Why Do I Get Cramp?
(And why stretching isn’t always the answer…)
If you regularly get cramp in your calves, hamstrings or feet, you’ve probably been told:
👉 “You’re dehydrated.”
👉 “You need more magnesium.”
👉 “Just stretch it out.”
Sometimes that helps.
But very often… that’s not the real reason.
What’s Actually Happening?
Cramp is your nervous system overreacting.
It’s an involuntary muscle contraction — your muscle switches “on” and struggles to switch back “off”.
And this usually happens because of:
1️⃣ Fatigue
Tired muscles are more irritable.
If you’ve increased training, walked more than usual, or stood all day — your nervous system becomes more sensitive.
2️⃣ Poor load management
Sudden spikes in activity = higher cramp risk.
Your body likes gradual progression, not “weekend warrior” mode.
3️⃣ Reduced strength or conditioning
Weak muscles fatigue faster.
Fatigue increases the likelihood of cramping.
4️⃣ Electrolytes & hydration
Yes — this can be a factor.
But it’s rarely the only cause in otherwise healthy people.
The Corrective Approach…..
Instead of just stretching when cramp strikes, try this:
✔️ Build strength in the affected muscle
✔️ Improve overall conditioning
✔️ Increase load gradually
✔️ Stay hydrated
✔️ Prioritise recovery
For calf cramp specifically:
• Slow controlled calf raises
• Gradual walking/running progressions
• Strength through full range (not just stretching)
Important:
If you are getting frequent night cramps, cramp with very little activity, or cramp alongside other symptoms — it’s worth speaking to a healthcare professional to rule out underlying causes.
Cramp isn’t random.
It’s usually a sign your body is asking for better load management, strength, or recovery.
Treat the cause — not just the symptom 💚
