Kansetsu’s review published on Letterboxd:
A nice look into the origins of Westside Barbell and Louie Simmons. For those unaware, Westside Barbell has produced some of the strongest men on the planet. Additionally Louie Simmons is one of the men responsible for bringing training methods from the soviet block to the mainstream.
These people are clearly off, Louie Simmons has put himself through hell and back in his strength journey. The film does a good job of telling some of these crazy stories and it makes it entertaining. Ron Perlman is the narrator and he is great as well.
I see that some people are not happy that the film didn't go into the details of the training methods. There are many sources online and in book form for those who are interested.
