BodyGuide alternatives

Nice idea, but really needs to expand and give fuller details. There's a lot more to benching, for example, than the 3 lines it gives. Using a spotter, the effect of hand placement, shoulder blade position are all critical. omitting this is makes it potentially dangerous for the beginners it seems to be aimed at. Sounds harsh, but as it is, the lack of detail is either ignorant or disingenuous. I'd love to see this done properly because it has great potential. And it's really important that people understand how their bodies really work.
