Shoulder stabilizers and core stabilizers are put to work when we place one hand in the center of your Core-Tex Sit. Controlling and stabilizing the responsive motion of Core-Tex Sit adds an entirely new experience to this traditional strengthening exercise.
Ordinary planks are boring and can have diminishing returns. A plank with your hand on Core-Tex Sit keeps it interesting and has ongoing value due to the variability of the challenges Core-Tex Sit will present to your core stabilizers. It's going to a little different every time, keeping the benefits coming.
