Does anyone out there have a specific exercise that peaks your biceps? I have found that the only thing does peaks mine are incline DB curls. cable curls will do it also but DB incline curls seem to really push them up. Currently I am using 40lb each side and got up to 13 reps today on rest pause. I probably could have gotten a few more but I gave up mentally on the first set and I kicked myself for giving up. But now as I type this out it has been 4 hours since then and the biceps are a bit sore.
I also do BB curls and preacher curls at the moment.
