So normally I run on the tredmill around 6.8 mph for 3 miles. I read up on HIIT training which had numerous styles of running on a treadmill. I Picked the all out run for 1 min jog for 2 for ten rounds. My sprint was 9 mph and jog was around 5.6,. Im still cutting roughly around 12 pounds would I be better off going back to the steady cardio or the "HIIT" program I just spoke of?
Thanks
