I purchased this DVD/CD from a PBS pledge show and it's really terrific. The DVD has exercises to help with joint pain in your back, neck, shoulders, hands and/or your hips, so if you have arthritis in a specific area, the DVD menu gives you the option. Or you can just hit play and do the whole thing. Also has a cd that you can play by the pool to instruct you as you do the exercises. The quality of the images is the best I've ever seen underwater - very clear so there's no guess work. As far as the "frozen smiles" the other person commented on, I welcome a smiling face. If you prefer the drill type of instructor who screams and barks orders at you, this is not the dvd for you. It's soothing. Specially after a hard day at work, I find this program good for stress release.
