An exercise machine using motion sensor to track exercise, comprising: an exercise equipment, including a mainframe, the mainframe is fixed and won't be moved by user's movement, an operating mechanism, the operating mechanism is arranged on the mainframe and it will follow the movement of the user; wherein the operating mechanism having a motion sensor, inside the motion sensor having a multiple-axis tracking sensor module and a first microprocessor for detecting the height displacement of the operating mechanism and transmitting the height displacement signal to an electronic control device, then processing by a second microprocessor arranged inside the electronic control device to know whether the motion track of the user reach the preset position during exercise to ensure the effect of exercising.

A neck exercise apparatus includes a neck lever pivotably attached to a channel member. The neck lever has a head portion in front of the channel member. The neck lever is selectively movable along the channel member and the neck lever pivots about a pivot point that is located behind the channel member. The neck lever includes a weight attachment element configured to receive incremental additions of weight.

According to one example, an exercise system includes a vertical housing, a first weighted touchpoint coupled to the vertical housing and configured to allow a user to exercise one or more muscles on a first side of the user, a first weight system coupled to the first weighted touchpoint, a second weighted touchpoint coupled to the vertical housing and configured to allow the user to exercise one or more muscles on a second side of the user, and a second weight system coupled to the second weighted touchpoint. The exercise system further includes a control system configured to cause the first weight system to automatically provide a first heavier weight to the first weighted touchpoint for a first exercise and further cause the second weight system to automatically provide a second lighter weight to the second weighted touchpoint for the first exercise.

A locking and release mechanism for simultaneously positioning an exercise arm in two perpendicular directions, having: (a) a first positioning guide for positioning an exercise arm in a first direction; (b) a second positioning guide for positioning the exercise arm in a second direction; and (c) a locking and release mechanism for locking and releasing the first and second positioning guides, wherein the locking and release mechanism includes: a moveable tab, and one or more positioning pins, wherein movement of the moveable tab locks one two positioning pins into apertures in each of the first and second positioning guides.

A weight system having at least one weight stack moveable in a vertical direction on a lift rod, and a bearing block for housing a linear bearing. The invention further includes a method and apparatus for aligning the linear bearing.

A Vertical Running Machine called a VARRI—Vertical, Anti-Gravity, Re-habilitation, Recovery, and Impact Resistant. It relates to the field of bio-mechanical technology, human physiological facts, and the relationship of gravity and the functionality of the body in motion. This is a Vertical, Anti-gravity device created for Recovery from injuries, physical therapy Rehabilitation with the functional characteristics of Impact-free conditioning and by providing a non-impact system to improve the conditioning or recovery of the user, the patient or the elderly. The device provides a method of a more rapid and safer recovery from injuries and surgery and also is capable to provide enhanced athletic performance by using a vertical, non-impact system which alleviates the damages on the muscles and skeletal structure of the body from the continuous impact of horizontal running on the ground.

The present disclosure relates to a grip apparatus for exercise equipment, the grip apparatus comprising: a first annular member having a first annular sidewall and a first flange extending radially inwardly from the first annular sidewall; a second annular member having a second annular sidewall and a second flange extending radially .[.inwardly.]. .Iadd.outwardly .Iaddend.from the second annular sidewall, a diameter of the second annular sidewall being less than a diameter of the first annular sidewall, the second annular member being positioned within the first annular member whereby the first annular sidewall, the second annular sidewall, the first flange and the second flange define together an annular chamber; a handle member connected to the second annular sidewall; and a bearing in the annular chamber, the first annular sidewall frictionally engaging a first race of the bearing and the second annular sidewall frictionally engaging a second race of the bearing.

A combination exercise assembly for performing aerobic and strength training exercises includes a base, which can be positioned on a substantially horizontal surface. A stationary bicycle is engaged to the base so that a user positioned on a seat of the stationary bicycle faces a first end of the base. A lat pulldown machine engaged to the base proximate to a second end of the base is positioned for engagement by the user positioned on the seat of the stationary bicycle. The stationary bicycle is pedaled to perform aerobic exercise and the lat pulldown machine resists a pulldown motion to perform strength training exercises.

The invention provides an exercise device used by a person to perform abdominal exercises, where the device comprises a weighted ball designed such that the user U can “single-hand drive” the ball through both the concentric portion and eccentric portion of the exercise movement without experiencing unwanted twisting motion of the ball while it is being held during performance of the abdominal exercises. A tether assembly includes a first tether segment and a second tether segment, both being affixed to an outer surface of the ball by a top connector assembly and a bottom connector assembly to define a first and second gaps. The top and bottom connectors reside along a connector axis that extends through the center of the ball. A first coupler extends from the first tether segment for operable connection to a resistance assembly. A second coupler extends from the second tether segment for operable connection to the resistance assembly. The first and second couplers are in an opposed positional relationship and are oriented 90 degrees from each of the top connector assembly and the bottom connector assembly.
