Just another way to condition in case you get bored of your normal routine or just want to hit your body in a different manner. Try this bodyweight/or hindu squats - as many as possible and a fast pace pushups pullups standing ab wheel rollouts All of these back to back, no rest , as many as possible for each. My experience: The hindu squats get your lungs going but not too incredibly hard, you dont start to really have trouble breathing til the pushups.... I managed about 150 squats, 80 pushups, 15 pullups, and 5 standing ab wheel rollouts and this took me about 8-10 minutes . I was suckin wind pretty hard after this. I was gonna try a second set but i puked haha, although i think that was due to working out with too much food in me. Give it a shot and see what you can do. I think this is also excellent conditioning for fighting just like burpee rounds.
