You sit in front of the mirror, look at your face and think: «my jaw could be sharper.» You are not alone in that. While most people focus on abs, legs and glutes, the jaw stays blank in the training plan – even though some of the strongest muscles in the body sit there. That is where the chewing trainer comes in. 🏋️
What a chewing trainer actually is
A chewing trainer is a small piece of firm silicone that you bite down on. It creates resistance – more than any chewing gum – and the chewing muscles have to work against it. The principle is the same as a dumbbell: resistance, repetition, rest. The Kurandero Jawline Trainer is made of BPA-free food-grade silicone and fits in any pocket.
Which muscles are involved
When you bite down, the masseter does most of the work – the chewing muscle you can feel at the side of your jaw when you clench – along with the temporalis at the temple. Both are among the strongest muscles we have. How far training visibly changes the shape of a face depends heavily on bone structure and body fat – no device changes that. To be honest: the jawline you see on Instagram is mostly genetics plus lighting, not training. 😉
How to use it
- 🦷 Place the trainer between the molars, not the front teeth.
- ⏱ Short sessions, a few minutes per side. More is not better here.
- 🎯 Regularly rather than at length. As with any muscle, consistency counts – and so does the rest in between.
- 🧼 Clean it with warm water after every use.
When to leave it alone
This is the part most sellers leave out. If you have jaw joint problems – clicking, pain when chewing, morning tension – or if you grind your teeth at night, additional strength training for exactly those muscles is not a good idea. The same applies with braces, implants, crowns and bridges. If in doubt, clear it with your dentist before you start. And if something hurts during training: stop, don't push through. 🩺
In short
The chewing trainer is no miracle worker and turns nobody into a different person overnight. It is what it is: a simple resistance device for muscles nobody else trains – cheap, small, and done in a few minutes a day. If your jaw is healthy, there is nothing against giving it a try.
