All of my female students remove their make up before practice. Some are removing in the ladies room in the school. I dont tell them to remove it, they do. I guess they feel it may smudge or run doing a sweaty workout. I give them enough time to prepare. Why not wear make up swimming, aerobics, skydiving, etc... There is a "time and place" to wear make up. In sweaty training is not the place...to much emphasis on "looks" than application
