Walking is easier on your joints, but jogging burns calories more quickly.

It may not be as trendy as Pilates or power yoga, but running still delivers a great fat-burning, stress-reducing aerobic workout.

If you're not careful, you could wind up with a case of heat exhaustion just as easily as the couch potato next door, no matter how fit you might be.

Knowing about common injuries and how to prevent them can keep you on track toward achieving your fitness goals.

Exercising outdoors can be fun and enjoyable, but you should keep personal safety in mind before you head out the door.
