The Whartons' Stretch Book: Featuring the Breakthrough Method of Active-Isolated Stretching

One of the dirty secrets of the fitness world is that for all the talk about the importance of stretching, many athletes and other fit people don't bother with it. It's hard to gauge the benefits, and it seems as if the time could be better spent running, lifting weights, or perfecting sports skills. This sentiment is expressed by Dr. Bob Arnot in the foreword to "The Whartons' Stretch Book," and he says that the Whartons changed his mind. He went to them with a stiffened hip that he thought needed surgery, but after a regimen using the active-isolated stretching technique, his flexibility in that hip had increased 40 percent.

Active-isolated stretching is very different from what your high-school gym teacher made you do. Rather than holding a stretch for a half-minute, you hold it for just two seconds. This prevents the muscle from activating an instinctual braking device to keep itself from overstretching. Traditional stretching forces that braking to occur, and the Whartons think that's not only counterproductive, but dangerous. If you force too deep a stretch while the muscle is doing all it can to keep itself from being stretched, something's got to give. And a torn muscle will repair itself with scar tissue, ultimately making that muscle less flexible.

The Whartons--a father-and-son personal-training team who've worked with many pro athletes and Olympic medalists--show you how to use their stretches to prepare for dozens of sports, from aerobics to wrestling. Nonathletes get an entire section of the book, which describes stretch routines to get your body feeling better after prolonged driving, sitting, standing, and word processing. The routines are a bit on the longish side--20 minutes or more--but it doesn't seem like much time when you think of how long you have to live in your body, and how much better it will feel if you keep it supple and flexible. --Lou Schuler
