Aerobic Exercise.

The simplest way to meet this need is walking. Walking is the one of the best exercises for your body. The wear and tear on your joints is lower than jogging. Be sure to start off slower to warm up and increase speed slowly after about 3-5 minutes. To increase the intensity, simply lengthen your stride a bit and speed up your pace. The other strategy for increasing intensity is to increase your speed for short bursts of time.If you prefer, jogging is also good if it doesn’t bother your knees. Just know that walking is just as good if you go fast enough. No big investment needed. All you need is your sneakers, and maybe not even that if you walk on the beach. 30 minutes per day every day has been shown to be the optimal amount of exercise. If you don’t have time all at once, the same benefits are derived even if you break it up into 3 X 10 minute or 2 X 15 minute sessions.
