I've had my set since Monday afternoon (HOW DID THAT HAPPEN?).
Since, I have completed the main programs for: Athletic Training, Cardio Supersets, LIC and today, oy, today, I did Afterburn. Maybe I should say Afterburn did me?
Seriously, I dunno? Maybe I was pooped from the previous days workouts but, what-thuh? I was wearing my HRM and found I was consistently up in the mid 170's (I'm just shy of 43 yrs old, @122lbs, 5 foot nothing tall, fyi). I would complete a cycle (both sets) and have to pause the dvd to bring my heart rate back down. I waited (paused the dvd, panted) until I was back down in my 140's and then back at it. Heart rate would go right back up; by the end of the second round of each cycle, I was back up in the 170's. It was insane. I really, really don't know how they managed to make it all the way through at such an intensity. I am weak. They are....inhuman.
That being said, maybe a 170 heart rate is totally normal? I would be super interested to hear what you guys find.
I will go on out there and say, thus far: Worth. Every. Stinkin'. Penny.
