Better than holding plates with a t-shirt
From a Fighters/medical student perspective.
Get it.
Drop the the old school boxing jaw exercises and grab this. Don’t listen to the reviews about your teeth. You bite down on shirts and hold plates. What’s worse?
Read up, you can target the muscles that you want without overdoing it... be smart about it. It’s your jaw, not your legs.
