I am a 45-year-old and in need of both knees and a hip replacement, perimenopausal, and in constant pain. I absolutely love this game!!! It allows me to get moving when I really don't want to and have fun doing so. I can change intensity and speed to match my daily mobility issues and pain levels You can switch between sitting down and standing up mid game, or between games without changing settings. Generally a lot of fun and definitely one that gets played daily by this old broken bird!!
