A Pilates studio features several reformer machines in a row, each with a large black exercise ball mounted on the wall behind. People are using the machines, and their reflections are visible in the mirrors. Overhead, circular lights illuminate the room, highlighting the machines' white frames. The floor is a light-colored wood. An air conditioning unit is on the wall above the first exercise ball.
