Abstract

An exercise device guides the user during performance of a squatting exercise while the exercise device repetitively moves down and up any suitable vertically oriented surface, such as a wall. During performance of the squatting exercise the user rests against a back support surface. Rolling members provide for a smooth rolling contact between the exercise device and the wall during performance of the squatting exercise. A grip member, or members, positioned distal from the rolling members and in front of the user provides the user with ready and true control over the exercise device during the performance of the squatting exercise. The squatting exercise achieved using the exercise device strengthen or otherwise tone many muscle groups including the quadriceps, the knees, the hamstrings, the ankles, the glutenous maximus, the abdomen and the lower back.

Claims

1. An exercise device to support a user at a portion of a back of the user during a performance of a squatting exercise by the user, the performance of the squatting exercise by the user occurring while the back of the user is displaced vertically adjacent to a planar vertically oriented surface, the exercise device comprising:

a) a plurality of rolling members having a bearing plane, the rolling members to contact the planar vertically oriented surface during the performance of the squatting exercise generally at the bearing plane of the rolling members, the rolling members to provide for a smooth rolling contact of the exercise device with the planar vertically oriented surface during the performance of the squatting exercise;

b) a back support surface to contact the portion of the back of the user during the performance of the squatting exercise, the back support surface positioned on the exercise device relative to the rolling members, the back support surface having an average spacing distance from the bearing plane of the rolling members;

c) a grip member for grasping by the user during the squatting exercise, the grip member positioned on the exercise device relative to the back support surface, the grip member having an average spacing distance from the bearing plane of the rolling members and wherein the average spacing distance of the grip member from the bearing plane of the rolling members is significantly greater than the average spacing distance of the back support surface from the bearing plane of the rolling members;

d) mechanical resistance means to provide for a mechanical increase in a resistance to movement from a first operational position relative to the planar vertically orientated surface to a second operational position relative to the planar vertically oriented surface during a winding of a mechanical member and a mechanical decrease in a resistance to movement from the second operational position relative to the planar vertically oriented surface to the first operational position relative to the planar vertically oriented surface during an unwinding of the mechanical member; and

wherein the mechanical member of the mechanical resistance means further comprises a coil spring member.

2. The exercise device defined in claim 1 wherein the coil spring member further comprises a round cross section.

3. The exercise device defined in claim 1 wherein the mechanical increase in the resistance from the first operational position to the second operational position occurs during movement from an elevated position relative to the planar vertically oriented surface to a lowered position relative to the planar vertically oriented surface during the performance of the squatting exercise.

4. The exercise device defined in claim 1 wherein the mechanical resistance means further comprises a significant mechanical resistance commencing from initial movement from the first operational position relative to the planar vertically oriented surface during the performance of the squatting exercise.
