Warming up and stretching should be the first thing a dancers does when entering a studio, whether it's for a one-hour class or five hour rehearsal. A thorough warm-up will not only help to prevent injuries, but will also help to prevent long-term wear and tear on the joints and muscles.
Dancers should warm up before class even starts. Arrive at least 15 minutes before class starts to give yourself enough time to be properly warmed up.
Before any stretching can occur, the body temperature needs to be raised which increases blood flow, making muscles, tendons and ligaments more elastic and less likely to be damaged.
Lightly jog around the studio or using a skipping rope for five minutes will get your heart rate up and increase body temperature. This quick cardio warm-up should get you sweating, but shouldn't be so intense that you
are too tired for class.
