An exercise machine with a two directional pivoting user support assembly has a user support or platform which supports the user and pivots about a first pivot axis during an exercise movement, and is also pivotable about at least one second pivot axis to involve the user's core muscles in balancing and maintaining the user support in a stable position. A manually operable locking device with a simple flip switch lever is provided for selectively locking the user support against rotation about the second pivot axis, so that the user can easily chose whether to perform the exercise with a stable support or to add a level of difficulty by using the unstable seat mode and exercising core muscles during the exercise.

A lumbar decompression device may include one or more bases that support one or more uprights with a plurality of upper support members and a plurality of lower support members. The upper support members are configured to engage with a user's upper body and support a user's body weight. The one or more uprights are positioned laterally from the upper support members such that the user may perform a variety of movements of their lower body without contacting the one or more uprights.

Proposed is spinal orthopedic exercise equipment which can obtain an improved exercise effect related to spinal orthopedics with a simple structure. The spinal orthopedic exercise equipment supporting a user's back and waist to apply pressure thereto includes: a first body having a plurality of first protrusions protruding therefrom, a second body coupled to the first body and having a plurality of second protrusions protruding therefrom, a flexible connector located between the first body and the second body to be bendably coupled thereto, and a removable rolling bar coupled to a bottom surface of the first body or the second body having no protrusion and supporting the first body or the second body, the removable rolling bar causing the first body or the second body to perform a seesaw movement relative to a support point thereof.

An abdominal exercise device includes a frame comprising top, middle, and bottom frame sections. The middle frame section has a curved shape for creating a teeter-totter movement during exercise. The device includes a headrest connected to the bottom frame section, a plurality of connectors for connecting elastic bands to the frame, and an elastic band connected to at least two connectors. The two ends of the elastic band are connected to two straps. The device creates the teeter-totter movement to exercise the abdominal muscles in response to a person lying down in supine position with the back of the head on the headrest and the feet in the two straps, the person applying a downward pressure with the feet to the straps to move the headrest from a resting position, and the person removing the downward pressure to allow the headrest to go back to the resting position.

An adjustable ab wheel has a main shaft and two wheels mounted on the main shaft. The main shaft has two external threaded sections. Each one of the two external threaded sections has a thread direction opposite to the thread direction of the other one of the two external threaded sections. Each one of the two wheels has a threaded hole axially defined through the wheel and mounted with a respective one of the two external threaded sections. When a user rolls the two wheels forward, the two wheels approach each other and abut against each other. Abutment between the two wheels allows the two wheels to brake themselves, so that the adjustable ab wheel can prevent users from over rolling the two wheels forward and suddenly falling down to the floor.

Hand-held, portable exercise device which enables the user to strengthen muscles and joints by performing various exercises, the device having a base structure defining a receptacle and supporting at least three omnidirectional rotational elements. A grip element, which may be spherical, has a lower surface positionable on the receptacle and has an upper gripping surface that is convex in at least two dimensions. A hand retaining strap is positionable over the gripping surface of the grip element such that a hand of a human user, the hand having a palm surface and a back surface, can be inserted between the retaining strap and the gripping surface, the palm surface of the user's hand contacting the gripping surface while the retaining strap contacts the back surface of the user's hand to secure the exercise device to the hand.

The present invention is an exercise device comprising a substantially spherical member having a substantially flat portion, wherein a cavity is accessible from the substantially flat portion through a recess, wherein a lip is formed between the recess and the cavity.

A plank support exercise apparatus and related methods is provided. The plank support exercise apparatus has a frame and at least one arm support pad connected to the frame. A ground-interface surface is positioned along at least a portion of the apparatus.

An exercise machine for assisting in the performance of a core exercise that is adjustable between a plurality of configurations. The exercise machine includes a front track, a rear track, a first bar operably engaged with the front track and the rear track, a second bar operably engaged with the front track and the rear track, a first handle member operably engaged with the first bar proximate, a second handle member operably engaged with the second bar, a first foot block operably engaged with the first bar, and a second foot block operably engaged with the second bar. The first bar, the second bar, the first handle member, the second handle member, the first foot block, and the second foot block are all selectively adjustable to accommodate users of different shapes and heights as well as variations of core exercises.
