A stationary trainer for use with a bicycle with the rear wheel removed. The stationary trainer has a fan assembly including a fan attached to a fan hub configured to rotate about a fan hub axle. The trainer has a drive assembly including a drive hub having at least one gear cog configured to connect with a chain of the bicycle for providing power to the stationary trainer, and a chain ring, the drive hub configured to rotate about a drive hub axle. The drive hub axle is configured to engage with the rear dropouts of the bicycle. The trainer has a chain drive including a chain connecting the chain ring on the drive hub to a cog on the fan hub. There is a first side panel located on a first side of the fan and a second side panel located on a second side of the fan opposite the first side of the fan. One or more bracing elements connect the first side panel to the second side panel. The fan assembly and the drive assembly are supported by the first side panel and the second side panel, and a distance between an edge of the fan blade and either the first side panel or the second side panel is in the range from 4 mm to 70 mm.

A resistance device applied to relative rotations between a flywheel and an axis includes an inner stator, an outer rotor, a conductive wire and a magneto-rheological fluid. The inner stator is fixedly joined with the axis and includes an accommodating space surrounding the axis at a position away from the axis. The outer rotor, fixedly joined with the flywheel, encloses and rotates relative to the inner stator. An accommodating gap is formed between the outer rotor and the inner stator at a position away from the axis. The conducting line is winded in the accommodating space, and generates a magnetic line passing the accommodating gap when applied by an electric current. The magneto-rheological fluid is filled in the accommodating gap. Thus, the outer rotor is disposed at the outer most to increase the braking torque, and the magneto-rheological fluid is away from the axis to increasing the braking moment.

A stationary exercise device having variable footpaths is disclosed. The exercise device includes a frame, a pair of supporting members that have a first end to rotate about an axis and a second end to move along a reciprocating path, a pair of pedals joined to the supporting members, and a guider assembly for adjusting an incline angle of the reciprocating path.

A portable exercise apparatus having a base, at least two handle assemblies, and a cable wrapped between at least one flywheel within the base, wherein the cable is attached to a handle assembly and is affixed to a spring mechanism configured to provide resistance against the pulling of the handle assemblies. The load provided by the spring mechanism can be adjusted to accommodate more or less resistance for the user. The exercise apparatus is compact and can be used in a standing or sitting position.

A stationary exercise equipment has a supporting structure, a movable user interface connected to the supporting structure, and a force-resisting device. The force-resisting device with a hub mounted continuously variable transmission configured therein provides a variable resistance force that varies an amount of force with a movement of the movable user interface. The hub mounted variable transmission is operably to vary the resistance force of the movable user interface in a manner of varying a rotational rate of the user interface to increase or decrease as required.

An exercise apparatus providing a User multiple different exercises, including both resistance movements and isometrics. The User interacts with the apparatus by grasping a bar. A resistance mechanism is symmetrically mounted on a second bar and provides infinitely variable resistance to the User, as well as soundproof operation. A vertical column allows infinite positioning of the bars for different exercises, and a bench provides support. The User can change the exercise resistance by verbal commands, or the apparatus can sense the torque applied by the user to the apparatus and vary the exercise resistance in response to the force applied by the User or the speed at which the user is moving the bar. The apparatus can be battery powered and operated at locations where electric service is unavailable, or in zero gravity. To verify accuracy, the resistance can be calibrated against a known quantity of weight.

An inflatable belt 100 for use in a BFR system with an outer belt material 102 hermetically sealed to an inner belt material 101 along a perimeter, thereby forming at least one inflatable chamber 103, the inflatable chamber having an input port 104 for accepting a gas into the chamber, the inflatable belt further comprising a first fastening means 110 in communication with the outer belt material, for attaching to a second fastening means 111 in communication with the outer belt material, thereby locking a circumference of the inflatable belt, when wrapped around a user's limb, efficacy feedback means 200 for gathering efficacy feedback data 205, for use in prescribing, monitoring and adjusting one or more training parameters of a BFR training session and/or program based on evaluation of the efficacy feedback data.
