In Canada both Keith Russell and Hardy Fink have large collections of gymnastics manuals. (I’d love to see them combine those into a resource library one day.)
Here’s one more for the collection.
Greg Glassman posted some of this classic in the CrossFit Journal Issue 30 – February 2005. The whole article is available on PDF file:
This month we review a small yet dense out-of-print book titled Gymnastics and Tumbling. First published by the U.S. Navy in 1944, Gymnastics and Tumbling is today an obscure reference in danger of extinction. We believe it is an indispensable resource for CrossFitters and intend to keep it alive.
Glassman is a prolific fitness pundit, by the way. Watch for his name.
