Well, I'm back from the gym, and my workout was horrendous (as usual.) I'm still on Stage 1, workout A7. I was so tired I couldn't hold my body up for the jackknives (still my hardest exercise.)
So I rested a bit and hit the treadmill. I walked at 3 mph and did the runs at 6 mph. I can't even begin to imagine sprinting on a treadmill without killing myself, so maybe the treadmill won't be the best thing later. But I have a few weeks yet before the real HIIT starts, so I will keep working on it.
Another thought I had while driving home was to go ahead and do the HIIT on the ArcTrainer which I have very good control of, bodywise. I can continue to run on the treadmill for the time being also, and later when the weather is nicer, consider doing the HIIT on the track or something, and really doing all out sprints.
This has been a great discussion. I also like that I have a few weeks to experiment a bit with things too.
BTW, on the treadmill, my walking HR would get down to about 67% and my running up to 85%, but I know I wasn't sprinting or doing an all-out effort. I was surprised that I was even able to run, I never have been able to before, my legs would burn so much. My legs were absolutely fine....YEHAW, I'm becoming FIT!!!
