I've known for a while that exercises done in water and swimming is much more beneficial and healthier than other exercises.
I have really weak ankles and I had to quit exercises like jogging all the way back in college. Any time I do exercises on land, I develop multiple problems like tendonitis and ankle sprains that take weeks to months to heal and become more painful every time.
One time in college, I went to my doctor again for tendonitis and she told me that I need to stop doing land exercises and hit the pool instead. She explained to me that in water, our feet, ankle and legs don't carry the weight of our body. Whereas on land, they carry all the weight and exercises that require jumping or bouncing makes it even worse.
I started doing water therapy exercises with her recommendation and started swimming regularly for exercise. I'm happy to say that I have not suffered from sprained ankle or tendonitis since then. Hydrotherapy is just fantastic in my opinion. And you can literally do it your whole life. But exercises like jogging, you can only do for so long until your bones and muscles give out.
