By this point, I think I have all of the bugs worked out. I don’t notice walking on the treadmill as much anymore in terms of being tired or sore. I can use it for 2-3 hours a day pretty easily. Much more than that though and the first thing to get sore is my lower back. Not “pain”, but sore, like it’s getting a good workout or like I’ve been standing around the mall all day. (Hopefully that will get better as I push my limits.) My weight has been very slowly going down. (I started at around 172-173 and my most recent measurement is at around 168). I didn’t exactly have a lot of weight to begin with, so I think that’s a significant amount to lose! (My high school track and field weight was around 160, so that’s my lower limit here.) Blood pressure hasn’t changed much at all, but my beats per minute has gone down to the 40′s. (I think I started in the 60′s). That may have been because of a 3 day backpacking trip at relatively high altitude though, as the BPM came down the day after I got back. But it’s been almost 2 weeks since and it has stayed in the 40′s.
