"Run slowly, run daily, drink in moderation, and don't eat like a pig" Dr. Ernst Van Aaken. Sorry ultrasteve.
IFrom your message it sounds like you may be judging the intensity of your jogging efforts based on a subjective assessment. Very tough to do this correctly when you're just getting started. There are some purists and "zen masters" here who are so in touch with their inner self (or have just been at this for so long) that they instinctively know where their heart rate is, but for most of us - me included - a heart rate monitor is an essential tool to help make sure you're in "the zone" - especially when you're just getting started. You may want to consider getting one if you decide to plunge into LHR. No need to "geek out" with a high end model at the start - a really simple model is all you should need now.
Sounds like you're doing fine. Keep it up. Put in as much volume as you can in that 130-137bpm range. Just do what you can. I would say too that at this low level of intensity, you would benefit from daily walking/jogging. Makes it easier to make it a habit too.
So I guess after saying all of that, my questions is if this is a good way for me to reintroduce running back into my life? Is MAF worth while for someone that is, for all intents and purposes, new to the activity or is it more for people that are trying to improve on a foundation that is already there?
