An exercise device for use when a person is in a pool or other water body. A central boom extends from attachment to a sidewalk around the pool, and extends to a wishbone member that forms a furcated member mounted to the central boom. The wishbone has lateral members that are parallel and spaced with hand-grippable handles at the ends farthest from the central boom, and disposed over the water. A user can grasp the handles and perform numerous exercise movements while buoyed, at least partially, by the water. A lower support member is mounted to the central boom beneath the wishbone, and a handle is mounted to the central boom between the wishbone and the lower support member. The user can rest his shoulders on the lower support member and hold the handle mounted to the boom, and perform abdominal exercises. Many other movements are possible.

Training devices, methods of using training devices and systems involving training devices are described. Training devices may include an attachment unit which includes a swivel, a plurality of support members, a first member and a second member. A training device may be configured to a first device, the first device may be moved with the training device configured to it in a desired motion and in as many repetitions as desired, and the training device may be removed from the first device. Training devices may be used in conjunction with hand units, strap units and other devices and/or appendages.

A jaw-strengthening device has a first receiver configured to receive a row of teeth having first and second molar sections, the first receiver having a first air chamber within the receiver positioned in a first molar section, a second air chamber within the receiver positioned in a second molar section, and an egress valve, configured to permit egress of air and prevent ingress of air, in communication with the first and second air chambers, a second receiver configured to receive a second row of teeth, the second receiver having a third air chamber within the receiver positioned in a first molar section, a fourth air chamber within the receiver positioned in a second molar section, and an ingress valve in communication with the third and fourth air chambers, wherein the first and third air chambers, and separately the second and fourth air chambers, are in communication.

A series of improved exercise machines with a movable user engagement member operatively linked to a sliding while rotating user support such that when the user engagement member is engaged and activated by the user the user engagement member concurrently causes movement of the operative linkage system, which concurrently causes the user support to slide while rotating. This creates dynamic motion of the user support relative to the user engagement member.

The invention relates to medical technology, to non-medicinal means for improving physical health and enhancing physical capabilities by means of a breathing system, and specifically relates to devices which are intended for inhaling hypoxic/hypercapnic mixtures having various compositions, and which have an adjustable resistance to inhalation/exhalation. According to a first variant, a breathing exerciser contains a first chamber, which is connected to means for connecting the exerciser to a user's respiratory tract; a second chamber, communicating with the first chamber; a third chamber, communicating with the second chamber; means for adjusting the composition of a breathing mixture; and means for adjusting the resistance to inhalation/exhalation, installed in a channel through which the first chamber and the second chamber communicate. The second chamber communicates with the atmosphere; the third chamber is elastic; means for regulating the composition of a breathing mixture are in the form of adjustable throttling devices installed in the channels through which the second chamber communicates with the third chamber and with the atmosphere; the means for adjusting the resistance to inhalation/exhalation are capable of separately and independently adjusting resistance to inhalation and resistance to exhalation. A second variant is characterized in that a first chamber communicates with a second chamber by means of two parallel channels, in that means for adjusting the resistance to inhalation/exhalation are installed in the parallel channels, and in that a breathing mixture is capable of passing through said channels in mutually opposite directions.

An exercise apparatus comprising: a weight stack, a flexible elongated cable having a downstream portion that is interconnected to a user selectable number of the one or more individual bodies of weight and to a second resistance device, a manually movable actuating device interconnected to a proximal end of the cable, a downstream portion of the cable being interconnected to the one or more individual bodies of weight and to the second resistance device in an arrangement that pulls on both the one or more individual bodies of weight and the second resistance device.

A stationary exercise equipment has a supporting structure, a movable user interface connected to the supporting structure, and a force-resisting device. The force-resisting device with a hub mounted continuously variable transmission configured therein provides a variable resistance force that varies an amount of force with a movement of the movable user interface. The hub mounted variable transmission is operably to vary the resistance force of the movable user interface in a manner of varying a rotational rate of the user interface to increase or decrease as required.

An exercise machine handle indicia system for facilitating efficient and proper exercise movements by an exerciser. The exercise machine handle indicia system generally includes a frame, a carriage movably positioned upon the frame, a bias member connected between the carriage and the frame that applies a bias force upon the carriage, and a first handle and a second handle connected to the frame near the first end of the frame. The first handle includes a first indicia to indicate where to position a first hand of an exerciser to perform a first exercise and the second handle includes a first indicia to indicate where to position a second hand of the exerciser to perform the first exercise. During the performance of an exercise, the exerciser is instructed by a human instructor or an electronic device which indicia on the handles to position their hands or other body parts.

An aquatic exercise device (100) includes a cuff strap (102) for fastening a plurality of fins (106) to a user's leg. The cuff strap (102) is configured to position the plurality of fins (102) to extend outwardly form an interior of the cuff strap (102) when the cuff strap (102) is fastened to an ankle area of the user's leg. The plurality of fins (106) provide resistance in a direction opposite to the direction of motion of the user's foot when the aquatic exercise device (100) is moved through water.
