An exercise system includes a frame, an upper body carriage, a lower body carriage, a positioning carriage, a resistance assembly attached to the frame, and a connecting mechanism. The frame includes a right guide rail, a left guide rail, and a central guide rail disposed between the right guide rail and the left guide rail. The upper body carriage includes an upper right and an upper left carriage slidingly attached to the right and left guide rail, respectively. The lower body carriage includes a lower right and lower left carriage slidingly attached to the right and left guide rail, respectively. The connecting mechanism mechanically couples one of the upper body carriage, the lower body carriage, or the positioning carriage to the resistance assembly such that the resistance assembly applies a predetermined level of resistive force to the upper body carriage, the lower body carriage, and/or the positioning carriage.

An exercise apparatus for a person to exercise on a support surface includes two side frames that each include a base member, and a front member and a rear member each pivotally attached to the base member. Each side frame is aligned and mutually fixed together at a rear support member joining the rear members and at a front support member joining the front members. Two barbell support members each have a hook at an upper end thereof for supporting a barbell, and are fixed upright on the base members. The exercise apparatus can be configured into a collapsed configuration, circular weights of the barbell acting as wheels while the person grasps and lifts the front sides of the base members. As such the person is able to wheel the exercise apparatus along the support surface. The exercise apparatus may then be reconfigured into an expanded configuration for use.

The invention refers to the equipment of the training rink for floorball, manufacturing of exerciser structural element, applying concept of tennis racket stringing. Proposed design of subsidiary element for floorball rink arrangement characterised with that it is made as latticework formed by: two parallel end plates; several threaded rods as stiffening members; two elastic string structures disposed in two parallel planes, at that each of it presents one side of mentioned latticework and provided with: —holes for fastening threaded rods which assure rigidity and load bearing capacity of the subsidiary element frame structure; —holes for criss-cross stringing in two parallel planes and string fastening at mentioned end plates independently one from another.

A rowing exercise device comprises a support structure; a movable user support movably associated with the support structure for movement relative to the support structure; a movable foot support movably associated with the support structure for movement relative to the support structure; a handle; and a rowing assembly operatively associated with the handle and at least the movable foot support to cause at least the movable foot support to move relative to the support structure with movement of the handle so that both a user s body and one or both feet move relative to the support structure with movement of the handle.

A leg stretching apparatus can be safely used without a risk of damage, with a simple coupling and can be conveniently installed at a site at which leg stretching is desired to enable efficient leg stretching. The leg stretching apparatus includes a fixing plate in which a first fixing plate, which includes a plurality of coupling grooves, and a second fixing plate, which includes a plurality of coupling protrusions corresponding to the coupling grooves, are detachably configured. A fixing part has one end coupled to the first fixing plate and another end equipped with an adjusting part. An elastic string has one end fixed to the fixing part and another end extending in a longitudinal direction of the fixing part, and opposingly branched with two free end portions behind the first fixing plate. A moving part is installed at the second fixing plate to guide the branching of the elastic string.

The invention relates to an alignment aid (10) for golfers which provides a reference means for ensuring optimal positioning of the feet, relative both to each other and a golf ball, for a given club selection. The alignment aid comprises a foot-positioning rail (12); a ball-positioning rail (14); and linking arms (16a, 16b, 18a, 18b). The linking arms are pivotably coupled to the respective rails (12, 14) so as to interconnect them and maintain them in a selected spaced apart, substantially parallel alignment. The alignment aid is adjustable between: (i) a fully expanded condition (FIG. 1) in which the spacing of the respective rails is maximised; (ii) a partially collapsed condition (FIG. 2) in which the spacing of the respective rails is reduced relative to the fully expanded condition; and (iii) a fully collapsed condition (FIG. 3) in which the respective rails and linking arms are arranged in a fully overlapped configuration for storage and/or transport.

An exercise apparatus for targeting the hip muscles is disclosed. The apparatus consists of a plurality of supports, a footboard, and a belt wherein elastic bands may be attached to the belt and to the base supports to provide resistance. The apparatus is fully adjustable for targeting muscles of interest, and collapsible for ready transport. Adjustable handles are optionally provided to maintain user stability and thus maximize the effectiveness of the exercise. A method of using the exercise equipment is also provided.

An isokinetic oscillation exercise device of an elongated flexible blade having a first and second end and a grip portion coupled to a middle portion of the elongated flexible blade. End caps coupled to said first and second ends adapted to storage. Further, a method is disclosed of manufacturing an isokinetic oscillation exercise device that provides a flexible elongated flexible blade, a grip portion injection molding, a pliable ring injection moldings, and end caps injection molding; slides the pliable rings on the elongated flexible blade separated by a length of the grip portion, overmolds a first-shot of the grip portion over the pliable rings, overmolds a second-shot of the grip portion to the first-shot of the grip portion to the elongated flexible blade, seals the first-shot to the second-shot of the grip portion against the pliable rings; and attaches the end caps to the elongated flexible blade.

A cart assembly that is designed to hold and transport one or more ball hoppers. The ball hoppers have baskets that are supported by legs. The baskets are configured to hold some type of ball, such as a tennis ball or a golf ball. The cart assembly can transport the ball hoppers as they are standing on legs. The cart assembly has a platform that is supported by wheels. The wheels provide the platform with the ability to roll. Receptacles are present on the platform. The receptacles are sized, shaped and positioned to receive the legs of a ball hopper when the ball hopper is placed on the platform. Once a ball hopper is attached to the platform, the ball hopper becomes part of the cart assembly and can roll with the cart assembly from point to point.

An apparatus and methods for air filtration are disclosed. The apparatus includes a body and first and second replaceable filters. The body of the apparatus further contains an air-exchange assembly and a filter receiver attached to the air exchange assembly. The air-exchange assembly contains an exhaust tube with an open end and a closed end, two wings on opposite sides of the exhaust tube, and an intake check valve and an exhaust check valve inside the exhaust tube. The first replaceable filter surrounds the filter receiver; and the second replaceable filter is inside the filter receiver. Several apertures and the check valves are strategically disposed in the exhaust tube to achieve optimal air filtration and avoid contamination of a user's exhaust.
