It's vitally important for everyone to keep up their fitness at home.
If you’re an older adult looking to establish an exercise routine, you should, ideally, be able to incorporate 150 minutes of moderate endurance activity into your week. This can include walking, swimming, cycling, and a little bit of time every day to improve strength, flexibility, and balance.

For example, you will gradually lose muscle mass as you age if you don't do anything to maintain it. When you keep or gain more muscle, you may actually live longer and you'll certainly have a better quality of life.
