An isometric exercise apparatus adaptable to an existing treadmill or similarly shaped platform provides a height-adjustable bar assembly and rigid supporting pole portions. The horizontal bar is vertically adjustable by selectively unclamping and sliding the bar along the vertical bars. The apparatus may be adjusted and secured in various positions for singular or combined use with the treadmill. The mounting means of the apparatus to frame portions of the treadmill allows for easy disassembly and storage of the apparatus in a closet or under a bed.

A jungle gym joint has a joint main body including joint shafts to which pipes are connected and rotary members. The pipe is connected to one end and a folding portion is formed at the other end of the rotary member, the folding member being formed by a flat plate portion being held in a bifurcate portion together with the joint main body. A cover member including engaging projections on an inner circumferential surface is provided on an outer circumference of the folding portion. The cover member is guided to move back and forth in an axial direction by the engaging projections being brought into engagement with guide grooves. The folding portion is restricted from being folded with the cover member staying in an advanced end position while the restriction of folding thereof can be released with the cover member staying in a withdrawal end position.

An exercise device includes a frame having a width and a length and defining a first opening extending in a direction perpendicular to the width and the length. The first opening is sized to retain at least a portion of a weighted object therein such that the width and the length of the frame extends along at least a portion of a width and a length of the weighted object, respectively, and externally thereto when the frame is connected to the weighted object. A handle member is connected to the frame to be gripped by a user.

An exercise device, having a pair of supports that rest upon a ground surface and a bridge that extends between the supports and is elevated above the ground surface. The supports each include an upper support that includes an upper tube and a lower support that includes a central post that together telescope so as to adjust the height of the bridge. Handgrips are selectively attachable to the bridge for allowing the user to perform various exercises. Attachment plates secure each end of the bridge to one of the upper tubes. The lower supports are each T-shaped, including a base member and each have a pair of lateral supports that are deployable to stabilize the base members from side movement.

An exercise apparatus has at least one vertical wall structure, a floor and a ceiling forming a cage that can be square, rectangular, circular, oval or another suitable configuration. An arrangement of strategically placed attachment points on the wall structure, floor and ceiling enables easy attachment and detachment of a variety of resistance devices (e.g., a handheld and/or inline cable operated resistance creation device, or a stretch band resistance device) to any of the vertical and/or horizontal structures within the gym cage, thereby providing a nearly 360 degree dimensional point of resistance to perform a wide variety of exercises for different muscle groups and subgroups of the body. In one embodiment, the cage includes an arrangement of spaced apart vertical and horizontal frame members forming a rear wall and opposite side walls.
