A reciprocating transmission structure of an exercise machine, mounted to a frame of the exercise machine, includes a first reciprocating member, a second reciprocating member, a main rotating wheel, a first link, a second link, and a resistance wheel. The first reciprocating member reciprocally moves with a first reciprocating pivot portion as its axis. The second reciprocating member reciprocally moves with a second reciprocating pivot portion as its axis. The first link and the second link drive the main rotating wheel to rotate with a rotating shaft as its axis. The main rotating wheel drives the resistance wheel to rotate. After the first reciprocating member and the second reciprocating member move reciprocally, the resistance wheel can be driven to rotate by the cooperation of various components. The exercise machine is suitable for performing exercises related to reciprocating movement, and the operation is easier.

An exercise assembly structured to perform different rowing routines characterized different rowing motions. A resistance device is movable within a chamber and is cooperatively structured therewith to resist such movement. A drive assembly includes two drive sections each independently connected in driving relation to said resistance device. A connector structure includes two connector members each attached to a handle and connected in driving relation to a different one of said drive sections. The handle is selectively movable through the plurality of different rowing motions, at least one of which results in the two drive sections concurrently driving the resistance member and being concurrently driven by the two connector members. At least one other rowing motion of the handle is defined by each drive section alternately driving the resistance member and being alternately driven by interconnected ones of said connector members.

A weight sled for fitness training that uses a plurality of separately-adjustable resistance mechanisms to allow for adjustment of overall resistance, bias correction and directional control, and wheel skid or slippage control, by means of differential adjustment of the resistance of the plurality of resistance mechanisms. Differential adjustment of the resistance mechanisms can be used to manually or automatically offset a directional bias in the sled, ground surface, or the athlete's abilities to keep the sled moving in a linear motion, and to prevent wheel skid on surfaces with differing friction coefficients.

An aerodynamic drag component for removably placing on a swung athletic implement may comprise a hollow thin-walled body having an outer profile with a width less than its height and a plurality of spaced-apart perforations with concave lips shaped to scoop air from outside the hollow thin-walled body, through the perforations, and into the hollow thin-walled body to increase aerodynamic drag in a first direction, and convex surfaces opposite the concave lips that are shaped to divert air outside the hollow thin-walled body away from the perforations, to reduce airflow into the hollow thin-walled body to reduce aerodynamic drag in a second direction opposite the first direction, to provide varying aerodynamic drag resistance during a swing. The aerodynamic drag component may freely rotate or freely translate or both on a longitudinally-extending portion of the swung athletic implement. Multiple aerodynamic drag components may be used at once.

An apparatus and method may exercise muscles of a body part, especially the neck, waist, torso, legs, and glutes from any angle with variable resistance while taking up minimal floor space. The apparatus may improve the ability of athletes, including football players and wrestlers, to better prepare for contact from any angle while engaged in their sport. The apparatus may include a ring having a guide track therein. Another inner ring may also be provided in different sizes and shapes to accommodate a variety of users. A car may be connected to a source of resistance ride freely along the guide track. The source of resistance may be other gym equipment including a bungee cord, a cable cross over machine, springs, and the like. As the user freely exercises by moving the body part, the car may adapt to the user's position to facilitate a full range of motion.

A passive-type treadmill is disclosed which includes a closed-loop belt rolling around two spaced apart rollers for providing a running platform, a first and a second handrail parallel to each other and extended upward angling to a surface of the closed-loop belt at larger than 45 degrees, and a towel rack having at least a first and a second clip for stretching a towel between the first and the second handrail.

An exercise machine has a base housing, a boom having an elongate rigid body that extends from a proximal end to a distal end, and a pivot mount which pivotally mounts the proximal end of the boom on the base housing such that the boom is able to pivot with respect to the base housing between a rowing configuration wherein the boom is generally horizontal, and a skiing configuration wherein the boom is generally vertical. A seat element is slidably mounted on the boom, and ski handles attached to a ski cable which extend through ski handle stops at the distal end of the boom. A row handle is also attached to a row cable that extends from the base housing. The exercise machine further includes a resistance device, and a transmission system that connects the ski cable and the row cable to the resistance device.

An improved magnetoresistance adjustment device of fitness equipment suitable for using in a fan-type fitness equipment. The fitness equipment having a traction rope, and including: a resistance wheel mounted on the fitness equipment and having a wheel and an axle, the axle being mounted on the wheel; a magnetoresistive ring mounted on the resistance wheel; a fixing member fixedly mounted on the axle and having a positioning bolt, a direction of the fixing member extending to the magnetoresistive ring being a displacement direction; a displacement member having a displacement hole, a fixing portion and a magnetoresistive portion, the displacement hole allowing the positioning bolt to pass through, and the displacement member repeatedly displacing along the displacement direction to bring the magnetoresistive portion closer to or away from the magnetoresistive ring, and the fixing portion being connected to the traction rope and driven by the traction rope.

A flywheel exerciser having a hybrid resistance system includes: a body having a flywheel unit; a wind resistance system disposed on the flywheel unit; and a magnetic resistance system disposed on the flywheel unit. The wind resistance system is a conventional wind resistance which provides segmental adjustment, the present invention is additionally provided with a magnetic resistance system. When the resistance generated by the wind resistance system is insufficient or excessive, the resistance can be further finely increased or decreased by adjusting the magnetic resistance system to provide the resistance that best meets the user's needs.
