Cardio for Fighting

Hi there!

I am currently flying over to Thailand in October, looking to compete there.

I currently have a mild hamstring injury so I’ve been off for a bit. I am worried I won’t be able to be fit enough to compete there.

Any cardio advice? Anything I could do whilst injured?

Also, regarding running/jogging, how do you guys schedule that? Do you run in the morning and then Muay Thai? Or how do you guys schedule look like?
