You want to know what HIIT is? Steve will tell you. Burn more in less time, but pushing out 100% and alternating that with periods of rest or reduced output. I usually do this on my runs where I warm up to an aggressive walk for five minutes, enter the maximum speed that I can run (currently it's 4.5 mph) for 10 minutes, reduce to 4.0 mph for 5 minutes, kick it up to 4.2 for 5 additional minutes, then to my 5 minute cool down. As you know, I'm preparing for a 5k, so what I've been doing in my last few workouts is choosing Day 1 to build up speed, then on Day 2 I work on endurance.
I can't believe how much I'm enjoying running! It feels great!
