Sprinting is unique.
It shows up in almost every sport.
Acceleration, max velocity, chasing, separating, reacting.
Because of that, a lot of people assume sprinting just “takes care of itself.”
But in training, sprinting is still used as a general stimulus.

stimuli only create specific adaptations when they’re applied deliberately.
Just sprinting in practice doesn’t guarantee you’re:
- Expanding the alactic envelope
- Giving the hamstrings and hip flexors enough high speed exposure
- Training elasticity and stiffness at the

velocities that matter
- Improving mechanical efficiency
- Or even accumulating enough quality volume to adapt
If sprinting is done under fatigue, with unknown reps and distances, and no real intent or feedback, it’s not true/effective speed training.

That’s exactly what Speed Kills is built around.
It breaks down sprinting as:
- A physical quality
- A neurological quality
- And a skill that has to be trained with intent
You’ll see how I structure

sprint volumes, how I expose athletes to high velocity safely, how sprinting ties into hamstring health and elasticity, and how all of it fits inside a complete training week without burying athletes in fatigue.
