I am a track and field coach. This is a great teaching aid as I work with the athletes and in my own personal performance running (4:55 mile at 55yrs old). If you want to be the best you can be, you have to be willing to do the work, this teaching aid helps.
This "anatomy" model is not something that can be used to study with. It is the size of an action figures and assembles very poorly. Parts fall off, and it serves little more purpose than something to look at.
