If you follow me on Twitter (@challengebigman), you’ll know that I was planning on trying some High Intensity Interval Training (HIIT) to see if I can add it to my growing “arsenal” of workout options. So, this evening, instead of my normal run, I replaced my treadmill routine of a warmup walk – 5-mile run – cooldown walk with interval running. You can see in the image above that I started with a 10-minute jog and then alternated between a 35-second sprint and a 1:30 jog for 8 times and a cooldown jog/walk for 5 minutes. My sprint wasn’t going to break any speed records — it was 8 mph. Though I felt that I might’ve been able to move a tad faster, I didn’t want to risk flying off the treadmill on my first crack at this.
I definitely felt this workout but, I didn’t realize how much until about 45 minutes later. My glutes (aka “butt muscles”) hurt. My glutes almost never hurt but, I almost never sprint, either. Heck, I think the last time I came close to a real sprint was about 2 years ago when I managed to injure myself in a basketball game (I was around 300 lbs at the time and not exercising much so, you can guess what a sprint looked like for me). So, sprinting tonight was a relatively new feeling for me. Surprisingly, though, it was actually invigorating. I never thought I would say that about running. The best part was that I finished a challenging workout in a little over half an hour.
The verdict: HIIT is a keeper. I’m looking forward to making this a regular staple in my running workout and, possibly, in other areas as well.
