Whether you want a day of fun in the sun or just want to soak it in, catching the waves and the rays is a great calorie-burning day.
- Moderate swimming (think more bobbing, less breaststroke) for an hour burns 236 calories.
- Jogging from the waves with your kids? Do that for one hour and you've burned 472 calories.
- Playing a game of Frisbee for one hour burns 174 calories.
- Spread the towel, reapply the sunscreen, and power through all those thick September magazines: sitting for one hour burns 84 calories for a 155-pound person.
