Query: The Urban Bounder is just OK

It sure did increase my heart rate, and it gave me a fair workout to my legs, my calves, and ankles which always burned the next morning. I don't know if that is normal to have annoying leg pain in the morning and having difficulty getting out of bed. Also, another complaint is that a sales person called me about six months after trying to sell me more workout videos/DVD's which was very unwelcomed! However after a year of not using it, I tossed it to the curb.
