If you work triceps predominantly to bring up your bench, is it necessary to add adequate bicep work? I’m pretty sure Westside lifters do this without any problems.
Depends on what you are trying to accomplish. Biceps have very little to do with a big bench, so if you are simply looking for the power, then no you dont need to do equal amount of Bi work. I do very little bicep work, but That is because I have seen too many men with very large arms pull the bicep during the deadlift. I think its rare, but I still dont chance it.
