I am currently on bed rest, but I exercised regularly for years before getting pregnant (running, resistance training, previously Pilates). My doctor said it would be okay to try Tai Chi for up to 20 minutes at a time. Is the Tai Chi DVD for beginners the safest DVD to try, or is there another DVD that might be better suited for me?

Can you tell me the differences between the T'ai Chi DVD offered here and the one available with the Red Ball?
