I do real time.
my bag training is 3, 3 min rounds with 1 min of rope in between because my amature mma fights are 3, 3 min rounds with 1 min between rounds.
If you can tear up a bag at high-full intensity and jump rope for recovery, there's nothing standing in a fight that's going to cause you to gas.
Def going to add that. Thank you very much.
