A lunch-time work out can be fun and effective!

No time to work out? Try a lunchtime fitness break. From CEOs to college students, working out during a lunch break is growing in popularity. But is a lunch-hour workout really effective? The answer is yes. The key is intensity. Research has shown that even just 15 minutes of exercise can net you nearly the same effects as 60 minutes of working out, if you increase the intensity. And don't forget that lunch-hour workouts don't have to take place at a gym. Bike riding, in-line skating, even walking to and from a restaurant can all count as a lunch-hour workout.
