Lately I've been doing more smooth dances like waltz and foxtrot where frame is more important than fancy footwork. When I was focusing more on hustle and swing and cha cha which are faster, I noticed my caloric intake wasn't that high. These dances felt more like cardio workouts. Lately I've been gaining a bit of weight and having more cravings in general for carbs. Do the smooth dances which require a lot of rise and fall as well as keeping and maintaining a frame expend more muscle? I notice my body is more tired after practicing waltz. So maybe that's why I'm eating more these days. I've also began sleeping on the floor in order to improve my posture. Oddly, a mattress now feels less comfortable. I'd like to not gain weight before my dance performances next month though. Any advice?
