Double-mini is a relatively new form of trampolining involving running down a track (like a gymnastics vault), and then bouncing on a specially designed trampoline having two “bounce areas”, one slightly sloped at the front and a second flat area directly attached to it, followed by a padded landing mat.
Athletes must complete two moves during their pass, landing cleanly on their feet between moves. They may perform these two moves in any of the three opportunities, while mounting, while traversing to the second area, or while leaving to land on the mat. (Most routines take advantage of the last two bounces as they will typically get more height and hence more time to complete their skills).
