"Shaul’s guys out in Wyoming get massively strong and powerful on precisely three gym sessions a week, each lasting an hour and no more. Louie Simmons, the single biggest name in gorilla-style competitive power lifting, will tell you that 45 minutes is the max length of any smart training session.
But you can’t spend the first 15 minutes watching CNN from the treadmill and the last 15 “warming down.” Every second has to count, and it all starts with understanding the four basic muscular aptitudes: strength, power, muscle mass, and muscular endurance. [...]
The whole trick to athletic training — and this is true for everybody from bodybuilders to marathoners to noncompetitive athletes just in it for health, or even vanity — is timing each subsequent workout so it hits the middle of that so-called supercompensation peak, when a muscle has already bounced back even stronger than before but hasn’t yet returned to baseline. [...]
It can be hard to believe a true strength coach the first time he tells you that by pressing and dead-lifting on even days, squatting and doing chin-ups on odd days, avoiding all other exercises, and adding a little to the bar each time, you’ll be stronger than you’ve ever been in only a month’s time. Thanks to the fitness industry, we’re so conditioned to equate sophistication with complexity — and to think we’ve got to “work each body part” — that our gut just says, No way; that can’t work. But it works like magic, and the entire body hardens up in unison.
Finally, keep it simple; understand that variety is overrated. Variety does stave off boredom — it’s fun to mix in new exercises all the time — but a guy who hasn’t trained in a long time, if ever, will get stronger faster on the simplest program of squats, dead lifts, and presses, three times a week."
