If you like running, don't worry about all those theories (some of them half-baked). If you are going to do outdoor running on a track, switch up your routine a little bit. Some days, do your near-race pace 1.5 mile. Other days, go for a lonegr run, maybe 3-4 miles at a much slower pace. And other days, sprint the straight-aways, and jog the corners (pretty much HIIT). The other days will improve your level of fitness, your body composition, and your times for the 1.5mile.

I was wondering if this is a decent method of cardio, not best but decent. Its sort of like MAX-OT cadio where you supposed to go high intensity for 16 min, but I figure by beating my time everyday it keeps my intensity high and lets me chart my progress, set goals, and see improvement easily. How does this compare with HIIT? I do some HIIT routines maybe 1-2 times a week, I like stair running at the stadium here. I'm more curious if this type of training keeps your metabolism up high afterward, I do not want to get stuck in the LISS category, my pulse is about 180 after running? any input would be greatly appreciated.
