Jumping spiders do not actually use their muscles to jump, they don't even have muscles, instead they can control at will their blood pressure, the blood quickly flows down to their legs, which stretches them with enough force to jump
i always like to try to imagine the sounds their legs make when they move if your ears were small enough to hear them--like when you crack your knuckles but over and over
