FitBit: What the What?!?! Treadmill HIIT Sprint Weirdness

Sunday, January 17, 2016

But first, some random musings:
After working WAY too many hideous RETAIL hours in November and December I was not at all surprised by a 3 pound weight gain when I finally got on the scale in January! (but super glad it was only 3 pounds!)
The amount of stress snacking, extra holiday boozing (when else would I get to drink Tom & Jerrys ?) instead of H20 hydration and precious little time or energy for fitness really make me think I dodged a bullet! But it's a new year and I am forgiving myself for doing what I needed to to survive the Holidays "mentally intact". I guess the importance of many daily steps can't be overstated! (19,713 & 15,562 per day avg in Nov & Dec!) It's the only thing I can think of that kept the number on the scale as low as it was. OOH WAIT! Previous months with strength training and added muscle must have also kept my metabolism going even when I was being naughty. Woohoo MUSCLES! :)

Needless to say, I am certainly not in the cardio shape that I was in early November. So I REALLY can't figure out what is going on with my fitness readings today!
Did a 30 minute treadmill run where I did random HIIT sprints of at least 30 seconds a time and at least 8 or 9 mph! Most of the time it was 30 second sprints and 30 seconds recovery jogging. Sometimes 45 second sprints 60 seconds jogging. Whatever the actual stats...9 mph is insanely fast and 8 mph is nothing to sneeze at either! I was even able to run on the balls of my feet instead of heel first strikes (with flashbacks to my sprinter days in HS/college)!
The part I can't figure out is why my FitBit Charge HR readings for the workout only indicate ONE MINUTE in peak heart rate zone! I was soaked in sweat by the end! I honestly can't believe I am in that good of shape that that sprint duration didn't get my rate up higher! And I was never fully recovered by the beginning of the next interval!

It definitely warrants more testing. Sigh. HIIT will sure kick ya in the butt! Therefore I never REALLY look forward to it. And frankly if I need to be always at 9 mph to get in the peak zone, I'm gonna have to take out extra life insurance on myself! Seriously, that is a crazy speed and while I feel powerful when I'm going that fast I'm willing to bet it looks WAY OUT OF CONTROL! Legs a blur, sweat flying and barely able to reach the one arm forward to hit a slower speed at the end of the interval (you really need them both pumping the same while you are sprinting!)

But despite all the discomfort I am grateful for a body that can be coerced into that kind of workout and survive intact! :)
I guess I should wrap this up and get my strength training in while I am still warm!
Hope all of you that made it through another "hot mess" of a blog entry have a wonderful, productive week! And if you choose to Push It, PUSH IT REAL GOOD! :)

    I was looking for info on HIIT treadmill runs on Spark--thanks for sharing how you did it. But holy cow, woman! That's fast :) My fitbit does wonky things sometimes too, so I'm glad I'm not the only one

    Good gravy that's fast! I can only occasionally get up to 5 mph for about 30 seconds at a time. I'm really impressed!

    I don't have a fitbit, but that's awesome about your HIIT workout! I did one this morning, too! 60 seconds on, 30 seconds recovery jogging, but they were no where near as fast as you. The on was 5.7 mph and the recovery was 4.5. Even when I was at my peak of running and did HIIT, my high intensity was never more than 7.4 mph, you were going incredibly fast! Way to go!!!
