Muscle resistance apparatus comprising a framework, at least one resistive force and a movable section. The movable section is linked to a resistive force, wherein a first part of the movable section is attached to the framework by a connection whereby it can be temporarily displaced, and a second part of the movable section is connected to the first part of the movable section by a second connection whereby it can be temporarily displaced. The first and second parts of the movable section are independently movable with respect to one another in an angular and/or linear fashion.

A training sled configurable for adding weights in some embodiments to increase friction and provide for weight-training by lifting portions of the sled. Sled components are slidably or pivotably connected to permit lifting a shoulder member of the sled to different heights and to achieve an optimal training angle.

An apparatus for performing abdominal exercises, the apparatus comprising a frame (10) for providing a stable base for operation of the apparatus, a seat (14) for a user to rest onto, a resistance adjustment means (20) for adjusting level of resistance for operation of the apparatus and a joint mechanism (22) for bearing loads and providing rotational movement, wherein the resistance adjustment means (20) is operable to resist movement of the joint mechanism (22) located at centre point of the frame (10), characterized in that an arm (16) connected to the joint mechanism (22) located at centre point of the frame (10) is rotatable at centre point of the frame (10) by means of the joint mechanism (22) and the seat (14) is linearly connected to the arm (16) and is linearly traversable about the arm (16) and the seat (14) is further rotatably connected to the arm (16).

A reversible resistance exercise machine for reversing the direction of applied resistance against a movable platform of an exercising machine. The exercise machine has a frame, a carriage movably positioned upon the frame, and a plurality of biasing members. A plurality of first tension connectors are accessible near the first end of the carriage and are adapted for removably attaching selected biasing members near the first end of the carriage to resist motion of the carriage in the first direction. A plurality of second tension connectors are accessible near the second end of the carriage and are adapted for removably attaching selected biasing members near the second end of the carriage to resist motion of the carriage in the second direction. A user selectable amount of force may be applied to the carriage to resist movement in either of the first direction and the second direction.

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.

In various exemplary scenarios, some embodiments of the present invention provide a collapsible, user-friendly weighted hip thrust exercise apparatus. Various embodiments of the present invention may consist of a base frame enclosing an exercise space, with an upper body support attached to one end of the frame. The frame may be adjustable in length and/or width in order to accommodate different users. The upper body support may be configured to provide an elevated back rest for the user. In an illustrative example, the upper body support height may be adjustable to accommodate different users. In an exemplary scenario illustrative of various embodiments' usage, a user may sit down in the exercise space enclosed by the frame with the user's upper-back and arms resting on top of the upper body support, placing his or her feet on top of the frame on the other width side. The apparatus may further feature a central resistance band positioned at the user's hip line, coupled to side handles or multiple attachment points, and detent pins to removably lock the apparatus in place for use.

A weightlifting machine includes a carriage support, a carriage moveably mounted on the carriage support and configured to move along the carriage support, and a locking mechanism that is moveable between a locking position, where the locking mechanism engages the carriage and supports the carriage at an elevated position above a lowermost position of the carriage, and a release position, where the locking mechanism does not engage the carriage, and the carriage is free to move below the elevated position.

An exercise apparatus for performing a back extension exercise comprising: a frame, a seat having a seating surface and a pelvic stabilization pad having a lower back engagement surface, an input arm assembly interconnected by a first interconnection to a first resistance mechanism, the input arm assembly including a manually graspable mechanism and being arranged on the apparatus such that the input arm assembly is pivotable beginning from a start motionless position along a path of travel toward the pelvic stabilization pad under resistance exerted by one or both of the resistance mechanisms, wherein the first resistance mechanism is adapted to increase resistance as the degree of pivoting of the input arm assembly increases along the path of travel away from the start motionless position rearwardly toward the pelvic stabilization pad.

A rope fastener includes an insert inserted into a hollow in an end portion of a rope in an elastic tubular form to expand an outer diameter of the rope, a fixing part that is disposed behind the insert and that includes a boss protruding from a front surface thereof and having an insert recess into which an end of the rope is inserted, and a coupling part having a hollow into which the rope is inserted together with the insert and a rear end portion coupled to the boss of the fixing part.

An inflatable plyometric box having a first inflatable member adapted to be inflated to a pressure, a second inflatable member on top of the first inflatable member and adapted to be inflated to a pressure, and a connecting member connected to the first inflatable member and the second inflatable member which secures the first inflatable member to the second inflatable member. The first and second inflatable members incorporate drop stitch technology which provides substantial rigidity to first and second inflatable members when the first and second inflatable members are inflated to the pressures. Thus the inflatable plyometric box is substantially rigid to support a user landing on the top of the inflatable plyometric box. The inflatable plyometric box may include a stabilizing member which may be connected to the bottom of the inflatable plyometric box, wherein the stabilizing member is adapted to increase the stability of the inflatable plyometric box.
