I'm training for an MT fight, 3x3 minute rounds. I already do a shitload of plyos, cardio, skills training and sparring, but I also want to implement some training that will go for the exact duration of my fight (or a bit more). Anyone have some suggestions as to which exercises 3 minute cardio rounds could be comprised of? I realise a lot of the choices are obvious (burpees, heavy bag), but in your experience what are the best ways to combine them? Obviously I will have to experiment for what feels right for me, but some pointers might allow me to find what works best more quickly. Good suggestions of exercises I may not have considered?
