The OhJaw Workouts
What is a mastiCore™ workout?
Think of mastiCore™ as heavy weightlifting for your face. It is a targeted, high-resistance mastication (chewing) workout designed specifically to engage and hypertrophy the masseter muscles- the powerful muscles at the back of your jaw. By applying consistent, progressive resistance, mastiCore™ helps sculpt a sharper, wider, and more defined jawline while improving overall facial muscle tone.
What is a lingoKinetics™ workout?
While mastiCore™ builds the sides of your jaw, lingoKinetics™ tones everything underneath. This workout focuses on tongue posture and functional movement. By training your tongue to rest properly against the roof of your mouth and engaging the submental muscles (the area under the chin), lingoKinetics™ helps eliminate the appearance of a double chin, promotes better breathing habits, and sharpens your forward facial profile.
How do I start my mastiCore™ chewing exercises?
Just like any gym routine, you need to start smart and build endurance. We recommend beginning with a lighter resistance level to allow your masseter muscles and temporomandibular joint (TMJ) to adapt. Start with short, focused sets of 5 to 10 minutes a day, every other day. As your facial strength increases, you can gradually upgrade to tougher resistance levels and longer workout sessions.
Health, Safety & Materials
Doctors usually advise against chewing gum. Why do you encourage intensive chewing?
This is the most important distinction: OhJaw is not regular chewing gum; it is a dedicated fitness tool. Regular gum is loaded with sugars or artificial sweeteners, breaks down easily, and is often chewed mindlessly for hours, which can cause joint strain. OhJaw, on the other hand, is built for short, intense, and deliberate workout sessions. You chew it with intention for 10-15 minutes to fatigue the muscle, just like lifting weights, and then you stop and let the muscle recover and grow.
I am worried about free micro-plastics settling in my body. Have your products been tested?
Your safety is our absolute priority. We rigorously test our materials to ensure they meet the highest health standards. OhJaw products have undergone extensive endurance chewing tests. Even after 8+ hours of continuous, high-pressure chewing, there was zero degradation found in the quality or structure of the gum. There is no breakdown and no micro-plastics released into your system- just pure, safe, and durable resistance.
How do I clean and store my OhJaw gum?
Hygiene is crucial for your face gym routine. After each workout session, simply rinse your OhJaw gum under warm running water. Let it air dry completely and store it safely in the provided OhJaw carrying case to keep it fresh and ready for your next set.
