Saying you got hurt because your hamstrings are “weak” is reductive.
Injuries aren’t that simple…they’re complex, multifactorial, and usually come down to timing, recovery, and mechanics.
You can have “strong” hamstrings and still get hurt if fatigue changes how you move,

if recovery doesn’t match workload, or if your mechanics are inefficient.
The weight room builds capacity, stronger tissue, longer fascicles, higher force potential.
But sprinting and reactive drills teach your hamstrings how to use that capacity, how to stabilize before

contact, coordinate with the glutes and quads, & recycle energy at real high velocities.
And none of it matters if recovery isn’t built into the plan.
Too much high-speed work without enough restoration throws off rhythm and timing and that’s when tissue load exceeds capacity.

That’s why Speed Kills includes an entire section on the role of the hamstrings in sprinting, how to prepare them, how to return to running after a strain, and how to build the resilience needed to stay fast and healthy.
It’s not just theory, it’s a full 8-week high-speed
