Darth Vader Split Snatched

Fun fact: the late David Prowse, who played the physical role of Darth Vader in the original Star Wars trilogy, was a successful weightlifter who won the British weightlifting championships in 1962, 1963, and 1964 in the heavyweight category at 200 cm and 109 kg. And he was a splitter:

This picture shows his rear knee touching the floor. Unknown whether this was the receipt of a full lift or some kind of overhead split squat exercise.

Considering that the squat lifts were definitely in use at this time, it would be interesting to know why Prowse might have chosen to use the split.
