Abstract
An adjustable exercise device that includes one or more inclined riser blocks for readily elevating and inclining a platform to enable stepping and other exercises to be readily performed on an inclined platform. The inclined riser blocks may be matingly engageable with the bottom of the platform to elevate and incline the platform. The inclined riser block may include a top face matingly engageable with the bottom of the platform, a bottom face, and a central portion extending between the bottom and top faces and having a front and rear, the central portion increasing in thickness from the front to the rear. The top face extends at an incline.
Claims27
An adjustable aerobic exercise device comprising:
- a platform having a substantially flat top surface and a bottom, the platform configured to extend parallel to a horizontal support surface when disposed on the horizontal support surface;
- at least one inclined riser block with at least one interlocking surface matingly engageable with the bottom of the platform for elevating the platform above the horizontal support surface and inclining the platform relative to the horizontal support surface, the inclined riser block having a pair of sides, a top face extending at an incline from one side to the other side, and a bottom face, the top face of the inclined riser block matingly engageable with the bottom of the platform, the incline of the top face being closer to the bottom face at the one side than at the other side substantially the same as the incline of the platform when the top face is matingly engaged with the platform, and
- wherein when the platform is stably supported by at least one riser block it is configured to be used for performing aerobic stepping exercise, and
- wherein the platform has a width and a length, the inclined riser block is configured to incline the platform relative to the support surface alternatively along the width of the platform or along the length of the platform.
The adjustable exercise device of 2 wherein the bottom of the platform further defines a plurality of slots disposed about the recess and wherein the inclined riser block further includes a plurality of dimples receivable by the slots to matingly engage the platform and the inclined riser block.
The adjustable exercise device of 8 wherein the bottom of the platform further defines a plurality of slots disposed about the recess and wherein the inclined riser block further includes a plurality of dimples disposed about the flange, some of the dimples receivable by the slots to matingly engage the inclined riser block with the platform at the first position of the inclined riser block and some of the dimples receivable by the slots to matingly engage the inclined riser block with the platform at the second position of the inclined riser block.
The adjustable exercise device of 16 wherein the bottom face of each inclined riser block defines a plurality of slots disposed about the aperture and wherein each riser block further includes a plurality of dimples receivable by the slots to matingly engage each riser block with the respective inclined riser block.
An adjustable aerobic exercise device comprising:
- a platform having a substantially flat top surface, a width, a length and a bottom adapted to rest on a support surface so that the platform and support surface are substantially parallel;
- an inclined riser block with at least one interlocking surface matingly engageable with the bottom of the platform for elevating the platform above the support surface and inclining the platform relative to the support surface,
- the inclined riser block having a height, a first side, a second side, a top face extending at an incline from the first side to the second side, the height increasing from the first side to the second side forming the incline, and a bottom face, the top face of the inclined riser block matingly engageable with the bottom of the platform, the incline of the top face being substantially the same as the incline of the platform when the top face is matingly engaged with the platform, and
- wherein when the platform is stably supported by at least one riser block it is configured to be used for performing aerobic stepping exercise, and
- wherein the inclined riser block is configured to incline the platform relative to the support surface alternatively along the width of the platform or along the length of the platform.
