This short video is an overview of Lessons in Wrestling and Physical Culture by Farmer Burns.
You can get this great book at Amazon here.
This book has tons of information. The wrestling may seem old-school but that doesn’t mean it’s not effective. Just try one of the famous toe holds and you’ll see. Plus the physical culture training information is a great place to start.
Farmer Burns is quoted as saying “Deep breathing alone has made many a weak man strong and many a sick man well.” You’ll find much more about that in this book.
