To do Snowboard Hops, start standing with your feet parallel and about shoulder-width apart. Face toward one foot, keeping your feet parallel and then step your back foot slightly forward so your stance is slightly staggered.
Then squat down, pushing your butt back as you reach the same arm as the foot in front down outside your front toe. You can hinge over at the hips, but do not let your core collapse and simply lean forward.
Then explode up off the ground, lifting your hand as you rotate forward and then to face the other way with your body. When you land, your back foot should be in front and your front foot should be in back, slightly staggered forward.
Land and squat back down, dropping your front arm down to touch the ground outside your front toe. Then jump back up and rotate back to face the way you started.
Beginners may not sink as low or jump as high. They may also do more of a “step” to switch than a full jump. Move quickly and make sure to bend your knees and sink down as you land. Also make sure your heels come down as you squat down. Keep your back flat even as you hinge over to touch the ground.
