One nice feature of the treadmill I have is that there's a small fan you can turn on which will cool your face a tad. It helps if I drink a decent amount of water while riding. I hear that makes you sweat a bit less. The first 20 minutes of my workout tend to be more difficult than the latter 20. I sweat quite profusely during the first half, so much so that I have to keep a shirt or towel or cat nearby to wipe it off. For some reason, during the second half, I produce much less sweat. It's as if my body is saying, "That's all I got for ya. You're on your own now".
I pretty much have to watch TV while working out. Otherwise, it would be quite boring. Because of the noise from the treadmill, I inevitably need to watch something in which I don't need to hear every word coming from the screen. Game shows are good for this, music videos, Countdown with Keith Olbermann.
(One interesting note: I've not watched Countdown in more than a week and have found I've been less stressed. Wonder if there's a connection...)
I've got one more month to go before I get my blood drawn again. On some days, I'm still probably ingesting more saturated fat than I should, but I did quite good yesterday and plan to do the same today.
