For the best results, we recommend starting at Level 1, and working your way up to Level 4.
Each Level provides an increase in resistance to your bite, so you can keep making progress until you've reached your goal. Once you reach your goal, make sure to do a few maintenance sessions a week so that you don't lose your progress.
Jawzrsize Works Over 57 Muscles through a repeated "biting" motion. Simply place it in your mouth and start repping (each bite is a rep).
If you are looking to slim, tone and tighten your face and neck, do a few "burnout sessions", where you rep until you simply can't anymore.
If you are looking to strengthen and build muscle in your jaw, switch it up and focus on "time under tension", where you bite down, hold, and slowly release your bite. A few reps goes a long way!
Each Level provides an increase in resistance to your bite, so you can keep making progress until you've reached your goal. Once you reach your goal, make sure to do a few maintenance sessions a week so that you don't lose your progress.
