Don't like to sweat it out? Struggle with even the most basic group class? Why not water down your workout by enrolling in a water aerobics class? For the person who has trouble with strength training, step or other high-impact classes, a water aerobics class might be just the exercise alternative you have been looking for. {relatedarticles}There is no doubt that this much gentler workout is swimming in goodness. Water workouts can help reduce body fat, tone and build muscles, increase flexibility, burn calories, and help build endurance. Water workouts allow you to exercise every muscle and every joint in the body all at the same time. In the water you're actually using up to 14 times more muscle resistance than when you're doing out-of-water workouts, and you're getting a bigger payoff for your efforts. For example, walking in the park for 30 minutes burns about 135 calories, while walking in the water will burn 264 calories.
