Pitching is, fundamentally, a rotational movement.⁠ ⁠ Yes, there is a linear component, but a pitcher must ultimately be able to transfer that into rotation for that energy to efficiently make its way from the ground and into the ball.🔑⁠ ⁠ How does that energy work its way from...

Lower body mechanics to throw 95 mph. There are four things about the lower body that I wish I knew when I was a 16 year old throwing 78 miles an hour and trying to throw 90 miles an hour and beyond. The first is the leg lift and how well you're able to start creating momentum toward the target. One of the biggest mistakes people make is thinking they need to fall forward as soon as they lift their leg to create drift. What worked for me was coming to a balance point first and then starting to shift my weight from there. That's still a form of drift, and you see a lot of Japanese pitchers do this, like Yoshinobu Yamamoto. The second component is the back leg and how it creates linear momentum toward the target. One of the biggest mistakes I made was diving too much into the quad. I'd get onto my toes and sink into my quad, which led to less power and actually made rotating much harder. Another mistake I made was squatting as deep as possible into the back leg, almost like a pistol squat. What actually helped me was simply dropping down as quickly as possible. I let gravity pull me down. If you've created enough drift, even just a slight drift, that drop will create linear momentum down the mound. The third component is getting the pelvis to rotate into foot plant. The biggest thing here is matching your pelvis plane of rotation and making sure the pelvis rotates down into foot plant rather than rotating upward. One of my favorite cues for this is to slam the knee down or get onto your shoelaces. The last component is simple. It's the lead leg block. You're trying to block all of the momentum you've created like your life depends on it. For me, I tried to extend as high as I could. That actually helped my pelvis continue to rotate because as the front leg extends, the pelvis gets more open. Those are the four things I wish I knew about the lower body when I was trying to gain pitching velocity.

Elon Musk just weaponized gravity. The entire trucking industry has a physics leak bleeding billions. Musk just sealed it. Most people look at the Tesla Semi and see a cleaner diesel. A truck that swapped a gas tank for a battery. That is a complete misread of the physics. Musk: “Let’s say you’re going over a mountain range. In a diesel truck, you actually don’t capture the energy of height or potential energy.” For a century, freight has fought gravity twice on every mountain. A diesel truck burns thousands of dollars in fuel clawing its way to the peak. It arrives at the summit loaded with enormous gravitational potential energy. And what does it do with that energy? It throws it away as heat. Musk: “You have to actually spend a lot of money on expensive brakes going down the other side so you don’t run out of control.” Diesel burns twice. Fuel going up. Hardware coming down. A century of logistics, and the descent was never anything but a cost to be survived. The Tesla Semi doesn’t survive the descent. It harvests it. Musk: “An electric semi truck is able to recapture the gravitational potential energy and in fact puts the energy back in the pack.” Regenerative braking doesn’t just slow the truck. It converts 80,000 pounds of downhill momentum into raw electricity flowing back into the battery. The mountain stops being an obstacle. It becomes a power plant. Here is the thermodynamic reality the market is missing. Diesel is closed on the descent. There is no version of a combustion engine that turns downhill momentum back into liquid fuel. It is structurally impossible. Electric is open in both directions. The same system that spends energy to climb gets paid on the way down. Wall Street keeps pricing the Tesla Semi on a cost-per-mile comparison. Kilowatts versus gallons. They are solving the wrong equation. You cannot win a price war against a machine that bills the planet for its own fuel.
