Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The field of invention generally relates to an exercise device focusing on the core and leg muscles. More specifically, the field of invention relates to an exercise device for sports such as alpine skiing and tennis, and for the physical therapy benefits on a rebounding device.

2. Description of Related Art

The present invention generally relates to an exercise device with a compressible element and a platform which provides multiple benefits over the prior art.

The benefits of jumping and bouncing as part of an exercise routine are well-known. The gravitational forces acting upon the body influence hundreds of muscles and body cells simultaneously and heighten a person's balance and equilibrium. These exercise routines provide tremendous core and leg exercises as well as cardiovascular benefits. It is well known in the art that jumping and bouncing back and forth and from side to side between inclined trampolines is a beneficial exercise for skiing and other sports.

Unfortunately, inclined trampolines suffer the disadvantages of having an outer perimeter mass of noisy springs or cords attached to a rigid frame that adds considerable girth and is uncomfortable and harmful when struck during an unintended misstep or fall. This outer frame is a known hazard to experienced trampoline users. Another disadvantage of the traditional mini trampoline is a negative pronation of the ankle joints due to the dimpling or curvature of the stretched trampoline fabric acting upon the foot when fully depressed.

The present invention includes a compressible element under a platform which has the advantage of eliminating the space between the springs or cords attached to a rigid frame and does not result in negative pronation of the ankles joints. The platform provides more support for the ankles than the stretched trampoline fabric.

Further the present invention provides a significant amount of versatility and personalization. The user can choose the compressive force of the compressible element, increase the angle of a forward tilt and can optionally set the distance between a first and second platform.

SUMMARY OF THE INVENTION

Preferred embodiments of the present invention provide for multiple embodiments of an exercise device generally having a compressible element and a platform disposed over the compressible element for use by for example, sports enthusiasts, such as skiing and tennis enthusiasts, and for those engaging in physical therapy.

For example, an exemplary embodiment of the present invention provides a first compressible element; a second compressible element; a first platform disposed over the first compressible element, the first platform having an interior portion and an exterior portion, wherein the first platform is downwardly inclined towards the interior portion; and a second platform disposed over the second compressible element, the second platform having an interior portion and an exterior portion, wherein the second platform is downwardly inclined towards the interior portion of the second platform and the interior portion of the second platform is adjacent to the inner edge of the first platform.
