Apply abdominal pressure to your inner muscles to charge up your power. Core Energy applies powerful abdominal pressure to the transverse abdominis, also known as the muscular corset, and the pelvis, awakening your source of power! The source of all movement is the transverse abdominis. The transverse abdominis, also known as the muscular corset, plays a vital role in maintaining body posture and supporting the core. Core Energy applies pressure to the inner core muscles, such as the transverse abdominis, through moderate tightening, increasing abdominal pressure. This instantly increases abdominal pressure and activates the inner muscles. This results in increased core contraction, not only increasing power but also making movements more agile and flexible. Energy Power Mesh: An astounding 3000 Kpa. Developed specifically for baseball, Energy Power Mesh is a six-layer power net with a maximum burst strength (500 Kpa), approximately 1.5 times that of standard innerwear. *The official baseball rules specify belt sizes and hardware, but do not specify belt fabric. Core Energy's Energy Power Mesh fabric can be used for belts. You can wear this jersey with confidence in any genre of baseball, including professional baseball, amateur baseball, high school baseball, junior high school baseball, and elementary school baseball, without having to comply with the rules.
