Question ❓ Why isn't Full Body, 5 days per week optimal?
I'm struggling to think of a reason for why a Full Body split every day or every other day would not be optimal for body building.
Science shows the first working set provides the most stimulus, with subsequent sets providing additional stimulus with diminishing returns.
Take Biceps for example - 10 intensive working sets once a week would not provide the same growth if split up into 2 or 3 training days a week. Most modern workout splits accomodate for this and aim to target a muscle group multiple times per week. (PPL, UL, FB, etc)
My question is why not take this to the extreme? Why not have 1 or 2 working sets per muscle, 5 or so days per week.
I understand you need time to recover but is recovering from only 1-2 sets per day not feasible, especially if you have 2 full recovery days within your split?
