A glute press exercise machine including: a four-bar linkage connected to a stationary frame; a rotatable back support connected to the four-bar linkage; a seat connected to the four-bar linkage; and a foot support connected to the stationary frame. A lower portion of the back support extends below the user's hips to support the users hips during a glute press exercise. This lower portion supports at least 10% of the user's weight. In operation, the seat rotates downwardly away from the user's hips during a glute press exercise and then rotates upwardly again to contact the user's bottom between every repetition of the glute press exercise. The four-bar linkage is pivotally connected to the stationary frame at a location near ground level. The foot support is positioned below 25 cm from the ground and extends forwardly beyond the front of the stationary frame.

A mechanical system for adhering various types of exercise equipment to a smooth floor surface, the system having lockable suction cups that are attached to a first planar portion of the exercise equipment to adhere the exercise equipment to the smooth floor surface when the exercise equipment is in an operational position. Additional lockable suction cups can be attached to a second planar portion of the exercise equipment to adhere the exercise equipment to the smooth floor surface when the exercise equipment is in a storage position. The lockable suction cups support at least a portion of the exercise equipment in the operational or storage positions.

A core training apparatus for the golf swing. A semicircular member is coupled with a support member, and a resistance member is connected to one of the coupling points. The resistance member is secured to a fixed point, and the user rotates the apparatus back and forth with the user standing at the center rotational axis of the semicircular member, with the resistance member being guided along the semicircular member. The back-and-forth rotation acts to increase and decrease tension on the resistance member thereby exercising the core of the user.

A method is provided for fabricating a unitary element, such as an exercise weight, including a composite material. The method includes providing a plurality of solid fragments including at least one non-thermoplastic material. The method further includes providing a plurality of solid particles including at least one thermoplastic polymer and/or elastomer material, at least 75% of the solid fragments having sizes in a fragment size range from zero to 32 millimeters and at least 75% of the solid particles having sizes in a article size range from zero to 1.5 millimeters. The method further includes forming a mixture of the plurality of solid fragments and the plurality of solid particles, the mixture including 90% to 20% of the fragments by volume and 10% to 80% of the particles by volume. The method further includes molding or extruding the mixture into a unitary element through the application of heat and/or pressure.

An exercise system includes a base structure including a first cross brace including first cross brace mounting plates disposed at each end of the first cross brace. A pair of base guide rail supports is secured to and extended substantially orthogonal from the first cross brace and includes a pair of base guide rail receivers. A pair of base pulley supports is secured to and extended substantially orthogonal from the first cross brace and further includes a pulley-support pulley housing. A pair of pulley-support pulleys is rotatably secured to the pulley-support pulley housing. A second cross brace includes a central portion substantially parallel to the first cross brace. The central portion is secured to the pair of base guide rail supports and the pair of base pulley supports. Two end portions are disposed at an angle to the central portion and terminate at second cross brace mounting plates disposed at each end of the two end portions and two central-portion pulley housings. A central-portion pulley is rotatably secured to each of the two central-portion pulley housings.

A pulley force detection device for a weight-training fitness equipment includes a measured element arranged on a stator portion of a pulley of the fitness equipment, and a detection module arranged on a rotor portion. The detection module includes at least one measuring element corresponding to the measured element to detect a motion stroke, a speed, and a power value during force application to a pulley body. Alternatively, the measured element is arrangeable on the rotor portion of the pulley, while the measuring element is arranged on the stator portion of the pulley. The pulley force detection device is further combinable with a weight measurement device for detecting a weight of the weight block.

A resistance training machine comprises a carriage with a handle coupled to move along a linear guide such as a post. First and second end portions of a flexible element are respectively coupled the carriage. A portion of the flexible element forms a loop defined by a series of guiding elements such as pulleys. The loop is coupled to a resistance element such as a weight. First and second fasteners are respectively provided in the first and second end portions of the flexible element. A user can adjust the carriage to a starting position at their desired height and affix one of the fasteners to an anchor point of the receivers. The user can move the carriage either through causing the loop of the flexible element to be reduced in length and to pull on the resistance element or plates on plate horns to perform resistance training.

A housing for a Time-of-Flight (ToF) range meter includes a wall structure defining a first optical beam path to an emitter of the ToF range meter, and a second optical beam path to a detector of the ToF range meter, and a transmissive optical diffusor configured to cover the beam path to at least one of said emitter and said detector. The housing may be connected to a ToF range meter into a ToF ranging device. Such a ToF ranging device where the ToF ranging device is directed to measure a distance to a reflector member to determine a distance which correlates to the weight of the selectively engaged weights.

An apparatus includes a rolling mechanism and a pulley device. The rolling mechanism is connected to a cable and configured to traverse the cable from a first end of the cable toward a second end of the cable, the cable being attached to and extending between a pair of support members. The pulley device is removably coupled to the rolling mechanism and attached to a tackling bag, the tackling bag being configured to be tackled when propelled from the one of the pair of support members toward the other of the pair of support members. The pulley device is separated from the cable when the tackling bag is propelled from the one of the pair of support members toward the other of the pair of support members.

An exercise apparatus comprising: a frame; first and second vertical guides coupled to the frame; first and second carriages carried on the respective first and second vertical guides, each of the first and second carriages having an upper carriage portion, a lower carriage portion and a carriage locking mechanism operable to lock and release the lower carriage portion to a selected vertical position along the first and second vertical guides; and an exercise bar coupled to the upper carriage portion of the first and second carriages, the exercise bar operable to translate or rotate to actuate the carriage locking mechanism.
