Wow thats a lot of bicep volume
How are they responding to it?
Must get some great arm pumps
Great, honestly. I don't take weekly measurements or anything, but I can SEE improvement and I have had doms almost every workout with this routine, which I rarely used to get with arms.
Bare in mind, I'm doing really short rest periods (30 seconds max, shorter if I feel it), so arm workout usually takes about a half hour and back workout usually takes about that, maybe a little more.
