I love the idea of a MaB eBook - one filled with tonnes and tonnes of beginner advice - the thing we all wish WE had when we started the whole training adventure.
I think the biggest problem that beginner's have is knowing what the bloody hell to do when they walk in the gym - they see rows and rows of racks, machines, weights and don't even know where to begin. Adding to what people have already said this leads to them doing superfluous exercises like wrist curls and calf raises, when they've got bigger fish to fry - like getting STRONGER.
Filtering through all the crap to give the beginner the basic lifts and routines they need to start off, as well as a way of progressing in them. And what the hell, let them do curls, they're going to do them anyway and people need to enjoy training, not feel like it's a drag. Just as long as the primary focus of the routine isn't BIG GUNZ.
So yeah, a basic, easy to understand, primarily compound focused and strength building routine. Essentially 5x5 mixed in with some bonus lifts like shrugs, chins, dips, push press, RDLs and rack pulls.
