Why Hip-to-Shoulder Separation is the #1 Key to Bat Speed
Brendan Rodgers
MLB Gold Glover · #3 Overall Pick
Every elite hitter I've faced — and every coach who's worked with me from high school through the big leagues — talks about one thing: separation. Here's what it actually means and how to train it.
What Is Hip-to-Shoulder Separation?
Hip-to-shoulder separation is the rotational difference between your hips and your shoulders at the moment your front foot lands. The hips fire first, the shoulders follow — and that gap in between is where bat speed is generated. Think of it like a rubber band: the more you stretch it, the more snap you get.
Why Most Youth Hitters Don't Have It
The most common mistake I see in hitters ages 8–18 is that they rotate everything together — hips and shoulders moving as one unit. It feels powerful, but it kills leverage. The barrel drags, the swing path gets steep, and you lose 15–20 mph of exit velocity before the ball even leaves the pitcher's hand.
How We Train It at The Dojo
We use a combination of dry tee work, resistance band rotations, and HitTrax feedback to isolate the hip load and force separation. Brendan works athletes one-on-one on feel — because you can't just think your way into it. You have to feel the stretch and release, over and over, until it's automatic.
