Hot take for runners:
If you skip core training, you’re basically trying to fire a cannon… from a canoe. 🚣♀️💥
Your legs might be strong.
Your VO₂ max might be impressive.
Your shoes might cost more than your weekly groceries.
But if your trunk can’t stabilise the force you’re producing, a big chunk of that power is leaking out like a cracked water bottle.
Here’s the spicy truth 🌶️:
When you run, your hips and legs generate force — but your core is the transmission that transfers it efficiently through your body.
Weak core =
• Energy leaks with every stride
• More trunk rotation and pelvic drop
• Less running economy
• More load on hips, knees, and lower back
Strong core =
• Better force transfer
• Improved cadence and posture
• Less wasted energy
• More speed for the same effort
Translation:
You might be leaving free performance gains on the table because you’d rather run another interval than do 8 minutes of planks.
Brutal.
The good news?
You don’t need an hour-long “ab day.”
Try this runner-friendly core circuit 2–3x/week:
✔️ Dead bugs
✔️ Side planks
✔️ Pallof press
✔️ Single-leg bridge
8–10 minutes. That’s it.
Your watch will think you got fitter.
Your legs will feel fresher.
And your future self at kilometre 18 will be very grateful.
Run lots. But stabilise the engine that powers it. 🏃♀️🔥
