Ahhh... swimming. With the reduction of gravity, this happens to be one of the most gentle movements. Interestingly enough, it actually burns off more calories than walking or biking! One hour of vigorous swimming will burn up to 650 calories, making it very effective for weight control. This low impact movement is also a great cardiovascular exercise because you are moving against the water’s resistance, which is over ten times that of the air! Blend this activity into your success plan for its splash of fun!
