Hot Pilates is a mat Pilates class performed in a heated room, typically 85–100°F. The heat warms your muscles before you even start moving, allowing deeper engagement, greater flexibility, and increased calorie burn compared to room-temperature Pilates. If you've done Pilates before, hot Pilates will feel familiar but more intense. If you're new to Pilates entirely, the heated format is a surprisingly good place to start — warm muscles respond better to the controlled, precise movements that define Pilates.
