WHY RUNNERS GET INJURED
(And why it’s usually not “too much running”)
Most running injuries don’t happen because people run too much.
They happen because people run without a foundation.
Running is a skill — and it exposes weaknesses.
⸻
1️⃣ Running Builds Endurance — Not the Foundation
Running trains:
• Heart
• Lungs
It does not train:
• Core stability
• Hip and glute strength
• Pelvic control
• Thoracic mobility
• Foot and lower-leg strength
• Posture under load
👉 You can be cardio fit but structurally unprepared.
That’s the most common reason runners get hurt.
⸻
2️⃣ Problems Start Long Before Pain Shows Up
Most injured runners have some version of:
• Tight hip flexors
• Weak or delayed glutes
• Poor core control
• Stiff upper back
• Overworked calves
• Collapsing foot mechanics
• Shortened, compensatory stride
Pain isn’t random.
It’s the body signaling imbalance.
⸻
3️⃣ Running More Doesn’t Fix Running Injuries
If an imbalance caused the problem,
more mileage just adds stress to the same weak links.
You don’t fix running injuries by:
• running through pain
• stretching the sore spot
• “getting tougher”
You fix them by addressing what running doesn’t train.
⸻
4️⃣ Most Running Injuries Are Preventable
When runners restore:
✓ Mobility (hips, upper back, ankles)
✓ Activation (glutes, deep core, posture muscles)
✓ Stability (single-leg control, pelvis)
✓ Strength (hips, core, lower leg)
Running becomes:
• smoother
• more efficient
• more durable
And pain usually fades.
⸻
The MOTUS Takeaway
You don’t need to stop running.
You need to support running.
Build the foundation.
Then run on top of it.
