A workout bench and neck exercise system is disclosed. The workout bench may be used in conjunction with a cable weight system and/or cables attached to a head harness or chest harness. The workout bench may include an adjustable handle post and an adjustable stabilization post each of which can be independently adjusted relative to the other with a pin securing mechanism, for example. The workout bench may further include a modular attachment portion configured to be attached to and detached from a corresponding workout component assembly.

A free-weight lifting and support system used by a weightlifter. The system includes a left side support and a left free-weight holder. It also includes a right side support and a right free-weight holder. It further includes a lifting bar, the lifting bar located between the left and right side supports and separating the left and right side supports from each other, and the lifting bar is vertically adjustable relative to the left and right side supports at the same time. The left side support is connected with the right side support via at least the lifting bar such that the lifting bar, the left side support and the right side support are together simultaneously liftable from a ground position to a lifted position by the weightlifter and safely back to the ground position by the weightlifter.

An exercise apparatus comprising: a frame; first and second vertical guides coupled to the frame; first and second carriages carried on the respective first and second vertical guides, each of the first and second carriages having an upper carriage portion, a lower carriage portion and a carriage locking mechanism operable to lock and release the lower carriage portion to a selected vertical position along the first and second vertical guides; and an exercise bar coupled to the upper carriage portion of the first and second carriages, the exercise bar operable to translate or rotate to actuate the carriage locking mechanism.

An adjustable carriage assembly includes a carriage defining a passage configured to receive a frame member therethrough such that the carriage is moveable along the frame member, and a locking structure configured for engaging the frame member to lock the carriage in position relative to the frame member. The locking structure includes a main pin and an auxiliary pin connected to the carriage that are each moveable between a locked position, where the respective pin extends into the passage and is configured to engage the frame member to lock the carriage in position, and an unlocked position, where the respective pin is retracted from the passage and is configured to disengage from the frame member. The carriage may also include a first portion and a second portion, where a space is defined between the first and second portions, and the second portion is adjustable with respect to the first portion.

A bi-directional exercise machine has a work arm, first and second cams coupled to the work arm, a resistance mechanism, and a pulley assembly that couples the resistance mechanism to the work arm via the first and second cams so that movement of the work arm is resisted by the resistance mechanism according to first and second resistance profiles provided by the first and second cams, respectfully. A primary pulley cable has a first end coupled to the first cam and a second end coupled to the second cam. When the work arm is in a rest position, the ends of the primary pulley cable extend from cable tracks of the cams, respectively, at a tangent so that the resistance mechanism applies a resistance force on the work arm via the pulley assembly immediately upon movement of the work arm out of the rest position.

An integrated fitness system including a slidable unit that is slidably attached to a column vertical to the ground and that has exercise units mounted thereon. The exercise units are disposable in any of a plurality of configurations and have arms that are rotatable in any of a plurality of planes. The exercise units can be positioned along the column at any of a plurality of heights by sliding the slidable unit along the column to allow a user to use the exercise units for both arm and leg exercises.

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 machine comprises an arm support, including: a carriage configured to slide within a track attached to the exercise machine; and a support assembly that floats the carriage relative to the track, wherein the support assembly is disengaged by the application of force via the arm. An exercise machine comprises a rotatable column, wherein the column supports an arm, and a gear detent mechanism to support a discrete number of positions for the rotatable column. An exercise machine comprises a tiltable arm, and a mechanism to support a discrete number of positions for the tiltable arm.

A weight stack isolator comprises an impact damper having a rail void therein configured to receive a guide rail of a selectorized machine. The impact damper is shaped to at least partially surround a section of the guide rail when received in the rail void, to secure the weight stack isolator to the selectorized machine. The weight stack isolator may include a slit extending from its outer perimeter to the rail void or the rail void may extend to the outer perimeter, to removably receive the guide rail in the rail void. The weight stack isolator can be positioned under a weight stack of the selectorized machine to absorb or dampen noise and vibration.

A bi-directional exercise machine has a work arm, first and second cams coupled to the work arm, a resistance mechanism, and a pulley assembly that couples the resistance mechanism to the work arm via the first and second cams so that movement of the work arm is resisted by the resistance mechanism according to first and second resistance profiles provided by the first and second cams, respectfully. A primary pulley cable has a first end coupled to the first cam and a second end coupled to the second cam. When the work arm is in a rest position, the ends of the primary pulley cable extend from cable tracks of the cams, respectively, at a tangent so that the resistance mechanism applies a resistance force on the work arm via the pulley assembly immediately upon movement of the work arm out of the rest position.
