Improved designs for exercise machines that facilitate muscle development and other therapeutics are disclosed. The machine includes a frame, a pulley assembly, and cable extending through the pulley assembly. The cable has attachments, including an attachment for connecting to a pull handle. The cable is also connected to a selectively variable moveable resistance unit. This unit is structured to provide an elastic resistance when a pulling force is applied to the pull handle. The unit is connected to the cable and includes an elastomeric body that provides the elastic resistance and also includes an arc plate that provides a curved support member on which a portion of the elastomeric body at least partially wraps around. Movement of the arc plate causes the elastomeric body to stretch and to provide the elastic resistance.

An exercise machine which includes a centralized spring box and multiple gripping surfaces with which an exerciser may perform a wide range of exercise moves. The exercise machine includes a movable carriage and platform on a track. Bias members may be connected between the carriage and various structural elements of the exercise machine so as to impart a resistance force against movement of the carriage. An outer handle may be positioned around a carriage platform so as to surround the carriage platform. Inner handles may be positioned between the carriage platform and the outer handle, with the inner handle(s) being connected not to the outer handle or the carriage platform, but to an underlying support assembly. A pair of end handles may extend outwardly from the ends of the exercise machine. A bias member retainer such as a spring box may be centrally-located along the length of the exercise machine.

The invention relates to an improved device for suspension training, having a central pulley which is secured by a carabiner with a safety closure and through the channel of which slides an 8 mm cord restricted by sliding cord loops into which are hooked flat carabiners that connect same to handles formed by a flat strap and a tube with a cushioned surface, the device also having a strap of loops.

An exercise bar is provided. The exercise bar includes a handle tube with a longitudinal interior bore. The handle tube has a first end and a second end. A center shaft has an outer surface. The center shaft is fitted through the longitudinal interior bore exposing a first end portion of the center shaft at the first end of the handle tube and exposing a second end portion of the center shaft at the second end of the handle tube. A sensor is disposed on a mounting section of the outer surface of the center shaft between the first and second portion of the center shaft. A processor is disposed in an interior of the exercise bar. The sensor is in electronic communication with the processor in the exercise bar.

An exercise apparatus for assisting a user with a range of exercises includes a frame having a first frame section extending in a generally horizontal direction. At least one carriage is configured to support a user, wherein the carriage is slidably supported on the first frame section. A first resistance system has a first resilient member removably connected to at least one of the carriage and/or the frame. The displacement of the carriage relative to the frame exerts a tensile force on the resilient member. A second resistance system includes a load moveably mounted with respect to the frame and an actuation member connected to the load. The actuation member is configured to displace the load when a force exerted by the user on the actuating member exceeds a predetermined threshold representative of the load.

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.

A transformable exercise apparatus is disclosed. The exercise apparatus includes base arms parallel to each other, front legs and rear legs extending from the base arms. The exercise apparatus includes top arms, each connecting respective front and rear leg of each base arm. The exercise apparatus presents telescopic members stored in the front legs. The exercise apparatus includes a first table top and a second table top. The second table top includes collapsible legs. The collapsible legs fold and allow for placing the second table top and the first table top over the top arms, thereby transforming the exercise apparatus into a furniture. The second table top demounts and transforms into a workbench. The telescopic members extend and include a pull-up bar at the top, transforming the exercise apparatus into a pull up exercise apparatus. The apparatus may transfer into a leg press and arm press.

A cable hook for fixing a rebound mat to a trampoline frame by means of two elastic elements and at least one flexible strap element has a housing with four receivers, wherein each elastic element has two free ends, each of which has a clamping element enlarging the periphery of the elastic element. A clamping element is inserted in each receiver. The cable hook has a cable hook body which is closed in the peripheral direction transversely to the fixing direction, wherein in each case two receivers are separated centrally by a receiving cavity in the cable hook body through which a clamping element can be passed. The cable hook has two terminating pieces which can each be inserted in a respective receiving cavity, and each has a cover rounding pointing away from the cable hook housing and oriented towards each other.

Embodiments herein describe an archery training device for improving shooting accuracy. The device has a rigid body graspable by one hand, an elastic section for providing resistance, and a string coupled to the elastic section with a loop on the opposite end. The device further includes an adjustable string length and adjustable resistance to match a particular configuration of a bow for a particular sporting enthusiast or hunter.
