A bi-directional exercise machine has a work arm, first and second cams coupled to the work arm, a resistance mechanism, and a pulley assembly that couples the resistance mechanism to the work arm via the first and second cams so that movement of the work arm is resisted by the resistance mechanism according to first and second resistance profiles provided by the first and second cams, respectfully. A primary pulley cable has a first end coupled to the first cam and a second end coupled to the second cam. When the work arm is in a rest position, the ends of the primary pulley cable extend from cable tracks of the cams, respectively, at a tangent so that the resistance mechanism applies a resistance force on the work arm via the pulley assembly immediately upon movement of the work arm out of the rest position.

A training apparatus includes a fixed frame, a training rod, a motor, rotation information detection sensor, tilt angle and position difference calculation units, determination, motor drive and position difference eliminating units. The training rod is supported by the fixed frame in a manner capable of being tilted by a motor about at least an X-axis or a Y-axis so as to hold the limb. The tilt angle calculation unit calculates a tilt angle of the training rod. The position difference calculation unit calculates a position difference. The determination unit obtains the position difference every time when a second time period elapses. If the position difference generated in the second time period is a first threshold or lower, the motor drive unit drives the motor so that the position difference is accumulated and maintained. The position difference eliminating unit resets the position difference at a predetermined timing.

A portable single bicep exercising machine is disclosed. The machine may comprise articulable framework running about a length of a user's given arm. This framework may be divided into upper framework and lower framework, with an articulable fulcrum connecting the upper framework to the lower framework. In use the upper framework, at an under arm pad, may be retained in a user's should/armpit region; while the lower framework may comprise a handle to be engaged by the user's hand of that same arm. Also between this upper framework and this lower framework may be one or more tension means, such that when the handle is articulated towards the under arm pad, about the fulcrum, that articulation is through resistance. It is such resistance that exercises the bicep of that same given arm.

An exercise rack pulley system for providing a wide range of versatile arrangements of pulleys on an exercise rack. An example embodiment generally includes an exercise rack including one or more support members and arm members. One or more pulley units may be attached to one or more support members and/or arm members of the exercise rack. Each of the pulley units includes a bracket for attaching to the exercise rack and a frame for supporting a rotatable pulley. The frame is adjustably connected with the bracket such that each pulley unit may be adjusted between at least two positions, including a first position in which the frame is parallel with the bracket and a second position in which the frame is perpendicular with the bracket. A cable is routed through the pulley units and connected to a weight to accommodate a wide range of different types of exercises.

A fitness device contains a strap, a handle, and a plate. The strap is substantially inelastic and flexible. The plate is substantially rigid. The handle at least partially envelopes the strap. A method of exercising with such a fitness device is also described herein. Other fitness devices and other methods of use are also described herein.

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 portable exercise apparatus utilized for exercising, stretching, and training multiple muscle groups of the body of a user. The apparatus is adapted to be worn about the waist or carried as a bandolier about the user's body. The apparatus has at least one releasably closable pocket and fixation rings for securing and carrying accessories, such as attachable handles, suspension lines, and elastic bands. The apparatus and methods of use provide the user with a plurality of configurations for assisted exercise regimens and the flexibility to exercise anywhere.

An ideal target weight training recommendation method ascertains a user's ideal target weight with a user-data algorithm that is operable to approximate an available weight value for a user to utilize for a given target weight training recommendation in addition to generating a rate in which a user's muscle fatigues. To do so, the user generates initial completed repetitions until the muscles fatigue. A baseline strength value is calculated with the initial completed repetitions and a baseline strength coefficient. A baseline strength value is created and used in calculating ideal target weight values. A y-intercept approximate functions involving user-selected desired target repetition values. The user manipulates a resistance structure associated with the ideal target weight values and said values are rounded to the nearest whole number. The user-selected desired target repetition values generate a second completed repetition values for subsequent sets for adjustment of a strength curve.

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.
