I just started a membership at the local YMCA. I already go there once a week for aquatic therapy and my doctor thought it would be a good idea to exercise in the water on a regular basis. It marks a big change for me.
Yesterday I took a water fitness class and it was the first time since my accident that I've done physical activity led by someone who had no details of my history or condition. It was entirely up to me to judge what I could do and how much was too much. I did fairly well except for the part where I completely over-did it, got massively overstimulated and couldn't get to sleep last night.
So now I know better.
