Intervals with Pierce Brosnan

Well, I only got 4 workouts in last week. Plus we had a birthday (read cake) and Easter (read chocolate). So needless to say, my expectations for the scale were pretty low (or high if you're talking about how much weight I expected to gain). But, lo and behold! It said 177.4!
So instead of tempting fate and checking it again, I decided to go with it and let it motivate me for this week!
This week's goals are:
1) 5 workouts - 37 min or more each
2) 2000 calories- recorded each day
3) Take vitamins every day (doctor's orders so I should probably do it)
I wonder if the weight loss is partly because of the training method I tried this week. A friend recommended it and I've heard before that it's a great method.
Basically all you do is speed up and slow down in short intervals. Supposedly getting your body going to make the short bursts of speed makes your body work extra hard. Even more so than just getting to a faster pace and staying at it.
The other cool thing is that if you're only doing it for a short time, you can usually go faster than you would otherwise. Like today, I went up to 5.0 miles an hour (= 12 min. mile pace). I used to go at that speed a lot when I was in better shape. But since I'm just starting out I was afraid to try it. It wasn't bad at all for two minutes.
Oh- one thing I forgot to mention. If you want to try this training method, it's important that you be really well warmed up first or you might pull something. I fast walked for 20 minutes first. On a warmer day it probably wouldn't have taken so long (also, the more in shape I get, the less warm up time I need for interval training).
I also finished watching Mamma Mia on the treadmill this morning. Nothing like a musical with fast-paced songs to get you going! Just don't forget your earplugs for the Pierce Brosnan singing parts. Ouch! It sorta seems like he's trying to put a cowboy twang in his singing. Maybe he thinks it sounds more soulful. Either that or he's just streining so hard to hit the notes he's not paying any attention to how he's pronouncing things. You'd think that someone British wouldn't have to work on pronounciation at all in singing though. Weird. And painful. But he's still fairly attractive for an old guy.
