i find this hard to believe, but who knows, maybe it's true...
“A few years ago I started training champion bodybuilder Sharon Bruneau. After her first week of three workouts, she told me she wanted to stop training for a while because she’d already seen an increase in size. She was worried she’d be too big for the Ms. Olympia. After three weeks of no training, I put Sharon through another week of three workouts. Curiously enough, she was stronger on every set of every exercise in that second series of three workouts. That meant she’d succeeded in stimulating an increase during the first series of workouts and that her body had not only produced but also maintained the increase—for three weeks. If the body does in fact decompensate after 96 hours, she would have been weaker, but she was considerably stronger after three weeks of absolutely no weight training."
