How many licks does it take to get to the center of a Tootsie Roll Pop? Who knows and who cares..the fun is the journey to get to the goal! Keep busting ass in the gym and you'll be there and further in no time.
I remember years ago reading articles by Louis, of West-side fame using 500# squatters as examples in the articles. This is when I had pulled my head out of my ass and chose to quit being a gym rat and doing half squats and other stupid shit. I thought I'd be the shit if I could squat 500#. Well now I can rep that shit 8-10 times. Now I'm flirting with "7 wheels", point is it's cool to ponder things like time to do "X" but don't obsess ok, keep things consistent and progressing. Oh and BTW maybe I'm not hip on all these programs but never heard of a 5x2. maybe get with something a bit more "proven like 5-3-1 or a basic West-Side split. Good luck dude.
