i want to search for websites that talks about exercise suitable for plus size people. any suggestions?

I've heard of sit down exercises, and videos just for people in this situation. I know knee joints are very delicate. Let me do a quick google check for you.

OK, here's a site with some good ideas. It seems swimming is a really good option as well.

God bless you.

Check out water aerobics in your area-this can help protect you if you have joint issues and it's alot of fun-a good way to meet other people and get some support-good luck to you!
