Patent Images
1. A step exercise system for an aerobic step workout, comprising:
- a portable inclined step ramp having a main body portion, said main body portion having an upper workout surface portion;
a plurality of adjustable legs extending from said main body portion, each adjustable leg having a retracted supporting position and an extended supporting position;
each leg including means to lock said adjustable leg in one of said retracted or extended supporting positions;
each adjustable leg including a telescoping portion, a fixed portion and means to resist movement of said telescoping portion relative to said fixed portion, said resistance means being operable to allow a user to articulate said adjustable leg between said retracted and extended supporting positions, and being operable to substantially prevent articulation of said adjustable leg absent a force applied by said user;
said resistance means being independent of said means to lock said adjustable leg in said retracted and extended positions.

Abstract
A step exercising system for an aerobic step workout is constructed as a portable inclined step ramp. The ramp is sloped towards a user such that the user can step up onto the ramp at various heights, thereby regulating the degree of intensity of the workout without having to suspend the workout to adjust the step height, as is the case when using a conventional aerobic step having a raised level platform.

4. A step exercise system for an aerobic step workout, comprising:
-
a portable inclined step ramp having a main body portion; a plurality of adjustable legs extending from said main body portion, each adjustable leg having a retracted supporting position and an extended supporting position; each adjustable leg having a fixed portion fixedly attached to said main body portion and having a telescoping portion which translates relative to said fixed portion; said adjustable leg having a longitudinal axis aligned oblique to a support surface; each adjustable leg having a contact surface aligned oblique to said longitudinal axis of said adjustable leg; each contact surface being substantially planar and comprising a substantial portion of a bottom surface of said adjustable leg; and said contact surfaces of said adjustable legs being substantially parallel to said support surface when said adjustable legs are in either said retracted or extended supporting position. - View Dependent Claims (5, 6, 7, 8, 11)

9. A step exercise system for an aerobic step workout, comprising:
-
a portable inclined step ramp having a main body portion; a plurality of adjustable legs extending from said main body portion, each adjustable leg having a retracted supporting position and an extended supporting position; each adjustable leg having a fixed portion fixedly attached to said main body portion and having a telescoping portion which translates relative to said fixed portion; said adjustable leg having a longitudinal axis aligned oblique to a support surface; each adjustable leg having a contact surface aligned oblique to said longitudinal axis of said adjustable leg; said contact surface of said adjustable legs being substantially parallel to said support surface when said adjustable legs are in either said retracted or extended supporting position; said contacting surfaces of said adjustable legs being substantially co-planar when said adjustable legs are simultaneously in either said retracted or extended supporting position; said main body portion including an underside portion and wherein said longitudinal axis of each adjustable leg is substantially perpendicular to said underside portion; said telescoping portion rotating about said longitudinal axis of said adjustable leg relative to said fixed portion, and said telescoping portion is in a same rotational orientation relative to said fixed portion when said adjustable leg is in either said retracted or extended supporting position.
