An exercise device includes spaced-apart exercise members engageable by appendages of an exerciser and moveable in opposed directions, a body support member for supporting an exerciser and a platform below the body support member. A synchronizing drive system connects the exercise members with the body support member for moving the body support member in opposite directions relative to the platform by movement of the exercise members in opposite directions, respectively.

An exercise machine for leg strengthening, the exercise machine comprising a stationary frame; and a thigh support member and an ankle support member coupled to the frame and configured to support a user's thigh and ankle, respectively, during a hamstring curl exercise motion. The thigh support member and the ankle support member are each movable with respect to the stationary frame during the hamstring curl exercise motion, thus facilitating contraction and extension of both of a hamstring and glute of the user during the hamstring curl exercise motion.

A weight arm assembly for use with a weight lifting rack is provided, the weight arm assembly including a mounting bracket configured to be attached to a vertical surface in a fixed position, an arm mount configured to be coupled to the mounting bracket so as to be pivotable about a first axis, a stop member coupled to the arm mount and configured to move between an engaged position to prevent pivoting of the arm mount through interaction with the mounting bracket, and a disengaged position to allow pivoting of the arm mount, and a weight arm configured to be coupled to the arm mount, proximate a first end of the weight arm, so as to be pivotable about a second axis substantially orthogonal to the first axis.

A pilates exercise system includes a pair of forward vertical members and a pair of rear vertical members extending upward from a base; a frame positioned at a top of the vertical members, the frame having one or more poles pivotally engaged with one or more framing members; the one or more poles to pivot from a horizontal to a vertical position; a platform assembly slidingly housed within the base, the platform assembly is to slide on a first track and a second track, the platform assembly, having a lower section to engage with the first track and the second track; a middle section slidingly engaged with the lower section; and an upper section pivotally attached to the middle section; and attachment elements secured to the vertical members and to provide locations for attachment of exercise equipment.

An exercise machine includes: a resistance element; a user support; a first movement element coupled to the user support, the first movement element comprising: a first column; and a first connecting element comprising a first pivot point such that the user support is able to pivot about a first axis associated with the first connecting element, wherein the first connecting element is movably coupled to the first column such that it is able to move along a first path; and a second movement element coupled to the user support, the second movement element comprising: a second column; and a second connecting element comprising a second pivot point such that the user support is able to pivot about a second axis associated with the second connecting element, wherein the second connecting element is movably coupled to the second column such that it is able to move along a second path.

A biceps curl machine includes: a resistance element; a user support; a first movement element comprising: a first column; and a first connecting element comprising a first pivot point such that the user support is able to pivot about a first axis associated with the first connecting element, wherein the first connecting element is movably coupled to the first column such that the first connecting element is able to move along a first path defined by the first column; and a second movement element comprising: a second column; and a second connecting element comprising a second pivot point such that the user support is able to pivot about a second axis associated with the second connecting element, wherein the second connecting element is movably coupled to the second column such that the second connecting element is able to move along a second path defined by the second column.

A multifunctional exercise device is described. The multifunctional exercise device has multiple configurations where the user can perform different exercises by simply adjusting the angle of the bench to utilize both the user's bodyweight and gravity as the resistance.

Various embodiments are directed to systems and methods for evaluating jaw movement characteristics of a user, for example, in a plurality of distinct jaw motion directions. In an example implementation, a jaw exercise system as discussed herein is configured to facilitate the exercise and/or quantification of a user's jaw strength in at least one of six distinct directions. As described herein, the jaw exercise system may comprise a frame assembly to which a user may selectively attach one of a plurality of an interchangeable functional assemblies, each configured to facilitate the evaluation of the jaw movement characteristics of a user in six jaw movement directions. The jaw exercise system comprises one or more of a progressive resistance attachment assembly, a passive motion attachment assembly, a force characterization attachment assembly, and a hyoid motion attachment assembly.

An angle-adjustable and swingable Smith machine includes: a frame part for forming an exercise space; a swing part which is disposed in the exercise space and is connected to the frame part; a guide part which is integrally coupled to the swing part and performs a swing operation together with the swing part; a rail part, which is installed on the upper end of the frame part, for guiding the movement of the swing part, and setting or fixing the angle of the swing part; an angle adjustment part for adjusting the angle of the swing part by interworking with the rail part; and a barbell part which is coupled to the guide part so as to ascend and descend.

A weight training equipment with an ultrasonic sensor assembly including a transmitter unit, a receiver unit, a case and the support. The case is rotatably supported upon the support to expose the transmitter and the receiver upwardly. A freely rotatable pin unit is selectively inserted into the hole of the corresponding weight block of the weight training equipment to have its reflection surface downwardly face the sensor assembly. A distance between the pin unit and the sensor assembly during exercise can be measure by ultrasound transmitted from the transmitter unit toward the pin unit and further reflected by the reflection surface and received by the receiver unit.
