A couple years ago (I was 50 at the time) I read some stuff by Martin Berkhan and decided to give it a try. I got measured every other week in a hydrostatic tank and consistently added muscle mass and decreased body fat.
Essentially it has to do with reverse pyramid supersets where the first set is the max you can get 3 reps then you immediately drop 10% and do 3 more reps, drop 10% and 3 more reps, with no break in between.
