Started some prep work for the heavy ball lift exercise today, and managed to talk a pal into doing a few lifts for me for video reference. 

Also dug out a Xmas present which is 'The Human and Animal Locomotion Photographs' by Eadward Muybridge. I really recommend this to anyone looking for all kinds of locomotion reference. Ranges from males to females, lifting, running, dancing, and animals eating, and doing everything else animals do.
