Jeffries Skipping the Rope

Jeffries Skipping the Rope (1901) is a documentary directed by J. Stuart Blackton rated 9.0/10.

A splendid subject, showing the champion heavyweight of the world, exercising in his training headquarters. After showing his skill in side-stepping, and fancy steps while skipping the rope at a phenomenal speed, the champion's trainers peel off his sweater and give him a rubdown, during which the mighty muscles on the champion's chest and back are seen to perfection.
