I want to throw off kind of all over again with another technique peak. I want to speak to you about power development of the initiation of power development. We know that strength comes a little bit easier than we've progressed to power. And strength has to be the foundation before power because if you think, how can you apply force quickly if you can't apply force at all? So one of the exercises I like to use is box jumps. If you think of throwing a baseball in the air for travel 50 feet, peaked and came back down, when you catch the baseball, it's the same impact or the same force that you used to take off because you travel the same distance. And so if we cut the landing short, if we caught the baseball before it went to full distance, the impact would be less. It's the same thing with a jump. If you jump up and down in place, you'll have a certain amount of force at impact. But if you land on an object, so you didn't travel the complete distance, the force on the body will be less. Yet we know that jumping is an explosive exercise and this is an evaluation technique for athletes and so forth. So Anthony is just going to show you, he's going to come up, he's going to jump up onto a box that's up a prescribed tight. He's going to land softly and you're going to make sure they don't have knee collapse, knee various, knee valve this upon landing. So okay, Anthony, just take a jump up. Land. Step back. Little more. You see, the impact forces are low. But jumping is a power activity, beginning the fast muscle fibers to fire. And it's a good initiation exercise, the elimination of impact, as well as teaching the patient to start to get eccentric contractions with low impact, which is very important for deceleration and cutting. Alright, thank you very much. Hope this helps you. You
