FS8 is a fitness concept that combines Pilates, Tone, and Yoga into a low-impact, high-energy workout. It aims to strengthen both the body and mind by incorporating elements from these three modalities. FS8 is designed to be a full-body workout with a focus on functional strength, flexibility, and stability. The "8" in FS8 refers to the eight key elements that support strength: cardio, mobility, posture, coordination, resistance, mental health, balance, and flexibility.
