Gironda did beleive in overload principle, followed by huge rest for bringing up lagging bodyparts. I know Makkawy did train back three times a day, and sometimes multiple days in a row at points. A Gironda favorite was putting the legs of either end of a flat bench on wooden blocks...then we would lie chest down on the bench with our legs bent and feet crossed in the air.....then we would do dumbell rows accentuating the contracton at the top where the dumbells would almost hit the bench. Remember we are talking the early 1980's and equipment was not as specialized as today. We often improvised with boxes, stairs, pieces of wood etc. trying to change the angle of an exercise to hit the muscle where you wanted to. Makkawy had a bad lower back from years of olympic lifting in Egypt as a youth, and therefore could not squat or bent over row in the traditional way. He often cursed to me about not being able to squat (behind Vinces back of course) as he felt it would help his lagging glute/hamstring. We did endless sissy squats (with pelvic thrust motion a the top of the movement) and hacks.
