A skill I don't want to have to use but so one of the big focuses is keeping your hands up. Protect the face and then so here's a jab coming out here then you want to go cross. You want to fully extend and the power comes from the hip so you're also turning your foot, your back foot when you punch. So, boom. Let me see. When you bring that up and keep that cross, keep up that. Keep your hands up. Cross, cross. I learned something new. Yeah. Jab cross. And repetitive so you get a great cardio. Knock it off, you two. It's really fun and you really get into it. That's the whole thing. I can see that. Diane. Maybe a little too into it. The big bag is filled with water?
