Thanks for the fast reply. I hadn't realised that it was 4
I'll drop the shake from the morning snack.
I tried biceps shoulders and back today, but decided that triceps shoulders chest would be a better split, because those three are used together more, also because my biceps were so shagged (they're definately my weakest point) that they were holding back when I was trying to do shoulder exercises.
The reason why I decided on a three day split is because I keep my sessions are relatively short, my muscles get tired pretty quickly, and I'm flagging majorly by the end. So I think that two shorter sessions on each thing per week will definately be more beneficial than one long one. What do you think?
