A miniature trampoline includes a frame having at least a pair of spaced apart upper frame members each having an upper front end and an upper rear end, respectively, the upper frame members being inclined toward the upper rear ends, respectively. A trampoline bed includes at least one planar surface and a pair of elongate side edges situated between the upper frame members and extending substantially between the upper rear ends and upper front ends of the pair of upper frame members, respectively. The trampoline includes a plurality of springs, each spring having a spring fastener coupled to a respective upper frame member and a bed fastener coupled to the trampoline bed proximate a side edge thereof, wherein the springs are spaced apart along the respective upper frame members, respectively, such that the trampoline bed is selectively held in tension between the upper frame members, respectively.

A hurdle has a supporting frame and two crossing rods. The two crossing rod each respectively employing a connecting joint, a spring, an engaging member, and a locking screw engageable with two opposing standing bars. The supporting frame includes the two standing bars and a horizontal aperture. The crossing rod has a hollow rod body, a soft protector jacketed onto the rod body, and a secure aperture disposed through an end of crossing rod. The connecting joint includes a hollow tubal structure with an axial hole, a connecting section with a smaller diameter is disposed at an end, a combining aperture disposed on the connecting section. An end of the spring is a hook end and another end is a screw stem having a threaded section and an inner threaded aperture, and the hook end of the spring is placed into the connecting joint through the axial hole.

A practice device for simulating a cheerleading stunt includes a frame that has a base plate and a top plate; a tubular shaft that extends between the base and top plates; a weight that is disposed in the tubular shaft; a spring that is disposed in the tubular shaft and that contacts and biases the weight; a shoe structure; and a mount that supports the shoe structure at one end thereof and that is constructed and arranged to be disposed within the tubular shaft with the spring disposed between the weight and the mount.
