Well the average dude is weak as fuck then, I am just an old bloke training in my back yard by myself and I can manage to do it easy enough, surly these heroes injecting drugs will out lift some old **** training with 40 year old weights in his back yard.
I rep max is the industry and competition standard, what you go off really is not relevant to the rest of the world.
Strength comps are done in one rep max, that's how the world works.
I don't take drugs or supplements, but I actually pick up weight and lift them hard, instead of looking for the easy way out of drugs and supplements like other soft cocks do in an attempt to get out of actually doing hard work.
If you think one rep max are dangerous, it might be time to put your purse away, stop hanging with the girls and start lifting with the men.
Seriously if you been in the gym for more than 12 month and you can't hit a 180kg squat you been wasting your time....
