Introduction
Every year at the NFL Combine
👉 the same thing happens
Elite athletes—stronger, faster, and more prepared than ever—step up to run the 40-yard dash
👉 expecting their best performance
👉 And every year…
👉 some of them don’t deliver
Despite:
- elite coaching
- advanced programs
- months of preparation
👉 their speed doesn’t improve
👉 and sometimes… it gets worse
👉 So what’s really happening?
👉 Want to understand how speed is actually developed as a system?
➡️ Run Faster with Isometric Training
⚠️ The Pattern No One Talks About
These athletes didn’t fail because they didn’t train hard enough
👉 In fact:
- they got stronger
- they improved conditioning
- they followed structured programs
👉 But their speed didn’t improve
💥 That’s not random
👉 it’s a pattern
➡️ Why Most Speed Training Programs Don’t Work
🧠 What Most “Speed Training” Actually Develops
Leading up to the combine, many athletes focus on:
- resisted sprinting
- weight training
- high-repetition drills
- conditioning work
👉 These methods can improve fitness
👉 But they primarily develop:
👉 strength and conditioning
👉 not true speed
➡️ Why Strength Alone Won’t Make You Faster
❗ The Real Issue: Strength Imbalance
Most programs heavily develop:
- hip extensors (glutes, hamstrings)
- quadriceps
- calves
👉 These dominate the push phase
👉 But they neglect:
- hip flexors
- swing phase
- coordination
💥 This creates a strength imbalance
👉 One part of the system becomes dominant
👉 while another becomes the limiting factor
👉 And when that happens:
👉 the system cannot operate at a higher level
💥 Your speed is limited by your weakest link
👉 For a complete breakdown of how speed really works:
➡️ How to Run Faster: The Complete Guide to Speed, Power, and Performance
🔑 The Hidden Limitation: The Swing Phase
Speed is not just about pushing harder
👉 It’s about how fast you can cycle your legs
➡️ How to Increase Stride Rate (Without Overtraining)
👉 That movement is driven by:
👉 the hip flexors
👉 These muscles:
- bring the leg forward
- control recovery
- influence stride speed
👉 If they are underdeveloped:
👉 your speed is capped
👉 no matter how strong you are
➡️ Hip Flexors for Running Speed
🔄 Speed Is a System—Not a Single Attribute
One of the biggest misconceptions:
👉 strength = speed
👉 But speed doesn’t work that way
👉 Speed is a system:
- push phase → force
- swing phase → speed
- return phase → timing
👉 If one part is underdeveloped
👉 the entire system is limited
➡️ Push Phase vs Swing Phase in Running
⚡ Why Athletes Plateau—or Get Slower
When athletes keep training:
- the same muscles
- the same way
- with the same methods
👉 they eventually hit a limit
At that point:
- strength gains slow
- added mass may reduce efficiency
- coordination doesn’t improve
👉 And speed stalls—or declines
👉 This is why some athletes run slower at the combine
🧩 What’s Missing From Most Training
Most programs build:
- strength
- endurance
- conditioning
👉 But neglect:
- coordination
- timing
- muscle response
👉 These are what actually determine speed
➡️ How Coordination Affects Running Speed
🚀 A Smarter Approach to Speed Development
To improve speed, training must go beyond strength
👉 It must train your body to:
- react
- adjust
- stabilize
- coordinate
👉 This is where system-based training becomes powerful
➡️ Isometric Training for Speed
➡️ Resistance Bands for Speed
🏁 Conclusion: Why Speed Doesn’t Improve
When athletes fail to improve their 40 time
👉 it’s rarely effort
👉 it’s incomplete development
They’ve built:
👉 strength
👉 but not the system required for speed
💥 And without that system
👉 strength cannot fully translate
🔥 What This Means for You
If you want to run faster:
👉 don’t just train harder
👉 train the entire system
Focus on:
- eliminating strength imbalance
- improving coordination
- developing all phases
💥 Because speed is not just force
👉 it’s how efficiently your system works together

❓ Frequently Asked Questions
Why do athletes get slower after training hard?
Because their training often overemphasizes strength while neglecting coordination and full-system movement.
Why is the 40-yard dash affected by training?
Because speed depends on how your body moves and coordinates—not just how strong you are.
Do stronger athletes always run faster?
No, strength helps, but without proper coordination and muscle response, it won’t translate into speed.
What is the biggest mistake in speed training?
Focusing too much on strength and not enough on coordination, timing, and system development.
How can I improve my sprint speed effectively?
By training your body to respond quickly, coordinating all phases of movement, and addressing weak links like the swing phase.
