So I just started on Waterbury's SOB Training after completing TBT and WM. Today was my first day so I'm doing 10x3, and I'm setting up to start deadlifting when one of the fitness instructors approaches me asking me about my goals, workout program etc.
When I tell him about my 10x3 routine I'm doing today he has a hard time not laughing at me in my face. We go on and on but he's absolutely convinced there's no other way to induce hypertrophy than going til muscle failure on exercises. I'm sticking with my 10x3 routine but he keeps blabbing that I won't grow that way and it's purely powerlifting style and I'll end up a fat blob like all powerlifters.
Needless to say I disagree, yet I don't have the science to back it up. Anyone wanna help me to teach this instructor a valuable lesson?
