The present invention relates to the field of fitness training devices and exercise machines. More specifically, a substantially horizontal exercise machine comprising an exercise platform slidable along one or more rails aligned with the longitudinal axis of the machine structure, the slidable platform spring-biased towards one end of the machine, is tiltable to allow for one end of the machine to be raised or lowered relative to the opposed end of the machine.

A rebound and balance training device includes a frame, a footboard, and a plurality of resilient spring elements extending between and attached to the frame and the footboard to support the footboard above a supporting surface. A user standing on the footboard manually effects repeated vertical bouncing movement between upper and lower positions. The distance traveled by the footboard, the effort required to effect movement, and the stability thereof may be modified by selectively modifying the number, the length, the position, or the elasticity of the resilient elements. In one embodiment, a pair of footboards is employed to simulate skiing movements.

An exercise apparatus comprises a platform having a front roller, a rear roller and an endless belt mounted around the front roller and the rear roller for allowing a user to perform a first exercise type of a relatively lower resistance or a second exercise type of a relatively higher resistance. A front frame is mounted at a front side of the platform and has at least one holding portion adapted to be grasped by the user. One or more control interfaces controls the first exercise type and the second exercise type.

A neck exercise device and system are disclosed. An implementation of the device can include a head harness having an adjustable headband and a first cranial strap having each end attached to the headband. The device can also include a second cranial strap having each end attached to the headband and an adjustable chin strap. The device can further include a plurality of attachment members.

A stepper includes a base, a linking rod, two pedals and two adjusting mechanisms. The linking rod is disposed on the base and includes two ends that are concentrically rotated with each other. Each of the adjusting mechanism includes a blocking member and a blocking block. The blocking member includes a first blocking surface. The blocking block includes at least one second blocking surface resisting the first blocking surface of the blocking member. When one of the pedals is lowered along a gravity direction, one of the first blocking surfaces and one of the second blocking surfaces are inclined along the gravity direction to link up one end of the linking rod thereby concentrically rotating the other end of the linking rod, and the other first blocking surface is resisted by the other second blocking surface thereby swinging and raising the other pedal.

A joint movement therapy and assistive device system. The system includes a torque profile device having a plurality of connecting components, a longitudinal axis, and a center. Each connecting component of the plurality of connecting components is disposed at a selected distance relative to the center and a selected angle relative to the longitudinal axis. The system also includes at least one segment end and a plurality of tensioning components removable secured to the plurality of connecting components of the torque profile device and the at least one segment end. The plurality of tensioning components forms an additive torque profile when coupled between the torque profile device and the at least one segment end.

An exercise device that effectively targets and engages the abdominal and core muscles. The device includes a backrest, a first graspable pole, a second graspable pole, a height-adjustable headrest, and a rocking base. The rocking base acts as the supporting structure and includes a first rocker, a second rocker, and a bridge. The first rocker and the second rocker are connected to the bridge on either side. The backrest receives a user's back and is adjacently and pivotably mounted to the bridge, opposite the first rocker and the second rocker. The first graspable pole and the second graspable pole are positioned opposite to each other across the backrest. The first graspable pole and the second graspable pole are each laterally and rotatably mounted to the backrest. The height-adjustable headrest is centrally mounted in between the first graspable pole and the second graspable pole to receive the user's head.

A folding exercise chair for resistance training has a collapsible chair frame, a pair of resistance mechanisms, and a padded cross-brace. The collapsible chair frame has a seat and a height-adjustable backing. The height adjustable backing is an assembly that enables a user to modify the height of the collapsible chair frame's backrest. The padded cross-brace is connected offset from the seat and across the collapsible chair frame to support the user's back and add comfort while the user is exercising. Each of the pair of resistance mechanisms is a device used to facilitate resistance training exercises. To that end, each of the pair of resistance mechanisms is positioned on either side of the collapsible chair frame.

A respiratory rehabilitation apparatus includes a housing, an adjustment rod provided in the housing to change a pressure load generated during respiration, a pair of stoppers for selectively adjusting respiration pressure, a pair of pressurization-movement parts configured to be pressurized and moved inwards in a longitudinal direction of the housing by respiration pressure during respiration, a pair of elastic members disposed between the pressurization-movement parts and the stoppers, and a pair of diaphragms disposed so as to be in close contact with outer sides in a longitudinal direction of the pressurization-movement parts.

A portable exercise device includes a first body and a second body. The exercise device also includes a support structure pivotably connecting the first and second bodies. The support structure is configured to move between an engaged position and a disengaged position. The device also includes a resistance mechanism configured to resist movement of the first and second bodies toward one another when the support structure is in the engaged position. When the support structure is in the engaged position, the first body is positioned substantially parallel to the second body such that in a first open, in-use configuration of the device, the first body has a first neutral position relative to a pivot axis and in a second open, in-use configuration of the device, the second body has a second neutral position relative to the pivot axis.
