Begin by doing the back handspring on a large trampoline, which will help you jump higher and master the backward jumping technique before you move to a stable surface.
Dip down by flexing your hips and knees to prepare to jump. Swing your arms behind you so that they’re loaded to eventually swing upward.
Explode into a hop by pushing and extending your legs and swing your arms forward and up over your head. Jump backward, rather than upward, by arching your back slightly and looking backward toward the ground. This is the most challenging step to master, so if you’re scared to jump backward, start by practicing the move and fall on your back onto a soft mat or couch until you’re comfortable.
Swing your legs upward and plant your hands on the floor. At this point you’ll be in a position similar to a handstand, except that your back will still be slightly arched, with your straight legs trailing slightly behind your torso.
Push off the floor with your hands and continue to swing your legs over your body to keep rotational momentum. Bring your feet to the ground and lift your hands up off the ground to pop up into a full standing position and complete the full back handspring.
