Built for your sport. RS1 is built for athletes and active people who want performance, stability, and protection during training — without anything slowing them down. Whether you're lifting, competing, or just staying active — RS1 works from the moment you put it in. Why RS1? Unlike standard mouthguards designed only for impact protection, RS1 is engineered to optimize jaw position under load — unlocking strength, airflow, and full-body stability during athletic output. Key Benefits No molding required — ready to use instantly Immediate performance impact from first use Opens airway for better oxygen under load Converts jaw tension into raw power output Protects teeth during high-intensity activity Supports full-body stability through jaw alignment Perfect For Powerlifting & strength training Bodybuilding & gym sessions CrossFit & HIIT Combat sports & martial arts Team sports & court sports Yoga, spin, and group fitness classes Any activity where you move, breathe, and push hard How It Feels RS1 is designed to feel purposeful, not intrusive — a subtle shift in jaw position that your body immediately responds to, so you can focus entirely on your performance. Performance Benefits Jaw spacing supports full-body posture and stability Reduced muscle tension means less wasted energy Airway stays open so you breathe harder, fatigue slower Clenching surface channels jaw force into output, not damage How It Works RS1 creates precise spacing between your upper and lower jaw — decompressing the TMJ, opening your airway, and activating stabilizing muscles from head to toe. Four mechanisms working together, measured at the jaw, felt through the whole kinetic chain.
