A treadmill was the first machine we had in J&G's gym (that and the weights). Back in the day, the gym was really just G's gym, as I (the "J" of that equation) never stepped foot in there. That all changed back in 2006 ... I started walking on the treadmill, and I walked a LOT. I'd up the incline (it went up to 14!) and I'd walk backwards (it had long arms for stabilizing). I had 30+ playlists on my ipod, to match my mood. I walked and I walked ... until one day my treadmill stopped. I had walked it into the ground.
We called a repairman, but it was not able to be fixed. We got the HR 550i (pictured above) as a replacement. It's been fine. It doesn't feel quite as sturdy as my original. It only has an incline up to 10 and no long arms. It does fold up to save space, which is a nice option ... but we are lucky enough to have enough room that we rarely need to do that.
I have to admit, since we added the elliptical to J&G's gym, my treadmill has been a bit neglected. As I've gotten revamped for weight-loss, I've also been jumping on the stationary bike more too... but now it's treadmill time again. The other day, I turned on the treadmill and committed to running (jogging) a WHOLE mile without stopping. That's right, an entire mile! I did it, and I've been doing it almost daily. I'm not following any specific C25K plan or anything, but I do think that (a 5k) is the goal. I did one once, and I'd like to do one again.
