I find myself more and more, doing other exercises then simply going to the gym.
I used to just do the gym 4 times a week for my cardio and weights.
Well, this week, I've shoveled the driveway twice (an hour each time) and today I did an hour of pilates. The other week I did Dance Dance Revolution for an hour instead of going the gym as well.
What is your opinion on this? Do you think a person can get enough calories burnt from these activities? For some reason, I still feel guilty that I didn't go to the gym, and think I am 'cheating'.
I think I either need something to feel better about this, or to get told it is not the thing to do so I can go back to doing the gym more.

Dance Dance Revolution burns about 640 calories in an hour. I'd say that you're doing an excellent thing for yourself! Not only are you being productive, but you're having fun and mixing things up which increases the likelihood that you'll stick with working out in the long run! Don't feel guilty! Our bodies need to be surprised!!!
