Pool Therapy / Pool Exercise? Anyone?

Hi all,

Seems like every day becomes more and more challenging. I am wanting to stay active as much as possible... as much as my body enables me too; however, there are days where my joints, etc. just are tired, weak, sore, exhausted, painful.

I have heard that pool therapy / pool exercise is a good way to try to get some exercise in when suffering and that it also should help the pain, etc.

Does anyone have any experience? 

Thanks
