Before trampolines, the only way to increase the elevation of a jump was to piggyback Michael Jordan. Bound into glory with today's Groupon to Sky High Sports in Bellevue. Choose between the following options:

• For $9, you get two hours of jump time, Monday–Thursday (up to a $19 value).
• For $11, you get two hours of jump time, Friday–Sunday (a $22 value).

Blanketed in wall-to-wall trampolines, Sky High Sports delights barefooted fun-seekers with springy terrain and an exclusive court for jumpers 8 and younger. Guests can hone front flips, back flips, and belly flops during intense free-bounce sessions. Each trampoline comes loaded with a specially designed, spring-loaded frame and thick, 2-inch safety pads that grant patrons a landing cushier than a corner office at a marshmallow factory. Stuffed with blocks of spongy, body-molding material, a foam pit dares treasure-seekers to fling themselves in or scour its depths for the lost contents of bygone pockets.

Pintsize aerialist posses can safely practice their synchronized salchows on 360 degrees of trampoline walls while court supervisors watch from the sidelines and bequeath hard-earned praise with oversize scorecards. Though not included in this Groupon, Sky High offers AIRobics fitness classes and monthly dodgeball tournaments to help jumpers explore the outermost stratospheres of trampoline possibilities.
