Overwork and poor occupational health and safety conditions, a (non- sprung ) hard floor, a cold studio or theater, or dancing without sufficient warm up also increase risk of injury. To minimize injury, dance training emphasizes strength building and forming appropriate habits . Choreographers and dance instructors will often put certain demands on their students and dancers without taking into consideration that each dancer is faced with different anatomical limitations. Dancers will strive to achieve the ideal aesthetic in their respective dance technique by over compensating for their limitations and thus presenting themselves with a higher risk for injury. Also damage may result from having a student perform movements for which they are not prepared, care must be taken that the student is not "pushed" inappropriately.
