Good morning Turtles. It's my weigh in, and this morning I'm UP by 3.0 pounds!

I'm not panicking because I know why I'm up--a combination of TOM and a little too much baguette yesterday (bread makes me bloaty). I'll concentrate on getting that down next week, once my body has figured out that this is NOT a fun way to be!
Bandit, you're just flying right along! What a great loss. It does sound like the exercise is the trick. The weeks you miss it you don't lose, and then the weeks you make it there you have great losses. You must be feeling great right now.
Judy, it sounds like you're making decisions you're happy with. I'm glad that you're making progress toward a life that will sustain
everything you care about--your family, your activities, AND your health.
Princess, I don't know if I could deal with snow this late in the year! My goodness, it's almost April! Of course, that may be the Southern Californian in me talking.
Ariana, I forgot to answer your question about your workout.

I'm sorry.
The programs that are set up in machines make it really easy to do interval work, and if you're in shape they're a great option. However, if you haven't done work like this before or if you're new to exercise, they're a little bit too intense. Too much, too soon. You said you do a program that's 2 min elevated, 2 min flat? My hesitance with that would be that the working interval--2 minutes at the elevated height--is a really long time to keep your heart rate high. So you'd either not be pushing yourself as high as you need to go (to sustain the interval, you'd have to work a bit easier) or you'd burn out and not be able to do as many sets of intervals.
Now, this is assuming you're concerned about your heart rate and your intensity levels. I'm making assumptions about your goals here. It IS entirely valid to do the program on the machine, and you WILL get more benefit doing that--even if each interval is "easy"--than just working on flat (or at a constant elevation). You will always, without fail and without exception, get more benefit if your workout changes--elevation, intensity, speed, resistance, whatever.
Have a good day, Turtles!
