Instructor
Haleigh MartherusA functional, circuit-style training program designed to push your limits and build metabolic conditioning. Moving through structured workout zones, this high-energy class uses varied exercises to maximize strength, power, and athletic endurance.
What to Expect
A fast-paced circuit using functional equipment like kettlebells, dumbbells, resistance bands, and bodyweight drills. The layout is station-based, keeping your heart rate elevated through explosive intervals and recovery periods.
Member Feedback
“Ceremony is tough but incredibly engaging. The circuit structure means you are constantly moving to a new station, which keeps the workout interesting. It is challenging, but you can scale every single exercise.”
Pro Tip
Wear supportive, flat-soled cross-training shoes for stability. Bring water, prepare for high-impact movements, and arrive early to hear the instructor explain the circuit layout.
