Good fat loss results combining it with a Keto diet. It is glycogen depleting and gives a good Growth Hormone spike. I had to change it a bit for myself, as the delt work is negligible. But it is a muscular endurance program, which means you lose some on your 1 rep max and possibly some quickness. It's not much for athletic mass for these reasons, but I can see it blowing some people up with a good surplus diet.
