Our Classes
Stronger Bodies, Better Lives
Strong
Our flagship class fuses strength training with bursts of high-intensity movement to build, strengthen, and energize body and mind. Each session alternates between total-body work on the machine and dynamic, muscle-focused floor exercises with dumbbells. From core-crushing ab work to glute-focused sets, every class maximizes output and develops functional strength. Expect a thoughtfully programmed balance of power, pace, and control - all in a vibrant studio that keeps you motivated from start to finish. Whether you’re new or leveling up, this class adapts to your level while pushing you toward progress, one endorphin-filled session at a time.
Pilates-Inspired Deep Muscle Workout
Sculpt
Sculpt is a strength and stability class that blends Pilates-inspired principles with deep muscle activation. This low-impact, high-focus workout targets both major muscle groups and often-overlooked stabilizers - sculpting, strengthening, and aligning body and mind. Expect slow, deliberate movements with emphasis on form, breath, and mind-to-muscle connection to improve posture, enhance balance, and build body awareness. Each session closes with mindful breathwork to calm the nervous system and restore clarity - leaving you centered, strong, and recharged.
