Take the plunge. From strength training to jogging to aerobic classes (and let’s not forget the plain old swim), aquatic exercises allow you to keep doing many of the exercises you love, while taking a load off your joints.
Visit the great outdoors. Besides the soothing, relaxing benefits of breathing fresh air and observing nature, the great outdoors provides many opportunities for burning extra calories while having fun. Gardening and other yard work is just one way to firm up your arms and legs, while being productive, too.
