I'm a total running n00bert. I have always been a shitty runner, and I haven't done any running for the past 6 years. I'm hoping to get picked up by one of the local police departments and if everything goes well, the earliest academy I could qualify for would be in November. So that gives me a little over half a year to get my butt in gear. I have a decent 100m, but I'm a horrible long distance runner. Anyone have any suggestions on improving my cardiovascular endurance? I've considered HIIT but it sounds like it is better for burning fat/cals, which I don't want to do since I'm fairly slim in the first place.
