher curl doesnt achieve as you are in a shoulder flexed position although not much and the biggest challenge is in the midrange and then it drops off quite dramatically at the top.
