Building muscle through strength-training will not only increase your strength and tone, but will also increase your metabolism, as muscular people have been shown to burn more calories even when they’re at rest. You could work with weights, do squats, push ups, or crunches, among many other exercises. If going to the gym isn’t for you, try strength-training at home.
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.
