In the fall, the Southeast is in for rain, rain and more rain. Hitting the gym is an obvious way to escape the wet weather, but instead of falling into a treadmill rut and boring yourself half to death, Sweets recommends a pyramid workout that allows you to break up the monotony by using it on various cardio machines

"Hop on your favorite cardio machine, then increase the level of resistance by one or two levels every two minutes until you can no longer handle the resistance," says Sweets. "Then, work your way back down the pyramid. You will burn calories more effectively by changing up the intensity." You can apply this to any machine of your choice: bike, treadmill and the elliptical to keep you motivated. Make mini goals by upping the intensity as your body adapts.

In the Southwest, the cooler weather usually doesn't set in until October, which gives you plenty of time to continue soaking up the great outdoors as summer fades into fall. Instead of driving to the gym, try adding cycling into your exercise regimen. It's a great low-impact option that tones your lower body and also torches calories at the same time.

When you're short on time, turn your ride into an interval workout instead of racking up your mileage. Sweets recommends biking for five minutes to warm up, then start adding short bursts of intense sprints followed by two minutes of recovery; i.e., 30 seconds, 45 seconds, 60 seconds, 75 seconds, 90 seconds; then work your way back down the ladder.
