To do the Cyclone, stand with your feet no wider than hip-width apart. Having your feet wider though does help create a more stable base. Then hold a dumbbell or plate weight in both hands and press the weight overhead.
Lift up onto the balls of your feet with the weight pressed overhead and then slowly begin to circle like a cyclone. Make sure to squeeze your glutes as you keep your heels up and circle. The bigger the circle, the harder the move.
Circle one direction at a controlled pace for a set number of reps or for time then switch directions. Make sure you don’t feel your low back when you circle, but instead make sure to brace your abs and squeeze your glutes. Keep your heels up the entire time.
Beginners can start without using a weight or even do this with their feet flat on the ground instead of raising up onto the balls of their feet.
