Oh the dilemma!
I have been training 3 days per week pretty much since I started training. I've had a few little goes at 4 days per week but haven't been able to do it as I've been quite busy.
My main goal is to pack on some mass and I will be doing a split routine (I have been doing a full body routine for a good while now and fancy a change), although exactly how it's split has not yet been decided.
What do people think? 3 days allows for more recovery, but I'm not sure that will be an issue, especially with a split routine?
Any suggestions to possible splits, be they 3 or 4 days would be appreciated.
