An exercise machine, such as indoor cycle, includes a multi-function wheel brake actuator. A braking force is induced on a wheel by finely or coarsely adjusting the brake actuator. The brake actuator may include a knob whereby a user may finely adjust the braking force on the wheel and a lever to actuate interval settings whereby the brake actuator provides set positions of braking resistance. The lever may include a spacer to reduce friction of the lever. The exercise machine may further include a pop-pin assembly with an over-center cam mechanism to clamp members together. The pop-pin assembly also includes a fine adjustment to adjust the clamping force. Implementations of the pop-pin assembly may be arranged to apply the clamping force by pivoting a lever of the pop-pin assembly either toward or away from the members being fixed.

A bicycle trainer, the bicycle trainer comprising a biased, pivot mounted belt for contact with the rear wheel of a bicycle, such that the belt moves in response to rotation of the wheel and applies predetermined tension.

An assembly for active and resistive joint rehabilitation exercises enables a joint, such as a knee, to flex in a controlled, curvilinear motion, while enabling adjustable resistance. In this manner, the joint practices both resistive exercises and active exercises for strengthening, as well as redeveloping range of motions. A base member with stabilizing bars provides lateral support for the assembly. The base member has a recessed docking region. A bracket detachably attaches in the docking region and joins the rails to base member. In this manner, the rails can detachably release from the base member. A lever and a base handle enable assembly to be moved and tilted. A vehicle comprises wheels that ride the rails while the foot rests therein, so that joint extends and retracts the curvilinear motion. An adjustment member increases and decreases friction coefficient between the wheels and rails for adjustable resistance of curvilinear motions.

Various embodiments related to a recumbent therapeutic and exercise device are provided herein. The recumbent therapeutic and exercise device includes a frame; a hand crank system coupled to the frame, the hand crank system including a hand crank rotatable by a user, wherein the hand crank is movable in a substantially vertical plane closer to and further from a support surface for the frame; and a foot crank system coupled to the frame, the foot crank system including a foot crank rotatable by the user, wherein the foot crank is movable in a substantially horizontal plane relative to the support surface for the fame.

The present disclosure relates to a grip apparatus for exercise equipment, the grip apparatus comprising: a first annular member having a first annular sidewall and a first flange extending radially inwardly from the first annular sidewall; a second annular member having a second annular sidewall and a second flange extending radially inwardly from the second annular sidewall, a diameter of the second annular sidewall being less than a diameter of the first annular sidewall, the second annular member being positioned within the first annular member whereby the first annular sidewall, the second annular sidewall, the first flange and the second flange define together an annular chamber; a handle member connected to the second annular sidewall; and a bearing in the annular chamber, the first annular sidewall frictionally engaging a first race of the bearing and the second annular sidewall frictionally engaging a second race of the bearing.

Systems and methods are presented for performing exercises to strengthen, e.g., the transversus abdominis and related muscles. The systems and methods may involve one or more independent belts, allowing a full range of continuous motion. The systems and methods may further use a resistance-control mechanism that allows a user to adjust the force required to move the one or more belts, thereby controlling the rate of motion in the forward and/or backward directions. The systems and methods may further use a unidirectional resistance mechanism that allows the user to increase the resistance of the one or more belts in one direction, while allowing the one or more belts to move freely in the other direction.

A treadmill may include a deck, a first pulley incorporated into the deck, a second pulley incorporated into the deck, a tread belt surrounding the first pulley and the second pulley, a motor in mechanical communication with at least one of the first pulley and the second pulley to move the tread belt in a first direction, and a runaway mitigation mechanism in at least indirect mechanical communication with the motor. The runaway mitigation mechanism at least mitigates a motor runaway condition.

An exercise machine includes a frame, a first rotary mechanism supported on the frame, a second rotary mechanism rotatably engaging with the first rotary mechanism, and a driving mechanism operatively coupled to the second rotary mechanism and configured to impart rotation of the second rotary mechanism while the driving mechanism is being actuated. The second rotary mechanism is hubless. The second rotary mechanism is configured to absorb and retain an amount of the actuation of the driving mechanism as a moment of inertia while the second rotary mechanism rotates.

Embodiments allow the application of a settable and/or a programmable resistance to a trainee's leg Drive Phase and/or Recovery Phase while walking or running over extended or infinite distances. Multiple mechanical or electrical feedback loops or combinations of both to monitor the applied resistance to the Trainee by the tether or tethers and then control the amount of breaking (drag) or propulsion created by the Mobile training module during the acceleration and constant speed training phases to accurately generate, control and transfer resistance through the elastic tethers to the Trainee. Embodiments apply multiple, non-varying loads or programmable loads to multiple body parts of a trainee where applied resistance can be manipulated to both increase or decrease over distance as desired by trainee while the trainee is walking, running or sprinting over any distance.
