About
Slow is strong.
Stillwater began with one reformer and a belief that movement should feel like a reset, not a race. Today we teach small groups and private sessions in a studio designed to quiet the noise. Every class is led, watched, and adjusted by a teacher who knows your name and your knees.

Loved by the people who show up.
“I came in with a cranky back and left with a practice. Lena watches like a hawk, in the best way.”
“The calmest hour of my week. I actually look forward to the reminder that says it's time.”
“Small classes mean I never get lost. They know my name and what I worked on last time.”
