 So if you look at the difference here, this is me pipping on my toes, or the balls of my foot, my instep. This is me pivoting on the heels. You're like windshield wipers. Pivot on the heel. Some people say, well, I don't know which one to pivot, let's just pivot in the middle. But the actual proper way to doing this is pivoting on the heel. And a lot of Wing Chun guys are going to say, no, you pivot on the toe or you pivot in the middle. But actually, for a very specific reason, you pivot on the heels. You're like windshield wipers. What you don't want to do is to lift your toes like this and pivot. Do not do that. You want to keep your foot flat on the ground, but still pivot on the heel. So that's a note off the feet. When you do the pivoting, that's very important.
