I've recently started my own version of C25K. My treadmill cycles through speed, distance, time and calories to it is hard to watch for the intervals. Plus, since I am usually either engrossed in the MP3 or something on tv I don't usually watch the second hand on the clock either. I'll start my warm up around 3mph and then do the intervals at 4.5 and walking 3.3 or so. I just run until I can't run anymore, typically about 60-90 seconds. I can answer a question if one of the kids asks me something but usually no more than a few words.
I bought a heart rate monitor last week. I bought the Omron HR 100C
I used it for the first time yesterday. I am 32 years old so that puts my max heart rate at 188. When I was running at 4.5mph I was at about 175 which is 93%. Walking at 3.3mph was around 155 which is about 82%. If I drop down to 4mph I can last about 2.5 minutes but not sure of my heart rate is as I was doing that before I bought my HRM.
Here is where I am clueless. This seems high to me because when I was a member of Curves they stressed the 60-70% zone for maximum weight loss.
Anyone have any idea of what I should be aiming for?
