An exercise workstation includes a treadmill, a pedal exercise device disposed on or next to the treadmill, and a chair pivotally secured to the exercise workstation. The chair can be repositioned relative to the treadmill, such as above or to the side of the treadmill. A pivot arm is pivotally connected to a pivot joint to permit multiple positional adjustments of the chair. The pivot joint may be connected to the treadmill in fixed or movable position. The exercise workstation may include or be positioned adjacent to one or more work surfaces, such as a height adjustable desk or table.

Tracking and monitoring athletic activity offers individuals with additional motivation to continue such behavior. An individual may track his or her athletic activity by completing goals. These goals may be represented by real-world objects such as food items, landmarks, buildings, statues, other physical structures, toys and the like. Each object may correspond to an athletic activity goal and require an amount of athletic activity to complete the goal. For example, a donut goal object may correspond to an athletic activity goal of burning 350 calories. The user may progress from goal object to goal object. Goal objects may increase in difficulty (e.g., amount of athletic activity required) and might only be available for selection upon completing an immediately previous goal object, a number of goal objects, an amount of athletic activity and the like.

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.

An exercise machine inclination device for providing variable exercise intensity on an exercise machine by inclining the exercise machine. The exercise machine inclination device generally includes a base adapted for being positioned upon a floor, a support structure adapted for supporting the exercise machine, a hinge pivotally connecting the base and the support structure and an actuator connected between the base and the support structure, wherein the actuator adjusts an angle of the support structure.

An elliptical trainer includes a machine table, a transmission unit, two pedal units and two suspension arms. Each pedal unit has a pedal rod and a guide. The pedal rod has a front end thereof pivoted to one respective crank arm, and an opposing rear end thereof pivoted to one respective pedal seat. The pedal seat has the top surface thereof bearing one respective pedal. Each suspension arm has two opposite ends of a bottom side thereof respectively pivoted to the machine table and the rear end of one respective pedal rod. Each suspension arm is skewed in the direction of the pedal, so that each suspension arm can guide the pedal forward along a straight line direction and backward along a diagonal direction.

A differential air pressure system has a pressure bag with windows and preferred folding configuration such that when the bag is folded no window is folded. The pressure bag is supported by a lift support that is proximal to a user control panel and adjacent to or nearly adjacent to the user who is coupled to the pressure bag. A treadmill base for use with differential air pressure equipment is provided. There are various improvements provided to adapt the operations of the DAP system via the use of separate pressure volume and non-pressure volume portions of the treadmill base. Various improvements to serviceability and repairs are provided by placement of components outside of the pressure volume portion or by providing one or more pressure volume access points.

An exercise device comprises a base and a rotation assembly movably attached to the base. The rotation assembly comprises an exercise interface assembly comprising at least one exercise support portion configured to be moved by a user, a crank assembly comprising at least one crank rotatably attached to the at least one exercise support portion and configured to be rotated about a crank rotational axis by the at least one exercise support portion, and a flywheel assembly comprising a flywheel configured to be rotated about a flywheel rotational axis due to rotation of the at least one crank. The crank rotational axis and the flywheel rotational axis are substantially perpendicular to each other.

An exercise machine is provided. The exercise machine may include a frame, an adjustment assembly coupled to the frame and selectively movable relative thereto, a foot linkage arranged to reciprocally move in a closed loop path, and a handle linkage arranged to reciprocally move in a defined path. The adjustment assembly may include a pivot axis. The foot linkage may be pivotably coupled to the adjustment assembly at the pivot axis such that selective movement of the pivot axis relative to the frame alters the closed loop path of the foot linkage in use. Movement of one of the foot linkage and the handle linkage may cause corresponding movement of the other of the foot linkage and the handle linkage Actuation of the adjustment assembly may selectively move the pivot axis in more than one direction.

A driving and resistance control system for a permanent-magnet synchronous motor is disclosed. A control device includes a processing unit, a motor driving circuit, a resistance controller, and an interlock switch. In a first operation mode, the interlock switch makes the motor driving circuit and the permanent-magnet synchronous motor open-circuiting, and connecting stator windings of the permanent-magnet synchronous motor to the resistance controller, and under this condition, the external rotor of the permanent-magnet synchronous motor is rotated by spinning of a flywheel, so that the permanent-magnet synchronous motor is operating in a generator mode to generate a resisting force to the flywheel by mesas of a resistance generation device. In a second operation mode, the interlock switch makes the motor driving circuit and the permanent-magnet synchronous motor closed-circuiting and cutting off control of the resistance controller, and electrical energy is supplied from the power supply circuit to the permanent-magnet synchronous motor, so as to make the permanent-magnet synchronous motor operating in a motor mode to induce an acceleration on the external rotor.

A pedal of an exerciser contains: a body and a fitting sleeve. The body includes multiple slots parallelly defined on the body, and the body includes a first slide rail and a second slide rail symmetrically formed on two sides of the body. The fitting sleeve includes a connection portion received in the multiple slots, a first rotatable seat and a second rotatable seat symmetrically fixed on two sides of the fitting sleeve. The first rotatable seat has a first receiving orifice, and the second rotatable seat has a second receiving orifice, such that a coupling bolt is inserted through the first receiving orifice of the first rotatable seat, the first slide rail of the body, the second slide rail of the body, and the second receiving orifice of the second rotatable seat. Thereafter, the coupling bolt is locked by two first defining elements and two second defining elements.
