In some embodiments, a battle rope strength trainer device is provided. The battle rope strength trainer device provides a multifunction exercise device that combines strength building properties of body weight strength exercises with the cardiovascular training of battle rope oscillation exercises in one product. In one embodiment, the battle rope strength trainer device includes an anchor, a rope and a mounting device. The rope includes a first end coupled to the anchor and two free ends. The first end is attachable to a structure via the anchor and the two free ends are positioned opposite to the first end. The mounting device is coupled to the structure above the anchor. In that regard, the mounting device is adapted to receive a portion of the rope associated with each of the two free ends to enable movement of the rope for a plurality of exercises.

Embodiments of the present invention provide an adjustable strap apparatus and methods of instructing a patient to perform an exercise using the adjustable strap apparatus. An apparatus according to embodiments of the present invention includes a strap, a plurality of hook patches and a plurality of loop patches joined thereto. A hook patch and a loop patch of the present invention are removably engageable to form pull loops from ends of the apparatus and to form a pull belt between the pull loops. A therapist may instruct a patient to perform a mobilization exercise or a stretching exercise by forming pull loops about extremities of the patient and pulling on the apparatus without grasping to exert a stabilization force or resistance force upon a part of the body of the patient.

In various embodiments, an apparatus for exercising can include a housing, a first inner tube, a second inner tube, and a compression spring operable to resist motion when compressed. The first inner tube is coupled with a first end of the compression spring and the second inner tube is coupled with a second end of the compression spring. In addition, the apparatus can also include an extension spring inside the housing. Furthermore, a portion of the compression spring and a portion of each of the first and second inner tubes are inside the housing. Note that a first end of the extension spring is coupled with a first handle or loop and the second end of the extension spring is coupled with a second handle or loop. The extension spring is operable to provide resistance during pulling motion away from center of the apparatus.

A fitness device contains a strap, a handle, and a plate. The strap is substantially inelastic and flexible. The plate is substantially rigid. The handle at least partially envelopes the strap. A method of exercising with such a fitness device is also described herein. Other fitness devices and other methods of use are also described herein.

A multifunctional arm cranking exerciser includes an omnidirectional support bracket assembly, which comprises a five-way bracket mounted to a top thereof and having a left side to which a left arm exercising device is mounted and a right side to which a right arm exercising device is mounted. Also mounted on the five-way bracket are a damping adjustment device and a quick release pin device. The quick release pin device allows for quick coupling and positioning of left and right arm cranks of the left and right arm exercising devices at an angular difference of 0 degree or 180 degrees and also allows for quick release and decoupling of the left and right arm exercising devices to be independent of each other. The damping adjustment device adjusts and regulates a level of damping for achieving an effect of efficient exercising.

A pulley system of an exercise device for suspended weight training includes a first block with a first pulley, a second pulley, and a first attachment point. A second block is removably coupled to a weight and includes a third pulley and a second attachment point. A grip is configured to be held by a user while exercising and has a third attachment point. A line having a first line end is fixedly coupled to the grip and a second line end fixedly is coupled to a connection element. The connection element is configured to be selectively coupled to each of the first attachment point, the second attachment point, and the third attachment point, permits a user to reduce an effective amount of the weight lifted by the user with movement of the grip to a pre-selected fraction of the weight.

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 rebound and balance training device includes a frame, a footboard, and a plurality of resilient spring elements extending between and attached to the frame and the footboard to support the footboard above a supporting surface. A user standing on the footboard manually effects repeated vertical bouncing movement between upper and lower positions. The distance traveled by the footboard, the effort required to effect movement, and the stability thereof may be modified by selectively modifying the number, the length, the position, or the elasticity of the resilient elements. In one embodiment, a pair of footboards is employed to simulate skiing movements.

A method is disclosed for using an artificial intelligence engine to modify resistance of pedals of an exercise device. The method includes generating, by the artificial intelligence engine, a machine learning model trained to receive measurements as input, and outputting, based on the measurements, a control instruction that causes the exercise device to modify, independently from each other, the resistance of the pedals. While a user performs an exercise using the exercise device, the method includes receiving the measurements from sensors associated with the pedals. The method includes determining, based on the measurements, a quantifiable or qualitative modification to the resistance provided by a pedal of the pedals. The resistance provided by another pedal of the pedals is not modified. The method includes transmitting the control instruction to the exercise device to cause the resistance provided by the pedal to be modified.
