A machine for exercising arms and shoulders and reducing abdominal fat. The machine includes a frame of curve shape. Straps extend from the ends of the frame for tightening the machine over the abdomen. The frame includes an upper rail, a middle rail, and a lower rail, the upper rail and middle rail form an upper track and the middle rail and lower rail form a lower track. An upper set of rollers are mounted in the upper track and an upper handle is coupled to the upper set of rollers. A lower set of rollers are mounted to the lower track and a lower handle is coupled to the lower set of rollers. The upper handle and the lower handle are grasped to pull and push the upper set of rollers and the lower set of rollers to roll back-and-forth in the upper track and the lower track respectively.

An exercise machine reversible resistance system for reversing the directional force of resistance against an exercise implement before, during, or after the performance of a routine of one or more exercises. The exercise machine reversible resistance system generally includes a frame, an elongated member movably positioned upon the frame, wherein the elongated member has a first run and a second run, a resistance device that applies a resistance force to the elongated member in a single direction, an exercise implement movably connected to the frame and a clutch connected to the exercise implement. The clutch is adapted to selectively engage the first run or the second run of the elongated member for selective control of the resistance direction of the exercise implement.

An exercise machine for reducing abdominal fat as well as exercising the arms and shoulders. The exercise machine includes a frame that can be of a curved shape to conform to the curves of the abdomen. Straps extend from the ends of the frame for tightening the exercise machine over the abdomen. The frame includes an upper rail, a middle rail, and a lower rail, wherein the three rails run horizontally and parallel to each other along the length of the frame. The upper rail and the middle rail form an upper track and the middle rail and the lower rail forms a lower track. An upper set of rollers are mounted in the upper track and an upper handle is coupled to the upper set of rollers. Similarly, a lower set of rollers can be mounted to the lower track and a lower handle is coupled to the lower set of rollers. The upper handle and the lower handle can be grasped to pull and push the upper set of rollers and the lower set of rollers to roll back-and-forth in the upper track and the lower track respectively.

An exercise machine with adjustable handles that provide for multiple handle positions. The exercise machine with adjustable handles generally includes a frame with one or more rails, a carriage movably positioned upon the rails, and a pair of adjustable handles positioned near an end of the frame. The adjustable handles each have a handle portion that is movably connected to a corresponding handle stanchion to pivot from a storage position to an extended position.

A reversible resistance exercise machine for reversing the direction of applied resistance against a movable platform of an exercising machine. The exercise machine has a frame, a carriage movably positioned upon the frame, and a plurality of biasing members. A plurality of first tension connectors are accessible near the first end of the carriage and are adapted for removably attaching selected biasing members near the first end of the carriage to resist motion of the carriage in the first direction. A plurality of second tension connectors are accessible near the second end of the carriage and are adapted for removably attaching selected biasing members near the second end of the carriage to resist motion of the carriage in the second direction. A user selectable amount of force may be applied to the carriage to resist movement in either of the first direction and the second direction.

An exercise machine. The machine includes a frame with front and rear upper support beams. Guide rails span between the two support beams and are connected thereto. Right and left handles are configured to slide back and forth along the length of the guide rails between the front and rear support beams. During operation of the machine, a user grabs the handles and moves them back and forth in a swinging motion that mimics traversing a set of monkey bars. The guide rails may be arranged in a non-parallel configuration to provide a more natural path for the user's hands during operation and to reduce unwanted stress on the user's shoulders by limiting handle movement along the path to accommodate a more comfortable range of motion.

A linkage mechanism with an elliptical motion trajectory includes a main body having two guiding tracks with a changeable lifting angle, a flywheel assembly and two handles installed on a front side of the main body, a first linkage rod pivotally attached between guiding rods of two driving linkage assemblies and two cranks of the flywheel assembly. The two pedals respectively include a front end pivotally attached onto each one of the cranks. Each one of the pedals moves together each one of the guiding rods and along each one of the guiding tracks and drives the flywheel assembly and each one of the handles to move forward and backward.

An exercise machine is used to train the low back core musculature and lumbopelvic complex. The exercise machine can also be used to provide stability to the lumbar spinal column. The exercise machine includes a stationary bench substantially parallel to the floor and a rotating bench that is capable of rotating at an angle α about an axis, wherein the axis is located between the stationary bench and the rotating bench. A resistance means is used to adjust the amount of force required to move a resistance bar away from the rotating bench, while performing at least one of: a plank, a side plank, a bird-dog, a superman, a lumbar extension, a glute bridge, a single leg raise, a dual-leg raise, a bent leg raise, or a resisted push-up.
