Jumping Progressions Series
An across-the-floor jump exercise: pas de bourrée into a jump, then another, all the way along. Start on your right foot each time and try the left side too.
Shoulders stay down. Reaching for height with them does not help, and the plié does the work. Smiling lifts your upper body, and the jeté is a good place to try it.
Clear some space first and take up as much of it as you can.
