The system of the present invention includes elastic bands that are affixed and inserted within elastic band insertion slots that are disposed on a u-shaped frame and a rectangular-shaped frame. The squatting motion the user performs on the present invention activates the expansion and retraction of the elastic bands, which exerts resisting force upon the user, simulating weights.

A door frame attachment system includes a pair of pivotable arms that can hook onto a door trim, held closed by a spring hidden in a cavity between the arms. The arms are connected to each other by a hollow shaft that allows various handles to be hung from the system. An exercise device includes the door frame attachment system and a handle suspended by a rope that passes through the hollow shaft. The device offers greater portability and attachment security compared to other inventions of this class, and it also provides greater user comfort by allowing the handles to rotate and pivot into a natural position.

An exercise device and an inflatable alternative are provided. The exercise device is composed of a planar base attached to block(s). The block(s) may serve as cushioning or weighted items to enable a variety of exercises. The planar base is securable against a structure such as a door frame. The planar base is also convertible to a bench with shaft(s) that connect block(s) to form legs for the bench. The inflatable alternative includes a top end that is securable to the structure. A bottom end of the inflatable alternative is securable to a user through an ankle cuff. The ankle cuff provides the user a measure of control over a mobility of the inflatable alternative during an exercise.

An apparatus for exercising against a resistance comprises a frame comprising a plurality of vertical members mutually supporting a plurality of horizontal members, wherein the frame has at least a front face joining a side face at a corner; one or more doors comprising one or more door vertical members mutually supporting one or more door horizontal members, the door being pivotally and optionally slidably mounted to the frame in at least one point; wherein the frame and optionally the door provide at least one exercise attachment point. A hinge, useful for example in such an apparatus, comprises a frame brace rotatably joined to a door brace by a hinge axle, wherein the frame brace is adapted to slidably engage a track affixed to the frame of the apparatus.

Exercise equipment provides maximum effort repetitions, every rep, safely, through constant velocity. With constant velocity resistance, every person using the equipment can achieve maximum resistance for each repetition, whether their strength maxes out at 5 lbs. or 500 lbs. of resistance. The constant velocity resistance allows for reduced resistance with each repetition as fatigue sets in, without changing the equipment settings. The exercise equipment includes a line coupled to a handle, and retracted by a retraction assembly. An impeder provides resistance for pushing/pulling (depending on the exercise) based on constant rotational velocity of the impeder, rather than resisting with a force of gravity, spring force, or friction. The impeder prevents extraction of the line faster than the constant rotational velocity. Thus, a user can push/pull as hard as desired, and the line can only be extracted as limited by the velocity of the impeder.

Disclosed is an exercise device for mounting in a door frame, including an elongated body having a top surface for attaching to a doorframe, a bottom surface, a left side, and a right side, a T-slot formed length-wise in the bottom surface of the body and opening to the left side and the right side of the body, the T-slot having a first and second undercut portions of the T-slot, a bottom wall of the T-slot connecting the first and second undercut portions, a plurality of holes in the bottom wall of the T-slot and extending to the top surface of the body, an exercise accessory having a connecting member, a cutout in the T-slot on the bottom surface of the body for receiving a head of the connecting member, the cutout sized in relative proportions to allow the head of the connecting member to pass therethrough and the head of the connecting member sized to be received in the T-slot of the body and configured to be slidably retained in the T-slot.

The present invention is a portable rehabilitative training device comprising a board that has a greater length than its width with alternating parallel rungs and grooves formed in the board that run up and down the boards length is its front surface for use with a person's hands and fingers. The rungs have a flat surface on their top edge and a beveled surface on their bottom edge. The board also has at least one slot formed through the board with such slot being formed in the uppermost groove and also formed in various other groups for purpose of height installation. The slots are used in conjunction with a support strap having a permanent stop formed on one end and the other end has a loop end such that a removable stop can be inserted into the strap loop end once it has been inserted through the back of the slot on the finger board such that it advances through the front of the finger board. The finger board is installed on a door by laying the support strap over the top edge of the door and closing the door.

Disclosed is an exercise device having an elongated body, a slot formed length-wise in the body, the slot having an undercut portion on each side, a plurality of holes in slot for receiving one of a plurality of fasteners, an exercise accessory having a connecting member, and a head of the connecting member, the head sized to be received in the slot of the body and configured to be slidably retained in the slot. The slot can have undercut portions. The undercut portions can have locking features. The head of the connecting member can have complimentary locking features. A tightening member can fix the connecting member in a position in the slot. The elongated body can have a cutout for receiving the head of the connecting member.

The present invention provides portable modular hanging and pulling system for temporary mounting in a doorway formed above a floor and along a wall, the wall having a first opposing side and a second opposing side, the doorway includes a door attached to a door frame on the first opposing side with a door hinge, and a supportive strip positioned above the doorway on the second opposing side. The portable modular hanging and pulling system includes: a first bearing member, a second bearing member, a first coupling member, a second coupling member, and a modular surface.

A door frame fitness equipment, comprising two fixed frames set side by side, one end of which is bent upward and fixedly mounted with a fixed hanging plate, which is hung on upper support surface of door frame; a center crossbar, set perpendicularly to two fixed frames, said center crossbar is mounted on upper end or lower end of two fixed frames, and both sides of center crossbar extend outwardly towards two sides of fixed frames; two center connectors, respectively used to connect two fixed frames and center crossbar, two fixed frames and center crossbar pass through two center connectors respectively and are fixedly connected with said center connectors. The disclosure adopts principle of leverage to lock whole fitness equipment on the door frame at both sides, making fixing more solid and stable, and it can be equipped with different accessories to realize expansion of functions.
