Thank you very much for always watching.
A demonstration experiment was conducted to verify the effectiveness of the SUPER HERO'S undershirt.
Twenty-one high school baseball players were measured from September 1, 2022 to September 30, 2022. Using a grip strength meter, we compared the values before and after wearing the undershirt.
You can see the results. Most of the ball children have increased their grip! The moment you put on the undershirt, you can feel the improvement in your physical ability!
