I wasn't suggesting this to people. Just wondering if anyone had heard of it outside of this movie.


In the movie, the guy doing the interview about steroid use in sports was explaining that steroids aren't legal, but other acts of manipulating your body are. Hence the cycler forcing his body to build red blood cells in the weeks prior to a race.



Anyway, I didnt see how the end caps were built. I assume it has something that reduces air flow to a point where you can breath, but not with the same ease as outside the simulator.



So I googled and didn't see the capusule I was talking about but looks like these runners/cyclist use commercial version of this stuff.
