Im still new to judo but have become injured. I cant do anything that involves use of the upper body so thought I'd focus on some footwork drills. Currently I've just been doing a tai sabaki movement to practice moving around , vut was wondering if anyone had any other drills they do for judo footwork ? Someone mentioned one that Dave Camarillo sugested . It is focused on entering for throws but I havent found any footage or diagrams of it online. I couldnt quite follow their description of waht they were on about.
