Runners: it's almost never your calf.
Calf tightness that keeps coming back is usually a glute problem.
Here's the test: stand on one leg and slowly lower into a quarter squat. If your knee dives inward or your hip drops, your glute medius isn't doing its job — and your lower leg is absorbing the difference. That's why the calf keeps tightening. You're stretching a symptom, not solving the cause.
The fix:
Side-lying leg raises, 15 a side, slow, before you run
Focus on the top glute — the one on the side, not behind you
Do it consistently for two weeks before you judge it
Not sexy. Very effective.
