I would do this routine daily for a few weeks leading up to my competitions. This routine is perfect in my opinion because it is easy to track how well your cardio is developing, and also easy to make it more difficult by using harder exercises or doing it for more time. It will not only increase cardio for your judo but also help your body get used to lactic acid build-up and help your muscular endurance. Maximum power and strength are great for combat sports and I know that you have always believed it to be the most important factor. But over long rounds of sparring or fighting, you need muscular endurance and cardio to maintain your strength/power output. This routine should help with this.
