" Do you do chins on back day as well as when you work your biceps?"

I do that chin up hold i mentioned earlier in when i do biceps, just usually towards the end, because i feel it gives me a nice pump....on back day i do deads and Romanians etc but i do wide grip overhand pull ups which i don't really feel in my back....most back exercises are pulling andwill hit your biceps..i was recommending to incorporate pull ups also because the strength can be utilized for doing heavier weight later when targeting biceps I've read
