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.

A crank-driven exercise device (100). The crank-driven exercise device (100) includes a frame (102), a spindle (202) rotatably connected to the frame (102), a crank arm (104) connected to the spindle (202), and a user input (208) connected to the crank arm (104) configured to receive a force from a user. In some embodiments, the crank arm (104) includes a proximal section (204) and a distal section (206). The proximal section (204) may be connected to the spindle (202) at a spindle interface (302), the distal section (206) may be rotatably connected to the user input (208) at a user input interface (306), and the distal section (206) may be selectively fastenable and selectively rotatable relative to the proximal section (204) at a crank interface (304).

An exercise apparatus and method for rotational and vertical movement, the exercise apparatus including a base with a stabilizing foot extending substantially perpendicular to the lengthwise axis, further included is a support beam having proximal and distal end portions, wherein the proximal end extends from the base. Also included is a suspension handle that is disposed adjacent to the distal end and a pivotally attached platform attached to the base. Wherein operationally, on the exercise apparatus an individual standing on the platform can simultaneously grasp the suspension handle to initiate a whole body twisting motion via a pivotal movement of the platform situated as between the suspension handle and the pivoting platform with the ability to add a pull up exercise using the suspension handle, wherein the suspension handle provides added stability and support to the individual for effecting a soft skeletal joint vertical support that is variable at will.

An elliptic-orbit treadmill has a front-end drive portion and a middle drive portion configured on the front end of the pedal, the middle drive portion being pivotally linked to the bottom end of the handle bar on the same side. Each transmission bar set includes a transverse connecting rod and a vertical connecting rod pivotally connected to each other in an elbow style, the rear end of the transverse connecting rod being pivotally connected to the middle section of the handle bar on the same side, while the bottom end of the vertical connecting rod being pivotally connected to the front-end drive portion of the pedal on the same side. The crank provided on the transverse driven shaft at the center of the flywheel is pivotally connected to the middle section of the transverse connecting rod provided on the transmission bar set on the same side.

A multiple position locking handle for an exercise machine for that is movable into a plurality of different positions when unlocked and that is retained in a single secure position when locked. The multiple position locking handle for an exercise machine generally includes a tubular base having a lower end and an upper end, an elongated member extending through the opening of the upper end of the tubular base and extending downwardly through at least a portion of the tubular base, a handle extending outwardly from the elongated member at an angle, and a locking device. The elongated member is movable within the tubular base when the locking device is in the unlocked state and is substantially not movable within the tubular base when the locking device is in the locked state.

An apparatus for human exercise in certain configurations includes first and second foot pads attached to first and second guided carrier members, respectively. A first curved guide rail portion is coupled to the first guided carrier member, and prevents motion of the first guided carrier member except for translation along the first curved guide rail portion. A second curved guide rail portion is coupled to the second guided carrier member, and prevents motion of the second guided carrier member except for translation along the second curved guide rail portion. A first motion resistor is coupled to the first foot pad and opposes a translation of the first foot pad along the first curved guide rail portion. Each of the first curved guide rail portion and the second curved guide rail portion is curved away from an underlying ground plane, to define a distally increasing rail height.

A safety control system for use with an exercise apparatus utilizing a one-way clutch includes a rope wrapped around a spindle driven by a motor. A controller is capable of applying a brake when power loss is detected by an internal circuit to ensure the safety of the apparatus and user.

A golf swing training device generally guides and trains a golf swing with a particular focus on weight transfers and hip rotations throughout the golf swing. The device includes a baseboard that provides a bottom fulcrum which aids an athlete in training a correct weight distribution throughout the golf swing. A pedal assembly, which includes a front pedal and a back pedal (corresponding to front/back feet), engages with a top fulcrum to aid the athlete in training correct hip rotation throughout the golf swing.
