An exercise machine and a dual resistance structure combining wind resistance and magnetic resistance are disclosed. The dual resistance structure combining wind resistance and magnetic resistance includes a rotating shaft, a wind resistance unit, and a magnetic resistance unit. The wind resistance unit is disposed on the rotating shaft, and includes blades arranged annularly. Each blade has a notch recessed in an axial direction of the rotating shaft. The magnetic resistance unit includes a magnetic resistance member and a magnetic resistance wheel. The magnetic resistance wheel is disposed on the rotating shaft. The notch of each blade faces the magnetic resistance wheel to form a moving space between the magnetic resistance wheel and the notch. When the magnetic resistance member is moved relative to the magnetic resistance wheel along a radial direction of the magnetic resistance wheel, part of the magnetic resistance member is movable in the moving space.

An exercise machine which is capable of having its lift, roll, or pitch adjusted with respect to a base so as to provide a plurality of positions of the exercise machine with respect to the base. The exercise machine generally includes a base and an exercise machine movably connected to the base. The exercise machine may include a track, a carriage slidably connected to the track, and a biasing member attached to the carriage to apply a resistive force to the carriage. A plurality of actuators may be connected between the base and the exercise machine. The plurality of actuators may be utilized to adjust a pitch angle or a roll angle of the exercise machine with respect to the base. The plurality of actuators may also be utilized to lift or lower the exercise machine at a constant angle of pitch and/or roll inclination.

This invention is embodied by a controlled, variable tension line, payout reel machine. A system of sensors detect line tension and line distance paid out, location, and transmit through wired and unwired communication to a microprocessor. The microprocessor is co-located with the reel structure, which in turn applies, via a brake feature, resistance to the reel which is paying out the line being pulled by the user. This invention pertains to all applications where it is desirable to control the tension in a line paid out from a reel or reel. As stated, the payout motive force is supplied by the person, animal or apparatus attached to the end of the line, opposite the reel. The invention applies to the field of precise and measured control of line tension for sport, sport training, performance testing.

A rowing exercise device comprises a support structure; a movable user support movably associated with the support structure for movement relative to the support structure; a movable foot support movably associated with the support structure for movement relative to the support structure; a handle; and a rowing assembly operatively associated with the handle and at least the movable foot support to cause at least the movable foot support to move relative to the support structure with movement of the handle so that both a user s body and one or both feet move relative to the support structure with movement of the handle.

An exercise machine is provided which is configured to place a user in an exercise position, wherein movement during exercise against a load will target the gluteus maximus muscles. The exercise machine positions the body of a user in a lowered or exercise position which supports the user while raising their body to an elevated position, in a manner to stabilize the user and direct movement of the user along the sagittal plane during use, while concurrently isolating the gluteus maximus muscles as the muscles overcoming the load.

A device to aid a swimmer in training includes a piece of swimwear and a plurality of flow resistance increasing structures attached to the swimwear. The flow resistance increasing structures include a fill material constructed with a polymerized, monofilament material. The polymerized, monofilament material can include tulle.

A stationary exercise device includes a support structure and one or more input members such as pedals, handles, or other feature movably connected to the support structure. A movable output member such as a wheel is movably mounted to the support structure, and operably connected to the one or more input members such that movement of the one or more input members causes the output member to move. A resistance member interacts with the output member when the output member is moving to generate a variable resistance force tending to prevent movement of the output member. The variable resistance force may at least partially simulate the effects of inertia and/or momentum.

An exercise machine adjustable resistance system and method for efficiently varying the workout resistance for an exercise machine. The exercise machine generally includes a carriage movably positioned with respect to the at least one rail, a plurality of springs selectively connectable to the carriage to provide a resistance level to the carriage, a plurality of electrically actuated mechanical devices adapted to latch a corresponding one of the plurality of springs to the carriage when in the latch state and unlatch a corresponding one of the plurality of springs to the carriage when in the unlatch state and a control unit in communication with the plurality of electrically actuated mechanical devices to selectively control the state of each of the plurality of electrically actuated mechanical devices to be within the latch state or the unlatch state.
