Three resistance levels. One complete jaw training system. Built for athletes who don't skip anything.
The masseter is one of the strongest muscles in your body. Most people never train it. The Masso 3-piece set gives you a complete progression from beginner to advanced — just like any other training program.
Start here. Build the foundation. Train the masseter muscle with controlled, consistent reps. Ideal for the first two weeks of your program.
Step up when the 40lb feels comfortable. Feel the difference immediately. Your jaw muscles adapt fast — this is where real progress happens.
The hardest in the set. Not everyone gets here on day one. Work up to it and you'll know the difference.
Safe for daily use. BPA-free, odorless, built to last through your training.
40lb to 60lb. Train like a program — not just a product.
Fits in any gym bag or pocket. Train anywhere — gym, office, car, beach.
Short, consistent sessions. Results in 30 days when you stay consistent.
Begin with the light resistance. 3 sets of 30 reps, 10–15 minutes per day. Give your masseter muscle time to adapt.
When the current level feels comfortable, step up. 40 → 50 → 60 LB. The same way you add weight in the gym.
Muscle growth requires consistency. Daily training sessions over 30 days is where you'll see and feel the real change.
