I've tried the bi's and tri's together routine and hate it. After working one, I can't get a full contraction out of the other. For a juicy cycle I upped my training frequency so I can hit every group in 3 days, so chest, anterior delt, and tri's have been together; but soon I'll switch it back to where I was with tri's and shoulders together. I like legs and tri's together...if the gym isn't overcrowded with nut sucking fags trying to get a baby pump consuming the squat rack to knock out some bicep curls which inhibits supersets.
