An exercise device is disclosed including a first elongated structural member extending in a longitudinal direction. A resistance element is connected to the first elongated structural member, the resistance element providing a resistance force. A seat is connected to the first structural member, the seat includes a seating surface. A drive which drives the resistance element includes a handle to be held by a user. The seat and resistance element are moveable with respect to each other in a direction parallel to the longitudinal direction and a centroid of the resistance element is arranged lower than an upper edge of the first elongated structural member.

An illumination device for directing light into a transparent fluid tank of a fluid-resistance exercise machine is disclosed. The device can be coupled with an exterior surface of the tank and includes a light source oriented to project light through a surface and into a region of the fluid tank where the light can be observed by a user of the machine during operation, especially when a rotary device disturbs the fluid to generate the fluid resistance effect. The illumination device can include a control unit having a processor and a communication device, where the communication device receives an exercise-related parameter related during operation of the exercise machine. In response the control unit can dynamically adjust a quality of the light as a function of the received parameter, such as heartrate, output, resistance, time, distance, or speed.

An aquatic exercise device is disclosed, able to exert omnidirectional uniform water resistance while exercising, so that equal force is required to move it in any direction. The water resistance of the device according to the invention can be adjusted in a quick and measured way. This device can be operated with one hand and can be brought close to the body of exerciser.

A resistance system for a rowing machine has a mounting bracket, and a housing assembly, a driving assembly and a restoring assembly mounted on the mounting bracket. The housing assembly is for storing liquid and a paddle wheel. The driving assembly is connected to the paddle wheel and drives the paddle wheel to rotate in a direction only. The restoring assembly is connected to a strip hub of the driving assembly and is able to drive the strip hub to rotate in a reverse direction. The resistance system for the rowing machine has simplified structure. Therefore, it is easy to assemble to resistance system, and manufacturing cost of the resistance system can be decreased. In addition, a service life of the resistance system as well as the rowing machine can be increased.

An aquatic exercise system includes a pool and an aquatic exercise apparatus positioned in the pool. The aquatic exercise apparatus includes a base and an aquatic exercise pole having a first substantially straight section, a second substantially straight section, and a curved transition section between the first substantially straight section and the second substantially straight section. The curved transition section includes a bend, and the aquatic exercise apparatus is positioned in the pool such that bend is above a surface of water in the pool.

An underwater training apparatus is disclosed. The underwater training apparatus may include a barrel. The barrel may contain a plurality of holes disposed across the barrel. Each of the holes of the barrel may pass through a wall of the barrel. The underwater training apparatus may also include a base funnel. The base funnel may contain a plurality of holes disposed across the base funnel. Each of the holes of the base funnel may pass through a wall of the base funnel. The underwater training apparatus may also include a handle. The handle may mechanically couple the barrel and the base funnel.

A magnetic control water resistance rowing machine has a main rack, a ribbon, a ribbon recycling plate set, an aluminum wheel water resistance device set, a magnetic plate set and a seat cushion. The ribbon is connected with a ribbon recycling plate. The ribbon recycling plate set is mounted on the main rack by a torsion spring to recycle the ribbon when the ribbon is loosened; the aluminum wheel water resistance device set is mounted on the main rack and the aluminum wheel water resistance device set cooperates with the ribbon recycling plate set. The ribbon recycling plate set is connected to the aluminum wheel water resistance set drive; the magnetic plate is mounted on the main rack. The magnetic plate cooperates with the aluminum wheel water resistance. The main rack has a slide rail engagement and the seat cushion is slidably engaged with the slide rail engagement.

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.

A semi-submersed floating striking exercise device with a striking portion to be filled with water, a floatation portion at least partially above the striking portion, the floatation portion to be filled with air and an above-the-water portion to be filled with air, the above-the-water portion positioned above the floatation portion. The striking exercise device also includes at least one of a handle and/or an attachment device, at least one air inlet for inflating the floatation portion and the above-the-water portion, and a water inlet for filling the striking portion with water. The striking exercise device optionally includes a tether with a first end and a second end, and a tether harness to be worn on a user, wherein the first end of the tether is attachable to the semi-submersed floating striking exercise device and the second end of the tether is attachable to the tether harness.
