i'm posting this here because i know this thread relates to your earlier thread in the other forum:
i've worked out in my garage for a year and a half, with only a barbell, sawhorses, and pull-up bar. the only exercise that really can't be done is the bench press, since i don't have a bench. i make up for those by doing floor presses and dips. in order to save the floor and plates, i put down some heavy duty rubber mats that i bought at home depot for a total of $150. because of that addition, i can do olympic lifts and deadlifts. i will eventually need to get bumper plates and squat stands, but so far this set-up has worked very well.
i have to admit, when i first read your posts, i thought you got the idea for your routine from pavel. the lifts, rep/set scheme, rest periods, workouts per week, etc., sound verbatim like what he advocates in PTP. anyway, i tried that scheme to start up from a long lay-off, and it worked, since i was basically starting from scratch. after a couple of months i stagnated, and changed things around, added exercises, and added conditioning.
if you have any questions relating to the garage training, i'd be glad to help you since i was in the same boat you were in not too long ago.
