Stop treating sprinting like jogging. Your hamstrings don't pull because they're weak—they pull because your nervous system hasn't learned to operate at high speeds. The solution? Progressive exposure through drills that teach your foot to strike under your center of mass, not out in front. Start with bounce fire drills focusing on dorsiflexion and ankle mechanics before adding volume. Sprint training is neural training, and your brain needs thousands of ground contacts to coordinate properly.
Episode Overview
Elite speed coach Brian Kula breaks down the science of running mechanics, injury prevention, and athletic performance. He explains why most hamstring injuries stem from neural coordination issues rather than weakness, introduces his bounce fire training system, and reveals why exposure to speed—not just strength training—is critical for injury-proof sprinting.
Key Insights
Hamstring Injuries Are Neural, Not Structural
Most hamstring pulls occur because the nervous system can't relax the muscle after contraction at high speeds. Slow RDLs won't prepare you for sprinting because they don't train the energy system used during explosive movement. Progressive exposure to actual speed is the only way to bulletproof hamstrings.
The Reaching Problem Causes Most Running Injuries
When runners reach forward with their foot before it hits the ground (plantar flexion), they create massive forces on impact and put the hamstring in a stretched, vulnerable position. Instead, the foot should strike under the center of mass in dorsiflexion, allowing you to push rather than pull your body forward.
Recovery Is Neural, Not Just Physical
The central nervous system fatigues faster than muscles. High-level athletes often don't perceive fatigue, making objective measures like force plate data or grip strength critical. Charlie Francis's high-low system—alternating intense and light days—prevents neural burnout better than constant grinding.
Everyone Who Moves Is an Athlete
The distinction between 'fitness' and 'performance' training is artificial. A mother lifting weights uses similar movements to pro athletes—the difference is intensity and intent. This means general population clients should train with many of the same principles as elite performers.
Strength Without Speed Creates Injury Risk
A 600-pound deadlifter who never sprints is at higher injury risk than a deconditioned person because they can generate force without the neural coordination to control it. You need both the structural capacity and the nervous system training to handle high-velocity movements safely.
Notable Quotes
"That's why you pulled your hamstring. It wasn't because you're weak. Your brain hasn't had to operate like that. And it doesn't surprise me you did it on the second rep. That second rep your CNS is under fatigue and now you're asking it to go fast again and it goes haywire hamstring."
"I'll always say like, 'Hey, if my car broke down, would we pull it to the gas station or would we push it?' And they're like, 'We push it, coach.' Why? Well, because it's easier. So pushing, right, getting that foot under the center of mass and pushing the mass down the field, the track, whatever is more efficient than pulling."
"There isn't really an exercise in the weight room that you can do that takes care of the hamstrings. Exposures to speed is probably the most critical thing you need to do to bulletproof hamstrings."
"If you move, you're an athlete. I think we categorize like, you know, if mom goes to the gym, right, and she's doing athletic type movements, lifting weights, flexibility, mobility stuff, it's very similar in parallel to what some of the athletes are doing."
"With high level athletes that have really high output, more the more rest the better, right? more sleep, more days in between high intensity days."
Action Items
-
1
Practice Dorsiflexion During Ground Contact
Focus on keeping your foot in a loaded, dorsiflexed position when it strikes the ground. Avoid reaching forward with a plantar-flexed foot. This single cue reduces impact forces and protects against shin splints, patellar tendinitis, and hamstring strains.
-
2
Build Speed Tolerance Gradually
Start with bounce fire drills at low intensity, focusing on ankle mechanics and thousands of ground contacts. Progress through a matrix of drills addressing linear, lateral, and change-of-direction movements before attempting max-effort sprints. Volume and intensity must be micro-dosed.
-
3
Implement High-Low Training Cycles
After high-intensity training days, follow with lighter recovery days to allow nervous system recuperation. Use 4-week blocks alternating light, medium, and heavy weeks. Don't trust how you 'feel'—use objective measures like force plates or grip strength to guide programming.
-
4
Prioritize Tight Heel Recovery
After your foot strikes under your center of mass, immediately recover your heel tight to your hamstring rather than letting it swing out behind you. This positions your foot for a powerful next strike and reduces reliance on pulling motions that stress the hamstring.
