Casey - thanks, we did have fun at the game, especially since they WON! I'm totally just guessing at the calories from pilates - it's not listed as an activity on fitday and I haven't looked anywhere else to try to get an accurate number. Just lazy I guess Do you know of a site that lists this sort of thing? I would be thrilled if it did burn more calories than I am thinking! But I am sure it differs from class to class - probably yoga is the same, but I've never done yoga. I just didn't feel like I got a calorie-inferno pilates workout the other night . . .
