Set up on a low box or platform—shin-height or about knee-height depending on your comfort. Stand at the edge, then step off and land on both feet simultaneously. This is where the work happens: land quietly on the balls of your feet, then roll through to your full foot as your knees and hips absorb the impact. Your landing is soft and controlled, not explosive. Your torso stays upright and your arms balance you. Once you've landed and stabilized, step back and reset. Don't try to rebound immediately until you've built comfort with the landing pattern itself.
