There are different types of HIIT but an easy one to begin with is to simply warm up for 3 minutes on an elliptical machine or by walking.  Then work out for 30 seconds so that at the end of the exercise you feel satisfied.  Reduce the speed to slow down to a moderate pace.  Do this 7 more times or for total 8 intervals. Start with one interval and as your body is ready to take more increase the intervals.  Studies show that HIIT to be the absolute premier cardio for weight loss and optimal health as compared to longer, traditional cardio.
For us ladies there is a dreaded week each month that we hold onto water weight (and usually a bar of chocolate) and guess what, you will be much more forgiving at the end of the week weigh in if you know once a month you just happen to be 5 pounds heavier. You’ll say to yourself, yep that’s my pattern, it’s OK and it will be gone next week. See… sometimes homework can be beneficial.

getfit is great in that it is pretty satisfying to see how my physical activity measures up. It also prompts me to kick myself when the goals are not met. The different elements that allow the community to get to know MIT better (e.g., the tunnel walks) are pretty cool. It provides another avenue for me to connect with my friends, and I think getfit is a great program to enhance wellness at MIT.
