Most athletes only think of “strength” as what they do under a barbell.

But the forces your body encounters in sprinting and jumping are far greater than anything in the weight room.

Here’s why

- A squat is controlled force against a bar
- Sprinting & jumping are collisions

A squat is controlled force against a bar
Sprinting and jumping are collisions with the ground
Gravity, momentum, tendon contribution, ground reaction all stack together
That’s why peak forces reach 5x, 10x, even 20x bodyweight, far beyond ones squat max.

This is also why sprinting and jumping naturally overload the system. As you get faster and more skilled, the forces keep increasing.

If you want the full breakdown, what creates speed, how to train it, and how to apply this science, that’s exactly what I cover in Speed Kills.
