This is self-reversing
Do one right knee to the corner and start knees around the world on the left knee.
I do this in beginner step, so I start with 8 basics, 8 mambos on the right. Then I do 4 alternating corner knees and one knees around the world. I practice the alternating knees and knees around the world several times before putting it together and cutting it down.
The second time through I do 4 basics, 4 mambos on right, 4 alternating kicks, one knees around the world.
The third time through, I do the combo. Then I repeat all three on the left.
