An exercise device for performing exercises suitable to strengthen thigh and hip muscles such as a leg press machine, a total hip, a stationary bicycle, or a moving bicycle, and more particularly provides an exercise device for strengthening thigh and hip muscles while protecting the knees and ankle joints by enabling a user to locate a lower end of an arm on the user's thighs in a sitting, prone or supine position and move the user's legs in order to minimize a load or stress added to the knee and ankle joints.

An attachment handle for an exercise machine includes a flexible tension member, a first ring secured to a first end of the flexible tension member, a second ring secured to a second end of the flexible tension member, and a hand grip having a bore surrounding the flexible tension member. The hand grip is slideable along the flexible tension member between the first and second rings. The hand grip defines a first shoulder at a first end of the hand grip and a second shoulder at a second end of the hand grip.

A system for a quantitative detection of a movement. The system includes a signal emitter and two signal receivers, positioned in series, along a first axis parallel to a second axis of movement of a reflective marker provided on a moving object. The reflective marker is configured to reflect a signal emitted by the signal emitter towards the two signal receivers. The two receivers have a signal reception coverage such that allows existence of a reflective marker position, on the second axis, in which the reflective marker of a given size is recognized simultaneously by the two signal receivers.

A method for counting spatially arranged, moving markers, wherein the markers being arranged to move along a movement axis parallel to a sensors axis of sensors for detecting the markers during movement. The number of sensors is lower than the number of markers in order to decrease the cost of the sensors system. The present system supports stacks having objects, associated with the markers, of different sizes such as weight plates of increasing height) or different weights.

An adjustable carriage assembly includes a carriage defining a passage configured to receive a frame member therethrough such that the carriage is moveable along the frame member, and a locking structure configured for engaging the frame member to lock the carriage in position relative to the frame member. The locking structure includes a main pin and an auxiliary pin connected to the carriage that are each moveable between a locked position, where the respective pin extends into the passage and is configured to engage the frame member to lock the carriage in position, and an unlocked position, where the respective pin is retracted from the passage and is configured to disengage from the frame member. The carriage may also include a first portion and a second portion, where a space is defined between the first and second portions, and the second portion is adjustable with respect to the first portion.

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.

An improved exercise machine has a stationary longitudinal monorail structure that extends between front and back end stationary exercise platforms, and an exercise platform mounted on a levitated carriage that is reciprocally movable along the monorail between the stationary platforms. Magnetic elements arranged on various opposing surfaces of the carriage and monorail generate magnetic forces that levitate and stabilize the carriage as it moves relative to the monorail thus substantially eliminating contact friction. Springs selectively attachable to the movable platform provide a resistance force for exercising. Pseudo-levitation and eddy brake elements on the carriage and monorail structure further stabilize the carriage and platform.

A modular unit for physical activities, outdoors, containing a multi-purpose structural metal frame mounted on a floor of a trailer on wheels, through a fixing point. The multi-purpose structural frame includes two vertical beams linked by longitudinal and transversal longitudinal rails with sliding guides to associate two structurally extendable modules mounted at the front and rear and in turn two horizontal storage cabinets; it is also arranged in a solid way by bolts for fixing both to the multi-purpose structural frame and to the floor of the trailer to a set of individual pulley unit module and to another set of double pulley unit module associated with a weight system with protective covers, and also includes a vertical storage cabinet integrally associated with the multipurpose structural frame.

A self-spotting exercise apparatus is formed to include a pair of weight-bearing arms that are attached to a back frame assembly of the apparatus by a pair of double-hinge components. The double-hinge configuration provides a full range of motion for the weight-bearing arms with respect to the “fixed” apparatus itself. The opposing end terminations of the weight-bearing arms are configured to support weight plates (which may be changed out, as desired), with the weight-bearing arms also including a pair of handgrips for the user to hold as he/she moves the weight-bearing arms during an exercise routine. Self-spotting is provided by the use of a foot-activated motion bar, which is attached to a pair of vertical support posts that hold the distal ends of the extended arms when not in use.
