An exercise apparatus allowing freedom of movement of an exercise bar is provided. The exercise apparatus comprises one or more base assemblies; a pair of spaced vertical members mounted to the one or more base assemblies; and a first bar member mounted to the spaced vertical members, wherein the first bar member is at least partially rotatable relative to the longitudinal axes of the vertical members. The one or more base assemblies may facilitate multidirectional horizontal movement of the vertical members, whereby the first bar member is rotatable relative to the longitudinal axes of the vertical members.

A load-adjusting device for adjusting a load movably mounted to a frame of an exercise apparatus is provided. The device comprises a counterbalance; and a controller, wherein the counterbalance is configured to connect with the load in response to operation of the controller. Operation of the controller may configure the load-adjusting device between an unassisted configuration wherein the counterbalance is not in operative connection with the load, and an assisted configuration wherein the counterbalance is operatively connected with the load. A locking device for selectively constraining a movable component of an exercise apparatus is also provided. The locking device is suitable for use with the load-adjusting device.

A cable exercise device includes a vertically movable weight stack, a rotatable spool assembly, first and second cables, and a movable exercise implement. The rotatable spool assembly is located proximate the weight stack, and comprises spaced apart large and small cable spools affixed to a common rotatable spool shaft. The first cable has a terminal end attached to the weight stack and a winding end attached to the small cable spool. The second cable has a winding end attached to the large cable spool, and extends from the large cable spool to a terminal end. The movable exercise implement is secured to the cable exercise device by the terminal end of the second cable, and is adapted for being employed by a user performing an exercise.

In an exercise apparatus incorporating a vibration pulley system, a vibration unit connected to the frame of the exercise apparatus. The vibration unit may include a toothed pulley and a contact roller mounted on a bracket. A pulley cable may include an end fixedly secured to the frame of the exercise apparatus. The pulley cable may be threaded about the toothed pulley and the opposite end of the pulley cable connected to a handle that may be grasped by an operator. The toothed pulley may be in engagement with the contact roller to generate vibrations that may be felt by the operator. The vibration intensity may be adjusted to variable levels.

An apparatus for physical exercise comprising a resistance arrangement having at least one hydraulic cylinder adapted for providing resistance forces in at least a first and a second direction, the apparatus having a force transmission assembly through which the resistance forces are operable. The force transmission assembly having at least one actuation member being in operable engagement therewith and being adapted to transfer forces generated by a user in at least two directions of motion to the at least one hydraulic cylinder via the force transmission assembly. The resistance forces created by the at least one hydraulic cylinder opposing the user generated forces.

A weight arm assembly for use with a weight lifting rack is provided, the weight arm assembly including a mounting bracket configured to be attached to a vertical surface in a fixed position, an arm mount configured to be coupled to the mounting bracket so as to be pivotable about a first axis, a stop member coupled to the arm mount and configured to move between an engaged position to prevent pivoting of the arm mount through interaction with the mounting bracket, and a disengaged position to allow pivoting of the arm mount, and a weight arm configured to be coupled to the arm mount, proximate a first end of the weight arm, so as to be pivotable about a second axis substantially orthogonal to the first axis.

A spacer apparatus for maximizing a user's range of motion on a weightlifting exercise machine. The spacer apparatus includes a first interlocking part having a semi-circular body extending between top and bottom portions, and a lock portion extending between first and second ends of the semi-circular body. The first and second ends are spaced and a keyway is between the first and second ends. The spacer apparatus includes a second interlocking part having a body extending, at least partially, between first and second ends, and entirely between top and bottom portions. The body of the second interlocking part has a semi-circular portion with a key portion extending therefrom. In the interlocked configuration, the key portion extends between the keyway such that an outer perimeter of the first interlocking part and an outer perimeter of the second interlocking part are aligned.

An exercise apparatus is provided for use with a hip belt or short bar for respectively conducting squat or dead lift exercises, comprising at least one elevated platform secured to a rack, a weight holder, and a guide rod and/or other guide. The weight holder may be designed to hold free weights and to attach onto a hip belt or short bar. As the user performs the desired exercise supported by the platform, the guide rod and/or other guide; guides the weight holder as it is lowered into the hole, limiting movement of the weight holder in the horizontal direction.

An exercise machine may include a support frame with a first and second column; a plurality of guide members movably mounted along both columns; and at least one attachment detachably mounted onto the either column, thereby securing the at least one attachment to the support frame. The at least one attachment may include a first portion; a second portion extending from the first portion; and a locking mechanism extending from the second portion. The locking mechanism may include at least one stationary locking pin received by either column; and a movable locking pin configured to be received by either column. The at least one attachment is detachably mounted onto the either column simultaneously with the plurality of guide members, and at least one of the plurality of guide members positions an operative portion of a weight arrangement at a location along the support frame.

A resistance component configured for imparting a resistive force to a connected exercise component is provided. The device includes a frame pivotally supporting a selection arm which has a weight operatively connected to the selection arm by a pin arm. The weight imparts a force resisting rotation of the selection arm by a flexible member engaged with the exercise component. Adjusting the engagement of one end of the pin arm to an arched engagement path along the selection arm adjusts mechanical advantage and the resistive force.
