Abstract

A device which restricts movement of the knee during lunge and squatting exercises prevents weight imbalance which may result in undue strain and knee injury. The device has a foot engagement member stepped upon by the user and held in place by the user's weight, or the foot engagement member conforms to the side of the user's foot and is held in place by a strap. Attached to the foot engagement is a vertical member extending upwardly from the foot engagement member. A shin engagement member attached to the vertical member is generally positioned in a position along the lower leg of the user, below the knee and laterally adjacent to the user's tibia. As the user performs exercise, the shin engagement member prevents the user's knees from forward movement which extends forward of the user's feet. The device also has structure which prevents inward collapse of the knees.

Claims2

Dependent claims

A device for assisting a human user in properly performing a leg exercise, the leg exercise of the type where, for a single repetition of the exercise, the user starts in a standing position with his or her feet flat on a ground surface, with the toes of each foot pointing forward, the user thereafter leans forward on a first leg attached to a first foot, and begins to bend at a first knee of the first leg and continuing to bend at the first knee until a portion of the first leg about the first knee is substantially parallel to the ground surface, and completing the repetition by rising back to a standing position, wherein, in the proper performance of the above described repetition, the user's first knee does not extend forward of the toes of the first foot and does not turn inward, the device comprising:

a rigid foot engagement member sized and shaped to engage the first foot the foot engagement member defining an open bottom such that the first foot of the user contacts the ground surface when said device is in use and wherein the foot engagement member is adapted to contact only a top and an inside edge of the user's foot;
a rigid shin engagement member attached to the vertical member, the shin engagement member sized and shaped to abut a portion of the lower front of the first leg, the shin engagement member comprising structure which restricts forward movement;
a rigid round surface support member extending laterally from the foot engagement member and oriented such that the ground surface support member extends parallel to the ground when a wearer of the device is standing on the ground, thereby restricting inward movement of the user's knee;
and
means for retaining the device in engagement with the first leg.

2 more elements

A system for assisting a human user in properly performing a squatting exercise, the squatting exercise of the type where, for a single repetition of the exercise, the user starts in a standing position with his or her feet flat and spread approximately a shoulder width apart with his or her toes pointing forward, the user thereafter pushes his or her hips rearward and begins to bend at the knees, maintaining the lower legs substantially motionless, continuing to bend at the knees until the top of the user's hips have descended below the top of the user's knees, and completing the repetition by rising back to a standing position, wherein, in the proper performance of the above described repetition, the user's knees do not extend forward of the user's toes and do not turn inward, the system comprising:

a pair of rigid foot engagement members each sized and shaped to engage one of the user's feet, the foot engagement members each defining an open bottom such that the feet of the user contacts a ground surface when said device is in use and wherein each foot engagement member is adapted to contact only a top and an inside edge of the user's foot;
a pair of rigid vertical members, each attached to a corresponding foot engagement member, the vertical members each comprising structure which causes each vertical member to remain substantially stationary during the repetition of the squatting exercise;
a pair of rigid shin engagement members each attached to a corresponding vertical member, each shin engagement member sized and shaped to abut a portion of the lower front of one of the user's legs, the shin engagement members comprising structure which restricts forward movement of the user's knees during the repetition of the squatting exercise,
a pair of rigid ground surface support members extending, each extending laterally from a respective foot engagement member, the pair of ground support members oriented to extend parallel to the ground when a user of the system is standing on the ground, thereby restricting inward movement of the user's knee;
and
means for retaining the foot engagement members in engagement with the feet of the user.
