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 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.

An exercise machine resistance adjustment system for providing an exerciser the ability to immediately adjust the resistance force by changing their body position on the movable carriage or end platforms. The exercise machine resistance adjustment system generally includes a frame, a carriage movably positioned on the frame, a spring connected to the carriage to apply a biasing force to the carriage, one or more left projections within the carriage adapted for a left hand of an exerciser to grasp, and one or more right projections within the carriage adapted for a right hand of an exerciser to grasp. The exerciser is able to efficiently adjust the amount of resistance force applied to the carriage by repositioning their hands (or feet) from a first set of projections at a first distance to a second set of projections at a second distance from the first end of the exercise machine.

An exercise machine is for performing a striding exercise motion. The exercise machine has frame; first and second pedal members; first and second foot pads on the first and second pedal members, respectively, each of the first and second foot pads being configured to move in an elliptical path during the striding exercise motion; first and second rocker arms pivotally coupled to the frame; and first and second adjustment devices configured to actively adjust and set a position of the first and second pedal members relative to the first and second rocker arms, respectively, which thereby changes a shape of the elliptical path.

A pilates reformer machine has a frame with a longitudinal central extruded spine (2) extending between a first support member (4a, 4b) and a second support member (6a, 6b), a carriage (8) supporting a platform (9) moveable along the spine, at least one retention spring housed within the spine and attached to the carriage, the at least one retention spring being selectively attachable to the frame by buttons (12), the carriage being provided with sides that wrap around sides of the spine and engage with an underneath of the spine, the carriage further including a plurality of wheels receivable within tracks formed within the central spine. A leg exerciser (30) and foot bar (20) may be included in the machine.

A multi-functional training apparatus comprises a first floating beam, a second floating beam, a rear portion of the first floating beam being connected to a rotating member at a first point and a rear portion of the second floating beam being connected to a rotating member at a second point, the first and second points being arranged on opposing sides of a plane passing through the rotational axis of the rotating member, a forward portion of the first floating beam being connected to a lower portion of a first pivoting beam and a forward portion of the second floating beam being connected to a lower portion of a second pivoting beam, a first and second moving handle being connected to the first and second pivoting beams respectively, a first foot plate arranged on the first floating beam, a second foot plate arranged on the second floating beam.

An elliptical exercise machine may include a base, one or more upright stanchions coupled to the base and extending upward from the base and supporting first and second cranks. The first crank may support a first crank arm. The first crank arm may support a first pedal leg hanging downward from the first crank arm. The first pedal leg may support a right pedal. The right pedal may be configured to swing forward and rearward and to raise upward and lower downward. The second crank may support a second crank arm. The second crank arm may support a second pedal leg hanging downward from the second crank arm. The second pedal leg may support a left pedal. The left pedal may be configured to swing forward and rearward and to raise upward and lower downward.

An exercise bike includes a frame, a rotor assembly and a drive assembly mounted on the frame, where the drive assembly is configured to drive rotation of the rotor assembly, and a cover configured to at least partially cover the rotor assembly. The components of the drive assembly and the rotor assembly include structures that improve the performance of the exercise bike, including but not limited to a strong and rigid construction and improvements in belt tracking, user feel, effort consistency, synchronization, and rotor performance.
