The spherical dynamic resistance device enables simultaneous strength, core and cardiovascular training. A cavity exists whereby resistance bands are stored. By removing a band and connecting it to the exterior of the device at an attachment point and thereafter attaching the other end of the resistance band to a fixed point a user can engaged device to conduct a full body workout. The cavity can also retain a mass element adding weight thereby customizing the weight of the spherical dynamic resistance device. A serpentine channel associated with the outer portion of the device enables a user to grip the device while engaging hand, arm and core muscles. By gripping the device and through various motions that pull opposite of the resistance band while supporting the spherical dynamic resistance device of various weights, a user is able to attain a full body workout.

Methods and devices for isolating muscle groups during exercise are provided. According to an aspect of the invention, a device includes a first strap that has a first loop shape, a second strap that has a second closed loop shape defining a fixed opening, and a third strap that has a third closed loop shape. A first portion of the first strap is affixed to or integral with the second strap, a second portion of the first strap is arranged to be movable within the fixed opening defined by the second closed loop shape, the second portion of the first strap is affixed to or integral with the third strap, and a first adjustable opening within the first loop shape is configured to be adjusted by changing a relative position of the second portion of the first strap and the fixed opening defined by the second closed loop shape.

A portable ski accessory that converts a portable resistance device into a ski-type exercise machine is presented. The ski accessory contains a hanger chassis, a mounting element, a track, a cord, a handle, and a connection element. The hanger chassis contains a cord input portion and a cord output portion. The cord input portion is positioned terminally opposite to the cord output portion along the hanger chassis. The mounting element is connected adjacent to the hanger chassis. The track is positioned within the hanger chassis. The track traverses from the cord input portion to the cord output portion. The cord traverses through the track. The handle is connected to the cord. The connection element is connected to the cord, opposite to the handle.

A physical stretching apparatus having: an anchor strap, wherein the anchor strap is configured to be operable for attaching the apparatus to any stationary object; an anchor joint, the anchor joint is configured to attach the anchor strap and a rope implement; an elastic looped strap configured to secure the apparatus to various points on a user; an attachment contrivance, wherein the attachment contrivance is configured to be operable for attaching the elastic looped strap to the rope implement; a rope lock that is configured to permit the rope implement to pass in one direction when pulled and restricts the rope implement from passing in an opposite or reverse direction; and a release mechanism that disables this restriction and a sliding restrainer, wherein the sliding restrainer is configured to be operable for adjusting a size of the looped strap.

A resistance training system includes a tackle providing mechanical advantage, and a user performs strength training exercises by pulling or pushing on the running block while resisting motion of the running block by pulling or pushing on the free end of the runner. The running block, fixed block and free end of the system may be secured at various locations of the body.

Compact inertial device for muscle training, consisting of a pulling body (1) and a drive rope (2). The pulling body (1) in turn comprises a rotating main shaft (4), a reel (8) mounted on the main shaft (4), an inertia element (6) linked solidly to one end of the main shaft (4) for accumulation of kinetic energy from the rotation of the main shaft (4), and a planetary gear (5), which in turn comprises a central gear mounted on the main shaft (4), for multiplication of the transmission speed from the main shaft (4) driven by the reel (8) to the inertia element (6). In its preferred embodiment, the spool (8) is a conical spool with a smaller diameter sector to which one end of the rope (2) is solidly attached.

An exercise apparatus for strengthening the hips that includes a belt adapted for being tightly secured around the hip area of a user and a resistance band attached to the belt at a position wherein the resistance band resides proximate the hips. An anchor is provided for attaching a distal end of the resistance band to a support generally at a level with the hips whereby rotating the hips applies resistance to the hips providing strengthening resistance to the hips. A method of using the apparatus is disclosed.

The present disclosure relates to a modular strap-based exercise apparatus, kit, and method of use thereof, and more particularly to an apparatus, kit, and method for modularly connecting components of a strap-based exercise device. In an embodiment, the strap-based exercise apparatus includes one or more infinity loops configured to attach various portions of the exercise apparatus together. The exercise apparatus may be provided as a kit including an elongated member, a grip assembly, and one or more mechanisms for adjusting the length of a strap and connecting straps together.

The apparatus provides an exercise device that is portable, versatile, and enables the user to match the resistance of the device with the normal physiologic length-tension relationship of skeletal muscle. The device adds resistance in the form of cartridges that are stackable to summate resistance and can connect to a variety of attachments for use with arms, legs, or trunk, i.e., handle, bar, loop, etc. Given the device's portability, it can be used freestyle or mounted to various surfaces.
