An air-cleaning fitness device has a main frame, a housing, a driving assembly, a fan device and at least one filter. The housing, the driving assembly and the fan device are mounted on the main frame. The housing has a confined space and an airflow passage. The driving assembly and the fan device are located inside the housing and connect to each other. The fan device has a second inlet and a second outlet. The second inlet and the second outlet are respectively aligned with two ends of the airflow passage. The at least one filter is mounted on the housing and is capable of covering either end of the airflow passage. The driving assembly has at least one driving member which extends out of the housing and drives the fan device. When the user operates the air-cleaning fitness device, the air-cleaning fitness device purifies the air at the same time.

A control device for an electrical stimulation apparatus in the present disclosure includes a control section that adjusts an output of an electrode. The electrode gives electrical stimulation to a predetermined part of a body doing a pedaling exercise. The predetermined part is at least one of a leg and an arm. The control section adjusts the output of the electrode in such a way that the electrical stimulation is given to the predetermined part in relation to an exercise unit of the pedaling exercise. Furthermore, the control section adjusts strength of the electrical stimulation related to the exercise unit, in accordance with an amount of a physical activity of the body during the pedaling exercise. In this way, electrical stimulation can be given to a predetermined part in a variable manner during the pedaling exercise.

An exercise equipment with an improved connecting bar connecting an exercise foot retaining device to a resistance, wherein a first longitudinal pedal bar is connected to a first bent longitudinal pedal connector bar and a second longitudinal pedal bar is connected to a second bent longitudinal pedal connector bar, the first and second bent longitudinal pedal connector bars each having a bent angle greater than zero and less than ninety degrees to thereby prevent an occurrence of a dead angle.

A physical exercise apparatus and method of using the same targets the balanced development of a user's deltoid, pectoralis or upper pectoralis muscles by providing for a user to perform a target, upper body, weight lifting exercise with a resistance load, such as with a barbell, while the user simultaneously performs a distraction exercise of cycling with the legs. The distraction exercise inhibits the muscles of the lower body from assisting the upper body with the target exercise. The apparatus includes a seat or bench for a user to perform the weight lifting and cycling in one of a seated position, a supine position, and a partially supine position. The apparatus also includes a single or multi-level support for holding the resistance load adjacent the seat or bench, and movable foot pedals that are adjustable to a selected location in a two-dimensional plane at which the user performs cycling.

An exercising apparatus for exercising at least one limb, having a supporting frame and at least one crank which is arranged on a rotation shaft assigned to the supporting frame, and having at least one limb support which can be fastened to the at least one crank at different radial distances from the rotation shaft. A detector is provided for detecting the radial distance of the at least one limb support from the rotation shaft. The invention further relates to a limb support and to a method for determining the force acting on a limb support of an exercising apparatus.

An exercise device with advanced bench-cycling exercises for glute, abs and leg toning, for use in both the stomach down and up positions, has: a bottom support and at least one main support stem extending upwardly; a main joint body support frame rotatably connected to the support stem to allow lower support and upper support bars to be tiltable. The upper support bar is sufficient to support at least a portion of a human torso, and is rotatably connected to the main joint; one or two lower support bars adjustable in length, and having a top portion connected to the main joint, upper support bar or the at least one support stem; and a bottom portion extended away from the main joint; two cranks located on the bottom portion of the lower support bar; and a pair of pedals separately connected to their cranks, the cranks being adjustable in length.

An exercise chair allows a user to perform a lower extremity exercise in a sitting position. The exercise chair includes: a seating portion configured to allow the user to sit on; a backrest configured to support the back of the user; and a support mechanism configured to support the backrest. The support mechanism is configured to support the backrest so as to allow the backrest to reciprocate to right and left and to rotate in roll.

The invention discloses an elasticity adjusting mechanism of an exercise equipment which includes a base, a staggered frame, an adjusting socket, an elastic body and force exerting member. The base and the staggered frame pivot with each other and constitute the main structure of the elasticity adjusting mechanism of the exercise equipment. The staggered frame extends outwardly from the base and includes an extended socket and a plurality of fixed portions, the fixed portions are disposed on the staggered frame and with different distances to the extended socket. When the adjusting socket is selectively assembled with one of the fixed portions at different positions, the elastic body passing through the extended socket and the adjusting socket changes its elasticity in accordance with extension amount.
