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.

A supporting device for users of a Pilates exercise machine to maintain the user at an inclined angle upon the platform or carriage of the exercise machine during use. The supporting device features a body having a bottom adapted for positioning on the moving or stationary carriage of the Pilates machine and an inclining top surface to support the body of the user inclined. A first and second side space formed on opposing sides of a narrowed portion of said top surface provide respective spaces for positioning of the arms of the user therein.

Controlling an exercise machine includes receiving a stream of measurements of extension of a component of an exercise machine. It further includes characterizing the stream of measurements including detecting at least one extremum having at least one extremum parameter. It further includes matching the extremum parameter with a previously determined signature associated with a user. It further includes changing an output of the exercise machine based at least in part on the match.

Controlling an exercise machine includes receiving a stream of measurements of extension of a component of an exercise machine. It further includes detecting a first phase of a repeated motion. It further includes detecting a transition to a second phase of the repeated motion. A time constraint is applied to the detection of the transition to the second phase of the repeated motion. It further includes controlling a resistance associated with the second phase of the repeated motion.

A shoulder strengthening apparatus includes a base, a shaft having a distal end portion and a proximal end portion pivotably coupled to the base, a hand rest coupled to the distal end portion of the shaft such that the hand rest is configured to move with the shaft relative to the base, and a resistance mechanism configured to restrict movement of the shaft relative to the base.

An exercise machine tension device securing system for safely and efficiently securing selectable biasing members to an exercise machine. The exercise machine tension device securing system generally includes an exercise machine including a frame and a carriage movably positioned on the frame. A plurality of tension devices may be connected to the frame at one end; with the other end being removably connected to the carriage by a selection device. The selection device may include a plurality of slots for removably receiving one or more of the tension devices to secure the tension devices selectively to the carriage. A securing member movably connected to the selection device includes projections adapted to selectively enclose the slots so as to secure the tension devices within the slots of the selection device.

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.

An exercise machine with a slidable carriage and accessories providing for a plurality of exerciser positioning surfaces and gripping handles. The exercise machine generally includes one or more lifting handles for raising or lowering either end of the exercise machine with respect to a ground surface. The exercise machine may also include a plurality of wheels each including a ridge adapted to engage with a corresponding groove in a track of the exercise machine. The exercise machine may also include a handle including a pair of arms which are positioned at a distance just greater than a width of the carriage.

A limb exercise machine includes a first transmission unit and a second transmission unit. A left-hand control member, as well as a right-foot control member, is connected to the first transmission unit. The left-hand control member and the right-foot control member are pulled by the first transmission unit to be moved synchronously. A right-hand control member, as well as a left-foot control member, is connected to the second transmission unit. The right-hand control member and the left-foot control member are pulled by the second transmission unit to be moved synchronously.

A trampoline includes a bounce fabric, a plurality of fabric clamps and a fixed frame. The bounce fabric is connected to the fabric clamps, and one end of the fabric clamp is connected to one end of a spring. The fixed frame includes connectors and frame grooved pipes. The surface of the frame grooved pipe is provided with a grooved-pipe horizontal channel, and the other end of the spring is connected to the grooved-pipe horizontal channel on the surface of the frame grooved pipe. The connector is provided with a grooved-pipe connecting end and a support-pipe connecting end. The inner side of the grooved-pipe connecting end is provided with a through hole, and the surface of the grooved-pipe connecting end is provided with a groove. One end of the frame grooved pipe is arranged in the through hole. The groove is arranged in the grooved-pipe horizontal channel.
