Abstract: An exercise pedal includes a plate member including a receiving cavity fixed on a bottom surface thereof, with the receiving cavity including a plurality of partitions to space a number of recesses. A seat formed in a semicircle shape is retained to the recesses to be horizontal or to be vertical either upside down or right side up according to the demands of the user, such that the plate member and two seats are capable of being used solely or together to vary exercise motions. Furthermore, the seats are placed in the first recesses of the plate member to reduce storing size and to be portable easily.

Abstract: An adjustable exercising device includes two grip members, each including a lateral coupling seat having a plurality of inserting holes disposed on a front end thereof and an engaging device mounted thereon. Each of a plurality of resilient straps has a connector fixed on each of two ends thereof. Each connector includes an engagement slot or engagement bore arranged on one side thereof, so that the connectors are inserted to the inserting holes to be retained by the engaging device.

Abstract: An exercise pedal comprising: a plate member including a receiving cavity fixed on a bottom surface thereof, and the receiving cavity including a plurality of partitions to space a number of recesses; a seat formed in a semicircle shape to be vertically, upside down or horizontally retained to the recesses based on demands, such that the plate member and the two seats are capable of being used solely or together to vary different exercise motions. Furthermore, the seats are placed in the first recesses of the plate member to lower storing size and be portable easily.

Abstract: A gymnastic apparatus, comprising two handle assemblies and a flexible strengthening springy belt, wherein the handle assembly including a main body having a handle, a groove room is defined in the main body, a cover is connected to the groove room, an opposite clipping members are mounted in a inner surface of the groove room and the cover for positioning the strengthening springy belt, and a scroll is mounted in the groove room for rolling the redundant strengthening springy belt. Thereby the length of the strengthening springy belt can be adjusted according to the requirement, and stretching the strengthening springy belt through the handle assemblies can attain the effect of keeping fit.

Abstract: A twister and sit-up combination exerciser has a base, two V-shaped levers each having a front end with a grip and a read end, a supporting frame adjustably attached to the rear ends of the levers, and at least one twister rotatably mounted on the base. The two V-shaped levers are pivotally attached to the base to provide a sit-up auxiliary structure. By combining the twister with the sit-up auxiliary structure, the exerciser has at least two functions. Moreover, the base further has a base twister rotatably attached under the base to make the exerciser have more versatility in use.

Abstract: A unit of a flection exerciser is made of resilient and durable plastic material in one-piece. Two ends of the flection exerciser are two enlarged grip portions and has an extension portion connected the two ends. The two grip portions have a pin joint and a box joint respectively, wherein each joint is a cylindrical body with two annular flanges at two ends and a slot longitudinally in the cylindrical body. The pin joint has an insertion formed at a distal surface thereon and the box joint has a corresponding insertion hole defined at a distal end thereon. By having the pin joint and the box joint, the unit conveniently connects with other same units to elongate or loop to perform the flection exerciser in various types.
