For three decades we’ve heard endlessly
about the virtues of aerobic(increasing oxygen consumption)exercise. Medical
authorities have praised running and jumping as the key to good health, and
millions of Americans have taken to the treadmill (踏车) to reap the rewards. But

surgeon general’s office has recently embraced strength training as a complement
to aerobics. And as weight lifting has gone mainstream, so has the once obscure
practice known as "Super Slow" training. Enthusiasts claim that by pumping iron
at a snail’s pace-making each "rep" (repeat) last 14 seconds instead of the
usual seven—you can safely place extraordinary demands on your muscles, and call
forth an extraordinary response. Slow lifting may not be the only exercise you
