What are the things to be taken care of when choosing a pool design?

Hi all,

I 'm here to get suggestions from you guys. I was recently diagnosed with diabetics and some cardiovascular problems. My husband and I are alone in our house and all the household works are taken care of by our servants. So the doctors advised to do exercise and most importantly asked to swim daily. When I discussed with my husband he suggested installing a swimming pool. We choose the idea of an indoor pool as we can use it for all the 365 days. Last day we consulted an indoor pool construction service.

They have provided us with some designs for the indoor pool. Even though they have suggested some technicalities, we would like to get suggestions from those who use it. That's why I'm here. Do you guys know anything about it? What are the things to be taken care of when choosing a design? Please share it. It would be a great help.

Thanks!
