A jump height measuring device with an arrangement of impact elements that are arranged one above the other at a respective distance in a longitudinal direction and which can be pivoted individually transverse to the longitudinal direction, wherein the number of pivoted impact elements forms a measure for a jump height. Each impact element can be pivoted out of a base position against a return force in at least one pivoting direction, up to a defined end position.

An abdominal exercise assembly includes a bracket that is longitudinally elongated to extend substantially across a door frame. The bracket has a pair of foot recesses each integrated into the bracket to have a respective one of a user's feet positioned in the foot recesses. A plurality of foot pads is each positioned on the bracket and each of the foot pads extends along a respective one of the foot recesses to cushion a respective one of the user's feet when the user's feet are extended into the foot recesses. A pair of clamps is each movably integrated into the bracket. Each of the clamps is movable toward or away from the bracket to engage opposite sides of the door frame for retaining the bracket in the door frame.

A boxing training accessory comprises a hand held punching pad with an image of a human face that has a small boxing bag hanging from a lower part of it, representing a human chin/jaw. The accessory provides a more specific target for a user to practice striking techniques and striking combinations while also providing a more realistic look and feel. The training accessory is useful across a range of combat sports including boxing, kickboxing, muay thai, karate, taekwondo, MMA and others.

The present invention is directed to a universal gym facility, comprising: a pair of vertical supporting pillars (11), each attachable to a flat vertical object; at least one training rod (12) horizontally attachable to the supporting pillars (11); and at least one securing facility (20), for securing the training rod (12) to one of the supporting pillars (11).

An easy-to-disassemble connecting rod with a cam structure includes a connecting rod and cams. Two ends of the connecting rod are hinged with the cams. An outer side surface of each cam includes an arc surface, a radius of curvature of the arc surface of each cam around a shaft hole gradually increases, and rotation directions of the two cams are opposite. The technical effects achieved are as follows: in the easy-to-disassemble connecting rod with a cam structure provided by the connecting rod, two ends of the rod contact with the supporting surface via the cams, the pressure on the wall is increased or decreased via radius change caused by rotation of the cams, and further the friction force is increased or decreased, so as to achieve safe and rapid installation or disassembly.

A multi-functional doorway exercise device is an apparatus that safely and securely attaches to a door frame. The apparatus includes a stabilizing bar, a main pullup bar, a first support bar, a second support bar, a left bracket assembly, a right bracket assembly, a left handlebar, and a right handlebar. The stabilizing bar extends across the width of a door frame and locks into the door frame. The main pullup bar, the left handlebar, and the right handlebar allows a user to grasp onto the present invention while performing various exercises with different grip positions. The left bracket assembly and the right bracket assembly attaches the stabilizing bar onto and along both sides of the door frame. The first support bar and the second support bar connect the main pullup bar with the stabilizing bar and allows the main pullup bar to rotate about the stabilizing bar.

An exercise anchor for elastic bands or other exercise implements that mounts to a standard door hinge. The exercise anchor allows for an easy, secure, and unobtrusive mounting to a door hinge through the hinge pin, or with a hinge pin integrated into the exercise anchor. It may also be provided as a kit with a variety of specialized hinge pins to provide extra support or to adapt a single exercise anchor to hinges that require hinge pins of differing shaft diameters or differing lengths. The exercise anchor may be mounted without the need to modify or drill into walls or fixtures, and may include features for added security and to prevent inadvertent pull-out of the anchor, such as anchor braces, bump stops, and hinge captures. The exercise anchor may also include a variety of band capture shapes, geometries, or arrangements allowing use versatility when engaging in various exercises.

A foldable exercise device with a chin-up exercise apparatus and a dip exercise apparatus suspendable from the chin-up exercise apparatus. The chin-up exercise apparatus has a top horizontal member and a bottom horizontal member connected by two connecting members. Each connecting member has a door header hook and a parallel chin-up handle that rotate on the connecting member from a flat configuration to an exercise configuration. In the exercise configuration the chin-up exercise apparatus can engage a door frame. In the exercise configuration the parallel chin-up handles can be used for neutral chin-ups. The dip exercise apparatus has two vertical members spaced apart by a horizontal connecting member. The vertical members have a bottom end with a bottom grip. The bottom grip can be rotated from a flat configuration to an exercise configuration. In the exercise configuration the bottom grips can be used to do dip exercises.

The present invention relates to an exercise bar mounted on a door frame, and to an exercise bar mounted on a door frame capable of preventing a user's face or head from hitting an edge part of an upper end of the door frame when a user bends her or his arms to pull her or his upper body upward and hang her or his chin on a horizontal rod during an exercise such as a chin-up, and in which a height of a pipe member installed at the door frame can be adjusted according to a height of the user.

The present invention relates to an exercise machine that has all the functionality of a standing, bulky, multifunctional exercise machine, but can be mounted on a door frame so that it can quickly and conveniently change from full exercise functionality to full doorway functionality without any removal or disassembly of any components.
