Work More, Rest Less

While you may have set aside 60 or even 90 minutes for your weekly workout, experts say it's doubtful you're actually getting that amount of activity. And the more social and crowded your gym is, the more you are likely to get distracted into conversations that take up valuable workout time.
The key, experts say, is to talk less and move more - and to decrease your rest periods between exercises.
"If you don't give your body a chance to recover between exercises, it must get in better condition in order to repair itself for the next bout of activity -- so you're automatically getting more out of each workout," says Spencer.
By decreasing rest periods, you can also do more work in the same amount of time, he says, and that means better (and faster) results.
Even in a 30-minute workout, Novak says, reducing rest periods will also increase your challenge level - which, in turn, will increase your body's ability to recover. So you end up in better shape without increasing your workout time.
"The idea is not to increase intensity, but to challenge your body by forcing it to recover more quickly," says Novak.
Franklin agrees: "A body at rest tends to remain at rest; a body in motion tends to remain in motion. So the more you move in any given time period, the easier it becomes to keep moving."
