Full body tension is the difference between a mediocre hold and a rock-solid one. It's not just your core—it's your glutes, your quads, your lats, your grip. Everything contracts simultaneously to create a single, immovable unit. This is essential for planches, front levers, handstands, and any straight-body skill. Practice it in hollow body holds, planks, and handstands. Learn to turn it on and off at will. The best athletes don't just have strong muscles—they have total control over their tension.
