This kit combines a pre-sized Pop N Go unit and a customizable small Custom Fit piece so you can progress through resistance levels and tailor the fit to your bite. Designed for hands-free use, both devices are made in the USA and include carrying cases, bite strips, and access to the free Jawzrsize app for guided sessions and habit tracking.
The Jawzrsize pair is built for short, repeatable sessions you can do anywhere — at home, at the office, or between errands. The compact units let you add facial resistance training without a big time commitment, and the app helps you schedule and log workouts.
Consistent resistance chewing targets the muscles around the jawline, lower face, and upper neck, which may increase muscle engagement and endurance over time. Results depend on frequency, intensity, and individual anatomy; use progressively and follow app guidance for structured progression.
Insert the unit between the teeth and bite with controlled rhythm according to the app or printed guidance. Start with short sessions and increase duration gradually; replace bite strips when worn and keep pieces clean to maintain hygiene. If you have dental work or TMJ concerns, consult your dental professional before beginning.
This bundle ships with both a Large Pop N Go and a Small Custom Fit in green, plus storage and fit accessories so you can start training immediately and keep components hygienic. The app provides guided workouts and community features to maintain motivation.
Who is this for? The Jawzrsize Pop N Go & Custom Fit bundle is suited to adults who want a portable way to add facial resistance training to their lifestyle. It’s intended for people seeking an at-home, equipment-light option to engage jaw and lower-face muscles, with adjustable fit and app-guided progression. Not recommended for children; consult dental or medical professionals if you have implants, recent oral surgery, severe dental concerns, or chronic jaw pain before starting any new chewing regimen.
Q: How often should I use Jawzrsize for best results?
A: Start with short daily sessions (a few minutes) and increase gradually. Consistency matters—aim for several short sessions per week and use the app to track progress.
Q: Is this bundle safe with dental work or TMJ issues?
A: If you have dental restorations, orthodontics, or TMJ concerns, consult your dentist or doctor before starting Jawzrsize to ensure safety.
