The present invention relates to a muscular exercise equipment. In particular, the muscular exercise equipment comprises: a first module comprising an upper support bar, and upper connecting rods connected at both ends of the upper support bar; a second module comprising a lower support bar, and lower connecting rods connected at both ends of the lower support bar; and a central support bar coupled to ends of the upper and lower connecting rods, wherein stepped portions are formed so that the ends of the upper connecting rods and the lower connecting rods are coupled so as to face each other, and the central support bar is disposed at an area in which the stepped portions are coupled, and a tension ring configured to provide an elastic force in an opposite direction to a rotating motion of at least one of the first and second modules using the central support bar as an axis is inserted in and disposed at the stepped portion of the upper connecting rods.

A treadboard of a treadmill, the treadboard comprises two first elastic strips (1) of same structure and a plurality of solid support strips (3); the first elastic strips (1) are arc structural, either end of each first elastic strip (1) is once formed with buffer portion that is flexible along the length direction, so that the buffer portions buffer the arc structure of the first elastic strip (1) after fixedly connected to the base of the treadmill; the solid support strips (3) are respectively connected vertically between the two first elastic strips (1), two ends of each solid support strip (3) are respectively connected to the corresponding upper sides of the two first elastic strips (1). And a treadmill of with the treadboard. The treadboard improves the exercise comfort when a running man runs.

The present invention relates to muscular exercise equipment. In particular, disclosed is a muscular exercise apparatus comprising: an upper support bar, which has a certain length and on both sides of which connecting rods are disposed; a lower support bar, which has a certain length and on both sides of which connecting rods are disposed, wherein the connecting rods of the upper support bar and the connecting rods of the lower support bar are fastened to each other such that the upper support bar and the lower support bar have a certain angle therebetween; and a central support bar for supporting the bending motion of at least one of the upper support bar and the lower support bar.

The facial muscle exercising device (20) is provided with an elastically deformable bending portion (21) and a mouth-held portion (24), which is installed at the center of the bending portion (21) and held by the lips. The mouth-held portion (24) is located outside an edge portion of the bending portion (21).

Barbell with collateral resistance of embodied springs which consists of four resistance springs (2), two cylindrical handgrips (3), three closure washers (4) and one bar (1).

Alongside any exercise which can be performed with the collateral resistance embodied springs Barbell, the user, via the cylindrical handgrips (3), can compress- coil up the resistance springs (2) inwards (α) or outwards (β) resulting in training more muscle groups of their body simultaneously.

The subject of this invention is a device for evaluating and training the respiratory muscles in humans using a dual-mechanism threshold opening valve for the imposing of both inspiratory and expiratory loads, comprising a cylindrical casing with a central common chamber joined to two end chambers -inspiratory and expiratory - by means of the fixed part (6) of two internal equidistant membranes while the moving part (7) of each membrane connects to the end chambers with an regulating control part (5). This fixed part is a disc with flow-through vents facing the moving part, arranged in a disc of lesser thickness that extends to a central appendix joined to a tensioning element (8), which links to the regulatory control part. The central chamber has a vent of considerable proportions connected to an intake nozzle (3) for the user to inhale/exhale air and the inspiratory and expiratory chambers have vents for air to enter and exit.

An abdominal exerciser has base and back frames pivotally mounted for movement between upright and recumbent positions, and a seat frame with cushion rotatable on the base frame. A low friction journal between the base and seat frames supports a user's weight. The journal is about 30 to 42% the distance from a rear end of the cushion to its front end so the user's coccyx is vertically aligned with the journal. Arms at each side of the base frame have a pair of extensions connected to either the base or seat frame, each with a U-shaped handhold lying in a plane at an acute angle of about 30 to 80 degrees to the horizontal. A pair of single pulleys or a pair of tandem pulleys are mounted near the rear of the base frame and are engaged by sleeve-covered springs for biasing the back frame toward the upright position.

A gymnastic equipment (1) comprising a frame (10), a load group (20) carried by the frame (10) in a given manner; the load group (20) comprising an elongated elastic body (30) connected to the frame (10) and a flexible member (40) connected to the elastic body (30) in a given manner; the elastic body (30) comprising an arch (30) delimited by two respective end portions (32)(33), each of which being designed to couple with the flexible member (30) in such a manner as to maintain this latter tensioned both at rest and in use, during the execution of a training exercise.
