Turns out the appropriate number was 64. 65 if one count the odd one I did with my left arm for no good reason.
I don't want to over do it. I have heard bicep is easy to over train.
I'm just starting training.
So I could probably do more but would it be benefit or have adverse effect, that's the question.
Do you know it it's good to workout biceps and triceps in the same workout?
