Hey Lion, Mentzer wasn't recomending trainining 3x a week in the mid 90s, he recomended training once every 5 to 7 days, and sometimes every 10 days to 2 weeks.
thats makes it even worse dj,,, i just dont see the body having enough time /frequency of gym hours to change homeostasis and keep changing it into a naturally muscularly developed body that can walk around day in day out with low bf while carrying considerable size.
heres an exampleas to y i think gym time is mor important than diet and or drugs in the long run...
two guys similar height, 115lbs etc typical story start liftining weight to getbig one guy aftr a month keeps liftin learns everything there is to know and keeps on everyday for 10yrs 6-7days per wk, othr guy starts saucin after a month and keeps on saucin for 10yr and learns everything about sauce,,, not so much bout diet and nothing bout training and doesnt hav good training frequency either maybe 4xper wk. now, obviously the guy that lifts weights everyday for 10yrs looks it,almost like he takes juice to but doesnt hav the arm size,although its close but beaten on vascualrity seperation and bodyweight 200 versus 230...
however aside from mor cut vasucalr thicker arms and legs there isnt really much difference at all,,,, except whn the guy stops juicing.
simply put is u dont get better at something by not doing it...
in most cases,,,
all things equal,,, training smart,inury etc., the person that spends more time training will beat all others.period.
