👉 If your outside knee pain keeps showing up, test this: Side Plank Star Hold. If it breaks you… you’ve found the leak.
No fluff — this is a quick screen for lateral hip + trunk capacity (the stuff that keeps your femur from wobbling and your knee from getting dragged into chaos when you’re tired).
✅ How to test it (properly)
• Set up in a side plank (elbow under shoulder)
• Top leg lifts into a “star” (hip abduction)
• Keep ribs stacked, pelvis level, bottom hip off the floor
🔍 What you’re looking for
If you get:
• pelvis dropping
• top leg shaking / cramping instantly
• trunk rotating forward
• knee pain flaring or you can’t keep form…
…that’s not “weakness shame” — that’s a capacity clue.
Why it matters for outside knee pain
When lateral hip + trunk control drops, your body often borrows stability from the knee (hello ITB irritation / lateral knee pain), especially with:
• downhills
• speed work
• cambered roads
• fatigue in the last 10–20 minutes
🛠️ What to do with it
Don’t just test it — train it:
• 3–4x/week
• Progress by adding slow top-leg pulses or longer holds
• Keep symptoms in a workable zone (mild is ok, worse-for-24h is not)
