The invention is embodied in an exercise system that can allow its user to counterbalance the effects associated with a predominantly sedentary lifestyle though a fitness device that comprises a combination of (a) supporting the lower body in a manner that permits a user's upper body to act as a third class lever with the user's hips operating as fulcrum and (b) engaging in resistance exercises with the upper body in a horizontal position, unsupported above the greater trochanter.

An exercise system is provided for enabling a user to perform therewith a modified plank exercise, the exercise system includes: a top element having an interface for the user to hold or rest thereon; and a bottom element having an interface with a ground surface, the top and bottom elements interconnected and separated from each other with a middle element. At least one of the top and bottom elements is interchangeably coupled to the middle element, and the exercise system includes at least one element of instability that is overcome by involving core muscles of the user.

A device that is used to extend the spine and put it in traction, that is portable and user friendly. The device in an embodiment is grasped by the handles on either side and then is pushed toward the lower leg and against the upper calves via vertical intermediary bar pushing the legs with a horizontal bar in one direction and the shoulders in the other. The described process stretching the spine and putting the back in traction for the purposes of pain relief and stretching of the back muscles. The device can be an inexpensive alternative to other devices, as well as, easier to use. The force placed on the device and therefore on the spine or back is controlled by the user as is the ability to stop quite quickly if pain were to arise, giving the user complete and instant control.

A portable and removable mounted exercise station includes an elongated anchoring member disposed on a surface of an external stationary object, such as a wall. The anchoring module has a doorknob shaped cleat, a plurality of knobs, and brackets formed in both ends of the elongated anchoring member. A corner mounting adapter to mount the station in a corner where two walls meet. A resistance band connects to one of the knobs to provide resistance during an exercise routine. A clip allows for quick connect and disconnect of the resistance band to the station.

The exercise machine in the present disclosure utilizes novel machine mechanics that accommodate and adjust to the spines shifting axis of rotation. Through the use of a multiple, articulating axes a back exercise machine or device that promotes pure and isolated spinal flexion and extension with no need for mechanical anatomical restraint to succeed has been created. Using these mechanics when users attempt to extend their trunk, the device adjusts to the natural shifting axis of rotation of the spine thereby dis-involving the contribution of the hip extensor muscles. In other works, the exercise back machine of the present disclosure is designed to accommodate the complex biomechanics of the spine and to facilitate targeted strengthening of the spinal erectors and deep intrinsic spinal muscles.

A cervical spine and muscle strengthening apparatus is provided having a faceplate configured with an opening, a plurality of fastening devices, coupling devices and a resistance source. The plurality of fastening devices may be attached to the faceplate to provide an attachment point at one end of each coupling device. The plurality of coupling devices extends away from the faceplate and attach to the resistance source at the second end of each coupling device. The faceplate may be fabricated from wood, composite, plastic, metal, metal alloy or other suitable material. Additionally, the plurality of fastening devices and coupling devices may be fabricated from metal, metal alloy, composite, plastic, or other such material

A lower back exercise apparatus exercises or imparts laterally and upwardly directed movements into a user's lower back when seated thereupon. The lower back exercise apparatus includes a lower base assembly, an upper seat assembly, and a motor assembly. The lower base assembly includes an upper, laterally concave base surface. The upper seat assembly includes a lower, laterally convex seat surface and an upper seat surface. The upper seat assembly is laterally ridable upon and movable relative to the lower base assembly. The motor assembly is drives a laterally directed, cylindrical arc length trajectory of the upper seat assembly relative to the lower base assembly. The concave and convex surfacing have a common radius of curvature with a common fulcrum point spatially located adjacent an upper portion of a user's lumbar spinal region. Lateral flexion is thus imparted into a user's lower back when a user is seated thereupon.

An exercise apparatus with an adjustable rotating element around which a force transferring material wraps either clockwise or counterclockwise to provide bidirectional rotational resistance for exercising. The force transferring material is preferably guided to remain in close proximity to the rotating element while wrapping around the rotating element.

An exercise machine for performing prone leg curl exercises, including a moving support platform or frame that allows a user to perform prone leg curl exercises without excessively arching his or her lower back.

Methods and apparatuses (e.g., devices and systems, including garments and software) for improving rotational symmetry in a subject in need thereof. These methods and apparatuses for asymmetrically weighting the subject may engage with the subject's multifidi muscles and therefore adjust for rotational deficit in the subject.
