Hi Gen,
Thought to have subscribed already but just commented in the other thread.
If you're not new to lifting, get on with the NROL I'd say. If lifting is new for you (it shouldn't
) start with NROL4W. I'm just owning NROL and never bothered with the other one, but if I were to become a PT I'd certainly buy the other one as well.
And just like Jane said.. (and I'm sure to have said in that other thread), make sure protein is the first thing that goes into your mouth (maybe not literally but plan-wise certainly) unless you're just having a fruit-only snack or doing a carb-up.
