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 machine for concurrently performing pressing motions with the hands and feet, the machine having a base having front and back ends, two or more user supports, at least one lower body user support with an engagement means for the user's feet and at least one upper body user support with an engagement means for the user's hands. The upper body user support and lower body user support move fore and aft on opposing ends of the base frame and at least one of the upper body user supports and at least one of the lower body user supports cooperate with one another to move in opposing fore and aft movement patterns during operation of the machine.

A machine for concurrently performing opposing pushing and pulling motions with the legs and arms at various angles to simulate multiple exercises including climbing, running and crawling motions, wherein the machine is adjustable in angle. The individual lower body user supports move in a back and forth pattern on rails and include foot platforms and shin support pads for support a user's lower body and pivoting upper body user support hand grips wherein the left upper body user support and left lower body user support move in opposite directions and the right upper body user support and right lower body user support move in opposite directions and all four user supports move in unison.

An exercise device comprising an outer tube having a first end and an open second end. An inner tube has a first end fitting inside the open second end of the outer tube. Thus, the inner tube can slide inside the outer tube. Typically, from about 5 percent to about 30 percent of the inner tube will be inside the outer tube when the device is at rest (that is, no force is applied). When the user applies a force to the first end of the outer tube, the inner tube can slide inside the outer tube against force provided by a resistance device. Depending on the force applied, the inner tube can be inserted from about 10 percent to about 100 percent of its length inside the outer tube. The resistance device can be a spring, an elastic cord, magnetic repulsion, or the like.

The present utility model provides a water-magnetic double-resistance rowing machine, wherein a pullback device is in transmission connection with a rotating shaft of a damping water tank and a magnetic control wheel simultaneously, and through the cooperation of the damping water tank and the magnetic control wheel, the rowing machine has double resistance of water and magnetism, which can achieve greater exercise intensity.

An inflatable unweighting enclosure for an exercise device is provided formed from a pair of opposing sheets attached to each other by a seam along a closed shape at their perimeter portions, each of which has a top region, an opposite base region, and central region. A trim path interrupts each articulated shape at the base region that defines a perimeter of a base opening for the enclosure when inflated, in which the base and base opening are substantially planar and the base perimeter defines an enclosure inlet. When inflated, the pair of flexible sheets expand laterally apart to define an enclosure inner space and form an elongate, disc-shaped structure interrupted by the base opening. The base opening attaches to a base support of the exercise device, which is shaped and sized to orient and support the enclosure vertically for providing unweighting to a user attached to a top opening.

An apparatus for an exercise task includes a pneumatic arrangement, which includes a pressure source, a pneumatic controller, pneumatic transfer channels, and at least one pneumatic resistor element, which includes a pneumatic cylinder with its piston. The apparatus additionally includes a mechanical lever arm structure or another mechanical connecting structure, which is for a user's limb contact and which is at a second end connected to the pneumatic resistor element. The apparatus additionally includes a sensor structure, a calculation arrangement and a display. The sensor structure is arranged to measure at least one measurement quantity of the exercise task and, based on the measurement, the calculation arrangement is arranged to form information on the display of the apparatus, regarding the power and/or force and/or range of motion of the exercise task. In the invention, regardless of the number of pneumatic resistor elements, the sensor structure includes one pressure sensor only, and to compensate for the small number of sensors, the calculation arrangement includes a correlation-taught calculation unit, which comprises a correlation algorithm taught with a larger number of sensors than the number of sensors in the apparatus, concerning the correlation between power and/or force and/or range of motion of the exercise task and the measured information.

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 exercise machine has a main frame and a user support movably mounted relative to the main frame for movement between a start position and an end position during an exercise. At least one user engagement device is movably mounted relative to the main frame for engagement and actuation by a user during an exercise, and a connecting linkage translates movement of the user engagement device to movement of the user support. A lifting arm is movably mounted relative to the main frame and associated with at least one of the user support, user engagement device, and connecting linkage so as to move during an exercise. A load associated with the lifting arm provides exercise resistance.
