A device that exercises the muscles of a person who lays down on a bench (12), by the person shifting his body to counteract a tendency of the bench to tilt to one side or the other. The bench is supported on coil springs (44) that tilt when the person's weight shifts to one side as the person performs exercises while laying on the bench.

An exercise apparatus or machine according to the present disclosure is adapted to support a user above a floor while the user performs hip thrust or other exercises. The exercise machine includes a head support and a foot support for supporting the torso and feet of a user so that the hips of the user are suspended in an exercise area between the head support and foot support.

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.

Disclosed is a multifunctional muscle exerciser comprising two handles (1, 2). The two handles (1, 2) each comprise a connection end (1a, 2a) and a grip end (1b, 2b). A torsional spring (3) is connected between the connection ends (1a, 2a) of the two handles (1, 2). The torsional spring (3) is composed of stacked multichip spring steel pieces (31). The two ends of the multichip spring steel pieces (31) are respectively connected via fasteners. Preferably, both of the two handles (1, 2) are U-shaped. The connection ends (1a, 2a) of the two handles (1, 2) are coaxially arranged. The grip ends (1b, 2b) of the two handles (1, 2) are in parallel but are not on the same straight line.

An abdominal exercise apparatus can include a track, at least one rolling member, a cart, and a base. The track can extend between first and second ends. The rolling member can be moveable along the track. The cart can support the rolling member for the movement along the track and be grasped by the user during exercise. The base can be engaged proximate to the first end and have a surface configured to receive the knees of the user during exercise. The second end can be pivotally movable about the base over an arcuate range by the user while exercising during the rectilinear and rolling movement along the track by the at least one rolling member. The apparatus can also include a structure such as a helical spring for resisting pivotal movement that is elastically deformable.

The present invention relates to an exercise machine that has all the functionality of a standing, bulky, multifunctional exercise machine, but can be mounted on a door frame so that it can quickly and conveniently change from full exercise functionality to full doorway functionality without any removal or disassembly of any components.

An apparatus for performing abdominal exercises, the apparatus comprising a frame (10) for providing a stable base for operation of the apparatus, a seat (14) for a user to rest onto, a resistance adjustment means (20) for adjusting level of resistance for operation of the apparatus and a joint mechanism (22) for bearing loads and providing rotational movement, wherein the resistance adjustment means (20) is operable to resist movement of the joint mechanism (22) located at centre point of the frame (10), characterized in that an arm (16) connected to the joint mechanism (22) located at centre point of the frame (10) is rotatable at centre point of the frame (10) by means of the joint mechanism (22) and the seat (14) is linearly connected to the arm (16) and is linearly traversable about the arm (16) and the seat (14) is further rotatably connected to the arm (16).

Disclosed is a backbone retraction apparatus which includes a support member supporting a hip of a user, a center member coupled to the support member by a hinge structure, a backrest member inserted into the center member, a neck support member inserted into the backrest member, moving means comprising a wire having a first side fixed to the center member and a second side fixed to the neck support member and a first latching protrusion protruded from the backrest member and adapted to have the wire hung on the first latching protrusion, the second side of the wire being fixed under the first latching protrusion, and length adjustment means adapted to be connected to the support member and the backrest member.

A fitness apparatus for enabling numerous different fitness routines on a single piece of apparatus and having two side assemblies each having upright metal bars of hollow tubular construction each having fastening holes along its length, generally L-shaped junction portions of said upright bars of similar hollow tubular material and having fastening holes therealong, cross members extending between the two side assemblies holding them in spaced apart locations, floor rests on both side assemblies, a first fitness exercise attachment secured to one of the side assemblies, and, a second fitness exercise attachment, different from the first fitness exercise attachment, secured to the other side assemblies.

Disclosed herein is a dynamic pendula stool possessing a foot, a leg secured to the foot, and a seat secured to the top end of the leg. The leg has a telescopic column that includes a lower part secured to a spherical foot with a diameter of 20-cm or less and an upper part with a free end having an articulation. The articulation has three degrees of freedom and is secured to the underside of the seat so that when a user rests against the seat, the leg forms an angle between 30 and 90 degrees with respect to the horizontal, thereby allowing an isometric contraction of the muscle groups of the lower limbs and of the abdominal girdle in the seated position. The stool is further provided with one or more sensors configured to send data signals to a remote electronic device.
