My friend encouraged me to keep exercising to overcome hemiparesis.
That's nice of them to do that. Did they suggest specific exercises to you?
No but she told me that training my muscles during exercise can really make a difference.
It's great that exercise will help your condition and it's nice that your friend gave you that information. Just make sure you take it slow and don't overdo it. You could hurt yourself if you exercise too much.
I'll exercise as much as I want to, you don't know that I would hurt myself.
I don't know for certain that you would hurt yourself but it is a possibility. I'm just suggesting that you start out slow and work up to a certain fitness level.
