Nope, Jumproping, running ect are all pointless forms of cardio.
They only work your aerobic state, not anaerobic.
The only way to get better cardio is this.
Get a bunch of slaves/sparring partners/ect...
You go up and spar against one of them for 1 minute(standup) and then another minute(ground).
As soon as the two minutes is up, he leaves and you verse the second person (no breaks).
Do the same thing with the second through 5th person. No breaks in between.
Thats the first day. The next time, add 30 seconds. So it would be 1.5 min stand/1.5 min ground per person.
Increase it by 30 seconds each day.
This is the only way to work anaerboic glycolysis, which is what we use for energy during a fight. Jumping rope, and running are stupid.
