The original Westside guys trained twice a week at Westside in Culver City ( a double garage) though some trained at other places. Frenn was a thrower and worked weights 2 per week, and often more than 2 1/2 hours. When I did night school and had lectures at night twice per week plus large assignments I adopted the 2 day theory, Squats, rows, benches, SLDs (very heavy not hammy style,) incs BB, heavy dips, usually just two pushing exercises and two leg lower back exercises, plus abs, arms occasionally. Went from 160lbs to 200lbs with a 32" waist, at 6 foot, and got some pretty good powerlifts.
Would I do it today, no way, I don't have to but then, no choice.
My son would not lift more than twice per week, he went from 100lbs at 13 with a 45lb bench to 180 at 17 and threw shot at our ALL SCHOOLs nationals, against a guy now on our world champ team, set PL records etc on the way. If he would have trained differently would he have been better, probably , but did it work, ....well a lot of very big (300lbs) guys who threw lots of shot got beat by a small kid (5 foot 8") who picked it up a month before the comp each year. Oh yeah he would be considered slow, to normal in leg speed..
Will it work, if you beleive in it and use your head, no problem....hint lift very heavy and rest 3 mins per set, don't worry about heaps of sets, just lift heavy.
