I tense my calves and massage the gastrocnemius and Achilles' tendon.
I also do ankle circles to feel for knots/muscle tightness. And I do all this in 2 inch split shorts when I'm sitting down in public or resting.
I've had married men comment on my legs with their wives: those are some damn beautiful legs
And when I do ankle circles, I notice other women mirror my body language and start stretching their legs too.
