Waterloo Park pairs two very different kinds of release in one free evening session. Instructor Alia J Khan starts with an upbeat yoga flow driven by a playful 1990s playlist, then eases everyone down for a harmonic sound bath built from crystal bowls and voice. The shift from movement to stillness gives beginners and regular practitioners room to participate at their own pace. Bring a mat and a friend for an hour that feels part fitness class, part downtown reset.
