I remember reading an article awhile back about this guy who was around 185 pounds 5'11 and was pound for pound one of the strongest people in the world. I can't remember all his lifts but he was a powerlifter. They had an outline of his routine which was he'd do two sets of each exercise and about 1-2 exercises per body part. Such as standing barbell curls, deadlifts, squats, bench press, shoulder press, etc. The first set would be 40% of his max for 2 reps and the second set would be somewhere around 90% of his max for 1-2 reps.
He would do one workout for the weak and hit all the exercises in one session. then he would take a week off and workout the next week. So it was a every other week kind of thing. They explained he did this in order to make sure he had completely recovered. Now I do know that most people including myself look at that and say "screw that". I wouldn't feel right doing on day of working out every other week let alone once a week.
However, there have been times where I have fallen off and taken a week off and then gotten back into it and have had significant gains. If I am working out consecutivly for 8 weeks I'll normally take that week off. Well most rescently I was in the gym three weeks ago and benched 225 and barely got 2 reps. Then I stopped lifting for those three weeks and didn't eat all that great but it wasn't all that bad. I went back to the gym yesterday upset with myself that I hadn't gone in awhile and ended up putting up 245 for 2 reps and felt I could do 250 for 2 reps. I decided to call it a day at 245 though.
The only thing I supplement with is multivitamins but I've been slacking with that to. So I think the could be a couple of reasons for this. It could either be all that rest let me recoup all the way. Or it could be because I had lifted very hard for 2 years and then lifted off and on for awhile and then when at college I didn't even walk into a wieght room for 6 months. I'm fairly tempted to try to look into this a tad bit more but I just don't think I'll stick with the lifting if I do it once every other week due to me having the tendency to fall off the map as of lately. Thoughts?
