Stand with your feet in ballet first position, which is heels touching and toes turned out to form a wide "V" shape.
Lift into a high releve position, which entails lifting your heels off the ground and balancing only on the balls of your feet, stretching through the arch. Hold the releve for 30 seconds, then replace your heels on the ground. Repeat several times.
Sit on the ground with your legs extended straight in front of you.
Press your toes into a deep point towards the ground and hold for 30 seconds. Stretch your toes to the ceiling in a flexed position and hold for 30 seconds. Repeat several times.
Stand on a step with your heels hanging off the edge and the balls of your feet and toes firmly planted on the step.
Raise slowly into a releve and then press your heels back down so they extend slightly lower than the step. Hold onto a wall for balance if necessary.
Repeat several times and when comfortable with the movement progress to stretching one foot at a time. Balance on the ball of one foot with the other foot pointed at the opposite ankle. Repeat on the other foot.
