Weight Training
Resistance training is one way to keep your body, bones, and muscles strong as you age. As long as your physician approves, you should be adding strength training to your workout 2-3 times a week, at the minimum.
Try bodyweight exercise to begin then expand to free weights, like dumbbells and barbells from there. Preserving muscle will help your metabolism in the long run. This means that you can maintain a healthy weight with only 30-45 minutes of lifting weights a few times a week. Other benefits include burning fat, reducing the risk and effect of osteoporosis, reducing diabetes risk by balancing insulin, improving stability, and preventing back pain.
