To freeze the one handed cartwheel you need to put your hand further away from your body than you’re used to. This will prevent your lower body from flipping over. The hand position will essentially block the path of the cartwheel. If you perform your Au Batido and you’re just flipping, doing a cartwheel essentially, then you’re hand placement was most likely wrong.
Kick your first leg over, close to your ear. Imagine kicking a target with it (like you would in capoeria). Spot forward where your kick would land OR forward like you would in B-Boying. Lock your hip in place and let only your legs travel.
