I've just changed my workout 2 weeks ago after 5 years of 25 exercises split roughly 8 per Mon/Wed/Fri (doing 3 x 10 reps in each ). My new regime consists of PTP-style bench/squat/deadlifts/pull-ups. I do 2hr wing chun twice a week. I ride my bike 30min each day to work and back. I also do a fair bit of stomach strengthening stuff like Jandas, full-contact twists, Saxon side bends, bent presses, etc.
Anyway, I got a Polar HRM recently and started a HIIT program, i.e. Taku's intervals running at the local park. The first time out, I looked at the data afterwards and I had a max HR of 210 . I thought maybe it was due to radio interference, but I wasn't near anything obvious (powerlines, etc). I did a run again yesterday, and got a max of 234 . I'm 30 years old, and my resting heart rate is in the low 40's (lowest recorded 41). How is it possible to get a 234? I did look down at one stage while running near max pace and had 191 and I was probably going harder than that at some stages. Am I killing myself?
Thanks in advance.
