X3 is a variable resistance system, which makes it clearly distinct from regular weights. When you exercise with regular weights the amount of weight you are lifting is constant. With X3, your muscles encounter less load in weak ranges of motion, but then that load increases in stronger ranges of motion, providing a much greater exercise benefit with less risk.
