A resistance device capable linearly adjusting training load comprising: a rack unit with two vertical rods, and two sliding units, which are connected to a handle and a pedal; a linkage unit with a chain and a belt, and are locked on the connecting plate; and two damping units make multiple magnet pieces arranged on both sides of a fixing base, and a diamagnetic metal piece is arranged on the connecting plate, and set trough the fixing base to cut the magnetic circuit generated by the magnet pieces to form damping: When the user steps on the pedal, the connecting plate will drive the metal sheet to cut the magnetic circuit, and the damping can be changed to further achieve the effect of linearly adjusting the training load.

A portable, wearable resistance band training apparatus having at least one resistance device secured in a channel of a strap portion forming shoulder straps, and a plurality of access openings in the shoulder strap portion for grasping and extending the resistance device from the sleeve for performing one or more resistance training exercises.

Interactive/smart resistance band training systems include one or more resistance bands connected to a force sensing unit that registers the force exerted by a user on handles connected to the bands. The sensing unit operates effectively regardless of whether the user is training with one handle individually, or with two handles being pulled in parallel or non-parallel directions. The systems may correct the force readings to account for non-alignment between the force-measurement axis of the force sensing unit and the directions in which the user applies force to the resistance bands. The systems may guide a user through exercise sessions tailored to the fitness level of the user; may display the force readings, calories burned, and other performance parameters and goals on a continuous, real-time basis; may summarize the result of the exercise session; and may recommend subsequent exercise sessions based on the performance of the user.

An apparatus and method to evaluate the endurance of a muscle group of a user by measuring velocities of an engagement assembly coupled to a resistance element and moved by the user through a plurality of exercise strokes. A muscle group is assessed by determining a rate of fatigue for the muscle group. The method can include adjusting the controllable resistance to a resistance level, monitoring the movement of the engagement assembly against the resistance level over a plurality of repetitions, determining a relationship between the movement of the engagement assembly by the user over the plurality of repetitions, and using the relationship to determine the rate of fatigue.

Methods and systems are presented in which one or more heavy-duty straps are positioned in contact with a top and bottom of a door and engaged with a heavy mechanism exerting a static tension greater than 10 newtons. A user can exercise using removable extenders attached to any of several loops at various vertical positions, creating enormous leverage along the strap(s). Supplemental cushioning may be utilized to minimize damage from large kinetic energy imbued upon components of the methods and systems during or after exercise.

An exercise machine has a two-part hexagonal base. A plurality of supports is attached to the two-part hexagonal base, and a pair of intermediary elastics, each arranged by crossing one side extremity of the two-part hexagonal base from a top extremity of the exercise machine to the bottom face of the opposite extremity of the two-part hexagonal base. A top two-part bar is arranged horizontally between tops of the pair of intermediary elastics. A top cylindrical wheel arranged and centered on the top two-part bar, wherein the two-part hexagonal base having a set of cylindrical openings spaced along an entire length of the two-part hexagonal base, two side openings, two rollers, arranged transversally centered in a one of the two side openings, a bottom hollow arranged along the an entire length of the bottom of the two-part hexagonal base, two pairs of straight bottom bars arranged centered and spaced on and along the entire length of the bottom face of the two-part hexagonal base.

The present invention discloses a swing exercise machine including a support frame, a pair of footrests disposed at both sides of support frame and at least one suspension arm disposed between footrests and support frame, each footrest is rotatably connected to at least one suspension arm, and a pivot assembly is provided between the support frame and each suspension arm. The present invention is equipped with a support frame, a pair of footrests, and at least one suspension arm disposed between each footrest and support frame, each footrest is rotatably connected to at least one suspension arm, the connected X and Y pivot assemblies are disposed between suspension arms and support frame to allow footrests to swing back-and-forth, left-and-right. The present invention has simple structure and small volume, can realize effect of large-scale forward, backward, left and right movement of footrests through suspension arms, thus can effectively realize fitness effects.

A connector for a resistance band for strength training includes: a first connector configured for attachment to an end portion of an elastic, elongate first cable of the resistance band; and a second connector configured for attachment to an end portion of an elastic, elongate second cable of the resistance band and configured to detachably couple to the first connector. Each of the first and second connectors includes a pair of male mating features, and a pair of female mating features configured for removable receipt of the respective pair of male mating features.

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.

A preloaded resistance pack and exercise device. The resistance pack includes an elastomeric resistance element coupled to a hub and disposed on a plate. The hub includes a pair of radially extending wings that lie against a surface of the plate. The plate includes a pair of raised tabs that lie within a rotational path of the wings. An initial rotation of the hub relative to the plate causes the wings to slide over and beyond the raised tabs and at least partially stretches the resistance element. Interaction between the tabs and wings prevents the hub from rotating back to an initial position and maintains the resistance element in a preloaded, tensioned condition. The exercise device is configured to detect a number of the resistance packs coupled thereto as well as data associated with exercise movements employing the resistance packs.
