The Online Physical Culture Museum
There are articles and ebooks/pdf's as well as ebooks in html/jpg format on the old-time strongmen and physical culture of that period.
Sometime ago, I surfed across this site when I was looking for information on Farmer Burns. Check out:
for info on Martin 'Farmer' Burns as well as a free pdf download of his "Lessons in Wrestling & Physical Culture", which is the famous Farmer Burns Mail Order Course. Scanned direct from a 1912 set of lessons!
Loads of cool & good information on this site. Enjoy!
