• Stand on Vertimax with bungee cords attached
• Lower to specified depth and explode into jump
• Land naturally, reset, and repeat
• For explosive jumps, immediately jump again upon landing

The wisdom: “The Vertimax is a great way to add resistance to jumps so guys become more powerful and explosive. If a Vertimax isn’t available, put your weight belt around your waist and attach elastic cords to it. Have partners stand on the ends of the cords to provide resistance.”
