Hit the Pavement
One of the easiest warm-weather workouts you can get during your workday involves little more than lacing up your sneakers. A jog or fast-paced walk can burn a fair amount of calories and get your adrenaline pumping enough to push you through the rest of the afternoon.
Try circling your parking lot or building on foot. If you work in an office park, hike to another building and back. You'll find you can create numerous, creative routes -- just be sure to use caution in high-traffic areas of the parking lot. To add more fun to your daily laps, find a walking (or running) buddy from your office.
