I'm a fit, stronger guy, but want to be able to whoop some arse on the street better. My cardio is not the best. What is the best way to improve it? Wind sprints? Let's say the average street fight is like 20 seconds. Does this mean I should do like 20 to 30 second wind sprints? Or should I do longer because these can't really improve your cardio?
Thanks!
Thanks!
