Mom2Ashli, I too have a bad knee. I started going to Curves last March. Since then my knee is a lot stronger. I don't have as many aches or pains as I did prior to working out. Give a try, but go slowly, you won't notice the difference right away. I didn't realize my knee was getting stronger until one day it hit me, my knee didn't hurt and hadn't hurt for awhile.
I looked at Curves and it seemed like all the machines use your legs to push things. Just bending my knees to put shoes on I hear all the crackle in my knees and they hurt.
