Hello again,
To answer your question about upper chest, well the machine does not do anything for your chest. But the videos offer a great cardio workout and strengthening workout. The guys on there suck, but you can see where they are going with it and go from there. One of the downsides was that you have to purchase a exercise band ( the ones that look like jump ropes but have resistance). But that wasnt a really big deal. It was only like 8 bucks at target. If you just want to work upper chest, this might not be for you. But if you want to work on your abs and want a good cardio workout , I think it is worth the sixty dollars. As far as spending 60 dollars on a trainer is a good idea, but you will have this alot longer than what you would get from a trainer. I would forget a few things if i was told alot in a hour. But i'm no expert or fitness buff, just giving my opinion and telling you what I know from my experience. By the way, I've been using my machine (just the machine, no cardio or other workout), and i'm closer to a flat tummy, and I have lost a few pounds as well.
