Everyone loves the Vertical Jump, but how meaningful is it?

Stefan Holm, Olympic champion, reportedly had just a 23-inch vertical and still cleared 2.40m, over 94 inches. Nearly 70 inches higher than his vert.

Why? Because a standing vertical isn’t the same as a high jump.

One is bilateral, static, and more strength dominant. The other is unilateral, velocity driven, and highly technical.

Holm understood that. He trained a handful of basic lifts, tons of plyometrics and jumps, and then practiced his event relentlessly. Consistency and

specificity.

That’s the lesson…don’t confuse tests with performance. What matters is how training transfers to the actual sport.

This is exactly why I wrote Speed Kills. I break down how to set up sprint training, what really drives speed, how to blend strength and sprint

work, where plyometrics fit, resisted sprints, overspeed, programming strategies, even what to do for different athletes like a 400m runner.

It’s about cutting through the noise and chasing the qualities that matter most for performance.

If you want to stop guessing, understand biomechanics, and build a system for speed, Speed Kills is where to start.
