Your attire should be comfortable and non-restrictive so that you can see your body's outline as you move. Appropriate attire for a dance or fitness class includes a leotard, tights, jazz pants, leggings, T-shirt, tank top and jazz shoes or bare feet.
The warm-up exercises are similar to those of a jazz dance class with some exceptions, although isolation of the chest and pelvis are common in both styles. Keep one section of your body still while moving the chest to the right, left, front and back. Then keep your upper body still as you squat and move your hip/pelvis area right, left, front and back. An instructor might have you isolate your neck and shoulders also and ask you to do knee bends to warm up the upper and lower legs.
In order to "Bogle," you'll create a wave coming down your upper body by facing diagonally while thrusting your chest outward, bringing it back in, contracting your abdominal muscles and thrusting your pelvis outward. This is sometimes called a "roll" in hip-hop dancing. In the "Pepperseed," you'll mimic a pepper shaker by letting your arms hang while you're hunched over and swaying them by initiating with the shoulders. The "Butterfly" requires you to move your legs inward by initiating with your knees and moving them in and out. Dancehall movements such as these are done to reggae rhythms, which will keep you moving and help provide an ideal workout.
