Query: Totally useless

I purchased the Golden Earth Pilates/Yoga Exercise ball kit, so I don't have all of the pieces of this kit, but I felt obligated to warn people away from this if they want to use the DVD. The ball is fine - that's not hard to do. The video is useless and more than half of it is advertising for other products by the company.The exercises on the video would be fine except that with every single move the narrator says "hold for x seconds" or "repeat 10-20 times" and then they immediately go to the next move. This requires one to STOP what they're doing, pause the video, count it out themselves, and then restart the video. Difficult at best, and very annoying.Fortunately, I purchased the kit at a discount store for a lot less money and didn't really plan to use the video. If I had, I'd have taken it back.
