MRP shake as opposed to a protein shake, it's just easier then rummaging to find something to eat in the middle of the night. Working sets seem to be on point, as I do around the same myself. As far as the reps 6-8 for the bigger muscle groups ie: chest, shoulders and back. 10 -12 for smaller groups, bi's and tri's for instance. Now here is were alot of people seem to get it wrong as did I for the longest time. Legs need a lot more reps, leg press 20 - 25, squats 10 - 15, extensions and leg curls around that 15 mark. When I do legs I do 8 working sets of squats alone with 2 warm ups, plus the regular exercises. My legs in the last few months since I have changed to this have grown 2 - 3 inches. Also try alot of compound movements, try 2 weeks of this....mon,wed,fri...squats, deadlifts and bench no more no less. 5 working sets of each movement. Huge shocker on the system, your body will not know what hit it.
