I can't keep up on the ground. I get tired quickly, I lose my speed and explosiveness when I'm on my back, hell, even when I'm on my knees(turtle guard for example).
When I'm standing up wrestling or thai/boxing I can go forever. I don't get tired. When I am on the ground, I get easily tired even when I'm not struggling. I can say for sure that I struggle and move a lot more when I'm striking and wrestling, and I also wrestle heavier guys most of the time(not many guys my size).
Are there any specific drills or conditioning stuff for me to do to improve endurance and explosive speed/power while on the ground. I know "shrimping" is great for speed when escaping, and I love to do shrimp-to-turtle with a weighted vest. It has helped my escapes and reversals a lot.
Are there any endurance specific drills to do while on the ground. And not to forget explosive power.
