Of course there are differences between athletes.
Different sports. Different anthropometrics.
Different strength and elastic profiles.
But if all we ever focus on is what’s different, we miss the similarities
The athletes who accelerate well, across sports, often show us the

same themes over and over again.
That’s because physics and biomechanics impose constraints on how the body can move forward quickly and efficiently.
We don’t get to opt out of those rules.
Our job as coaches isn’t to force identical technique. It’s to recognize the common

solutions, understand why they work, and then apply them within the context of the individual athlete.
That means
• understanding movement
• understanding the athlete
• understanding the physical abilities that underpin acceleration
• and understanding how to actually

teach and train it
That’s exactly why I built Speed Kills.
Speed Kills is a full breakdown of why speed works the way it does and how to train it intelligently.
Inside you’ll find
• acceleration and max velocity mechanics
• how to coach and progress sprinting
• how

plyometrics support speed development
• how strength training fits (and where it doesn’t)
• resisted sprinting, eccentrics, isometrics, and stiffness
• fitness and conditioning in the context of speed
• and a complete, structured speed development framework

If you care about helping athletes accelerate faster, safer, and more efficiently, regardless of sport, this is the blueprint.
