I haven't done any pulling exercises, because of the long head of the bicep injury, for 4 months - except for different passive (and not too many) active hangs. (I tried doing RC/PE1 and I immediately refrained from it the day pain occurred)
What do you think about Cuban Rotations (with supported elbows against a wall) ? My friend suggested that I should do it, but I wonder... isn't that too advanced?
By the way, I consider training for RC/PE1 again for just once a week.
I was suggested that easier variation would be holding the top position or doing negatives. It's a good idea, but I think I'll do it on a bar or dip bar(on two bars) instead to make the risk of an injury lower..
