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.

An exercise device of the type including a frame with a first crank assembly rotatably coupled to the frame about a first axis and a second crank assembly rotatably coupled to the frame about a second axis. A control system may be used in communication with the first crank assembly and the second crank assembly, which may provide a synchronous movement of the first crank assembly relative to the second crank assembly. A pedal arm may be provided with a first end pivotally coupled to the first crank assembly and a pedal positioned on a second end. A crank link may be used with one end coupled to the second crank assembly and a second end coupled to the pedal arm. The crank link may be movable on the pedal arm which may provide varying paths of motion of the pedals.

An integrated fitness system including a slidable unit that is slidably attached to a column vertical to the ground and that has exercise units mounted thereon. The exercise units are disposable in any of a plurality of configurations and have arms that are rotatable in any of a plurality of planes. The exercise units can be positioned along the column at any of a plurality of heights by sliding the slidable unit along the column to allow a user to use the exercise units for both arm and leg exercises.

An exercise machine is provided with a loading device. The loading device includes a lever, a coupler, a cylinder unit and a driving unit. The lever includes two ends. The first end of the lever is connected to the exercise machine. The coupler is movable along the lever between the first and second ends. The cylinder unit includes an end connected to the exercise machine and another end connected to the coupler. The driving unit includes a threaded sleeve, a threaded rod and a motor. The threaded sleeve is connected to the coupler. The threaded rod is engaged with the threaded sleeve. The motor rotates the threaded rod relative to the threaded sleeve so that the threaded rod moves the coupler via the threaded sleeve.

Disclosed herein is an exercise machine that includes an elongated frame having a head end and a foot end, and a moveable carriage slidably coupled to the elongated frame and moveable between the head end and the foot end, the moveable carriage having a spring bracket coupled to an underside of the moveable carriage. The exercise machine also includes a spring support rod slideably coupled with the elongated frame and disposed adjacent the foot end, and selectively positionable with reference to the foot end by a handle that extends from an interior area of the elongated frame to an exterior area of the elongated frame. The exercise machine also includes at least one resistive member coupled at a first end with the spring support rod and at a second end with the spring bracket, and configured to bias the moveable carriage towards the foot end of the elongated frame.

Improved designs for exercise machines that facilitate muscle development and other therapeutics are disclosed. The machine includes a frame, a pulley assembly, and cable extending through the pulley assembly. The cable has attachments, including an attachment for connecting to a pull handle. The cable is also connected to a selectively variable moveable resistance unit. This unit is structured to provide an elastic resistance when a pulling force is applied to the pull handle. The unit is connected to the cable and includes an elastomeric body that provides the elastic resistance and also includes an arc plate that provides a curved support member on which a portion of the elastomeric body at least partially wraps around. Movement of the arc plate causes the elastomeric body to stretch and to provide the elastic resistance.

The invention relates to an improved device for suspension training, having a central pulley which is secured by a carabiner with a safety closure and through the channel of which slides an 8 mm cord restricted by sliding cord loops into which are hooked flat carabiners that connect same to handles formed by a flat strap and a tube with a cushioned surface, the device also having a strap of loops.

An exercise apparatus for assisting a user with a range of exercises includes a frame having a first frame section extending in a generally horizontal direction. At least one carriage is configured to support a user, wherein the carriage is slidably supported on the first frame section. A first resistance system has a first resilient member removably connected to at least one of the carriage and/or the frame. The displacement of the carriage relative to the frame exerts a tensile force on the resilient member. A second resistance system includes a load moveably mounted with respect to the frame and an actuation member connected to the load. The actuation member is configured to displace the load when a force exerted by the user on the actuating member exceeds a predetermined threshold representative of the load.

An exercise machine may include a frame, a resistance mechanism supported by the frame, first and second pull cables supported by the frame and linked to the resistance mechanism, a power rack attached to the frame, first and second handles selectively attachable to the first and second pull cable, and first and second pulleys. The power rack includes upright posts configured to have barbell holders adjustably attached thereto such that the barbell holders are configured to be adjusted in various positions between highest positions and lowest positions on the upright posts. The pulleys are configured to selectively receive the pull cables to enable the pull cables to be selectively attached to a barbell to assist or hinder a user in lifting the barbell in a combined cable and free weight workout, the pull cables decoupled from the pulleys for cable workouts.

An apparatus is provided for use in resistance training. The apparatus may include a bar with pulley hubs on its ends. The apparatus may further include two slings, each including connectors and a rigid, straight or arc-shaped bar. The slings may be suspended from the pulley hubs and support an elastic band, which may provide resistance during exercise. A footplate may also be provided to hold part of the band to the floor during use.
