A workout system is provided that includes a piece of furniture having at least a backrest and a seat. A chair workout machine is provided coupled to the piece of furniture. The chair workout machine includes a support frame coupled to at least one structure of the piece of furniture. At least one rotatable arm is rotatably attached to the support frame. One or more resistance elements are coupled to the at least one rotatable arm, where the resistance elements arranged to provide resistance to movement by at least one body part of a user.

A training guidance instrument 200 includes a pressor part 2091, a heel placing part 2092A, and a control unit including rotary members 210 and 214, support members 211 and 215, rotary parts 202A and 202B, support members 212 and 216, and telescopic members 219 and 220. The control unit is configured to move the heel placing part 2092A toward the ground in response to application of a force Pw2 toward the ground which is stronger than upward force applied on the heel placing part 2092A when the heel placing part 2092A is positioned above and away from the ground and move the heel placing part 2092A upward in response to application of weaker force toward the ground than the force Pw2 on the heel placing part 2092A, while the second joint and third joints of the toes of the trainee are pressed by the pressor part 2091 and the heel is placed on the heel placing part 2092A.

The present invention relates to a multi-functional exercise apparatus, and particularly to a multi-functional exercise apparatus which is safe and allows various exercises with different setups to be performed by means of a single apparatus. The present invention, relating to a multi-functional exercise apparatus provided so as to impart a sense of stability to a user when exercising while at the same time allowing various exercises with different setups to be performed by means of a single apparatus, comprises: a plate-shaped body (A) forming the floor surface and having a space in the interior thereof; fixed frames (100) fixedly disposed upwardly on both sides of the body (A); rotatable frames disposed upwardly on both sides of the body (A); handle parts (200) connected on one side of the rotatable frames and provided so as to be movable forwards and backwards; and a foot plate part rotatably provided on upper surface of the body (A) and connected to the other side of the rotatable frames. The multi-functional exercise apparatus according to the present invention imparts a sense of stability to a user as the rotatable frame comprises a plurality of linked sections and connects the handle parts and foot plate part, allowing the user to exercise by rotating not the entire rotatable frames but only the handle parts which are comparatively short compared to the rotatable frames. Furthermore, each linked section of the rotatable frames is rotatably attached to the handle part or to the side of the fixed frame, allowing the rotatable frames to stably transmit driving power from the handle parts (200) to the foot plate part and to be changed so as to allow various exercises with different setups to be performed.

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).

A hip thrusting exercise machine is an apparatus that allows a user to safety perform a hip thrusting exercise in a controlled manner. The apparatus includes a backrest, an abdominal brace, a feet brace, an elongated frame, and a recoiling mechanism. The feet brace and the back rest allows the apparatus to properly hold the user's body in place while the user is performing the hip thrusting exercise. The abdominal brace is pressed against by the user's pelvic region in order to perform the hip thrusting exercise. The recoiling mechanism provides the user with physical resistance as the user pushes to raise the abdominal brace from a resting position to a vertically higher position. The coiling mechanism also returns the abdominal brace from the vertically higher position to the resting position so that the user can repeat the hip thrusting exercise.
