If you’ve ever tried to run faster, you’ve probably heard this:
👉 “Focus on your push.”
👉 “Drive harder into the ground.”
👉 “Generate more power.”
👉 And that advice isn’t wrong
💥 But it’s incomplete
⚡ The Problem With Traditional Coaching
Most training focuses on one thing:
👉 the push phase
That means:
- stronger glutes
- more powerful hamstrings
- more force into the ground
👉 all important
💥 But here’s what gets overlooked:
👉 the swing phase
🧠 What Actually Happens When You Run
Every step you take:
- one leg is producing force
- the other leg is moving forward
👉 these are not separate actions
💥 they happen at the same time
👉 while one leg drives, the other prepares the next step
🔥 The Missing Half of Speed
Most athletes develop the push phase
👉 but under-develop the swing phase
👉 That creates an imbalance
💥 And when the system is unbalanced:
👉 speed is limited
⚖️ The Balance Between Push and Swing
Running is not just about producing force
👉 it’s about how that force is balanced across the system
For maximum speed:
- the push phase must generate force
- the swing phase must match it
💥 Key idea:
👉 you can only produce as much usable force as your system can balance
👉 If the swing phase cannot keep up:
👉 the system reduces output
💥 And your speed is limited
📈 Raising the Level of Strength Balance
Strength balance is not fixed
👉 it exists at different levels
When you walk:
👉 both phases are balanced at a low level
When you jog:
👉 that level increases
When you run:
👉 it increases even more
💥 Speed improves as you raise the level of strength balance across the system
👉 But here’s the limiter:
👉 the system can only rise as high as its weakest link allows
💥 In many cases:
👉 that limiting factor is the swing phase
🚨 What Happens When the Swing Phase Is Weak
If the swing phase cannot match the push:
- the stride shuts down early
- the foot returns to the ground too quickly
- the system cannot stay in balance
- timing begins to break down
👉 Even if the push phase is strong
💥 The result:
👉 shorter stride
👉 reduced force per step
👉 reduced speed
🧠 Why Focusing Only on the Push Phase Stops Working
Many athletes build strength with:
- squats
- deadlifts
- leg presses
👉 and they get stronger
But over time:
👉 progress slows or stops
❗ Why?
👉 the push phase improves
👉 but the system cannot support a higher level
👉 the swing phase becomes the limiting factor
💥 So the system self-regulates:
👉 reducing total output
👉 to maintain balance
🔄 The Role of the Swing Phase
The swing phase does more than move your leg forward
👉 it helps:
- maintain stride length
- control timing
- balance the system
- prepare the next step
💥 It allows the system to support a higher level of output
👉 Without it:
👉 you cannot fully use your strength
⏱️ Timing: The Key That Connects Everything
Speed is not just about force
👉 it’s about when force is applied
❌ Common belief:
- push happens
- then swing
✅ Reality:
👉 both happen at the same time
💥 More importantly:
👉 they must reach peak force together
- push leg
- swing leg
- arms
👉 That is how speed is actually created when you run
⚖️ What Happens When Balance Is Off
Your body doesn’t fall apart
👉 it adjusts
💥 It acts like a self-regulating system
👉 reducing force output
👉 to maintain balance
👉 If the swing phase cannot match the push:
👉 the system scales everything down
💥 The result:
👉 less force
👉 less speed
🧠 How This Fits Into the Bigger Picture
Running speed comes from a complete system:
- push phase
- swing phase
- arm support
- timing
- strength balance
👉 all working together
💥 One leg produces force
💥 both arms support it
💥 the other leg balances the system
👉 all at the same time

🚀 What This Means for You
If you want to run faster:
❌ don’t focus only on the push phase
✅ continue your current training
👉 while improving:
- strength balance across the system
- the swing phase
- timing
💥 That’s what allows your system to rise to a higher level
❓ Frequently Asked Questions
What is the push phase in running?
It’s when your foot is on the ground producing force.
What is the swing phase?
It’s when your leg moves forward to prepare the next step.
Which phase matters more?
Neither—speed depends on how well they work together.
Why do athletes plateau?
Because one part of the system limits how high the whole system can rise.
Can improving the swing phase increase speed?
Yes. It allows the system to support higher levels of force.
🔥 Final Thought
Most athletes train the part they feel the most:
👉 the push
👉 but speed comes from something bigger
💥 it comes from how high your system can rise while staying balanced
