Fitness Shortcuts: The No Time Work Out (cont.)

"You can actually get as much benefit from daily activity as you can by going to a gym -- and maybe more," says Franklin.

Not only that, says physical trainer Dino Novak, ACES, ACSM, but the more you move in your daily life, the more benefits you'll reap from every workout.

"If you are sedentary all week long, when you do hit the gym you've got a lot more ground to cover before you see real progress," says Novak, a master trainer and older adult exercise specialist at the Cooper Institute in Dallas.

In addition, Novak tells WebMD, an active daily life offers fitness advantages you won't find in a gym, no matter how many hours you spend there.

"The whole gym environment, especially if it's machine-based, focuses on very fixed, linear-path movements, but the body doesn't really work that way in real life," says Novak.

For example, he says, if you're walking into the house carrying your dry cleaning, drop your keys, and bend over and turn to pick them up -- all that fixed training you've done in the gym is not going to help much.

"It could even be setting you up for injury if you have muscle imbalances," says Novak.

By putting more activity into your daily life, he says, you'll not only increase your fitness level, but be able to perform routine tasks with more ease -- and, possibly, less risk of injury.

Double Up Your Workout

Another way to sneak more fitness into a busy day is to vary the activities you do during your formal workouts.

Too often, experts say, we get stuck in the rut of doing the same exercise over and over -- be it running on a treadmill, doing circuit training or riding a bike. Yet mastering a single workout isn't necessarily the way to increase fitness. In fact, it might even set you back.

"When the body is doing a set rhythm, it expends less energy than when it's forced into multiple movements," says Novak. The more efficient the body gets at an activity, the more energy it conserves -- and the less you get out of your exercise time.

To increase the burn without adding more time on the workout clock, Novak says, vary your activities, and make each movement as complex and as varied as possible.

"For example, instead of just going for a run, do sprints -- and then stop, start, turn, twist," Novak says. "Add motion and movement into your activity and you'll literally keep your body expending the maximum energy."

Another technique, he says, is to vary your workout equipment. For example, during one gym session you might spend 10 minutes on an elliptical trainer, 10 minutes running on the treadmill, 10 minutes jumping rope, and 10 minutes doing strength training. This means your body works harder, and you'll get more out of your exercise session.

For fitness expert John Ellis Spencer, really focusing on your workout is another way to increase the benefits without working out longer. So skip the reading material on the exercise bike, and don't get wrapped up in a TV show while you're on the treadmill.
