I don't want to pay for any new workout videos, do you? You can try to find some on Netflix, swap your current ones with friends, or check out this blog post which links to free workout videos that are online!
I actually do not have a favorite type of workout video. I havent worked out to one in years. I am afraid of them, truly, I feel like I am going to injure myself more. When I lose some more weight I might try some but Im not quite ready for it yet!
