Aging doesn't have to be synonymous with a decline in fitness. Occupational therapist Kevin Shelley shares simple exercises to stay fit and strong from your thirties to your eighties and beyond.

If you've made it into your 80s, congratulations! You've seen and done a lot and are probably convinced by now that the world has gone completely crazy!

From a clinical perspective, health considerations in these years become critical -- and frankly, why wouldn't you want to do all you can to maintain your health? You didn't come this far only to suffer from weakness and a lower quality of life.

Over my years of working with the over-80 population, I've found five exercises that are almost universally effective for my clients.

These exercises combined can help maintain strength and flexibility in your 80s and beyond. I encourage you to add to and modify these exercises to make them the most effective for you, and I encourage you to perform them at least 3 times per week.
