I'm not a beginner when it comes to lifting, but I'm not all that experienced either.

I've been doing muay thai bjj and boxing since I was 12 and in those years I've obviously been big into health and fitness so I've been lifting a little on and off but only now I am getting into it properly over the coming summer.

My main goal is to get bigger (6'2 and 170lbs, want to be about 185) and I know programs like 5x5 are the most common programs for beginners to start, but if I'm already an intermediate lifter, decent technique but need to improve, should I jump straight into volume training for mass? Or do 5x5 for a while first?
