Okay I have been dancing for about ten years, and I am currently taking 6 classes a week, 3 days. I also started cheerleading at the beginning of the month, 2 days a week. About 3 weeks ago I went on wii fit to find that I gained 5 pounds, last week I gained one more pound, and today I gained another pound! I'm fifteen years old, I'm pretty skinny, about 113 now but I could do with less. does anybody know what could be causing my weight gain or how I can stop this or anything? Thank you in advance.
