A device for an exercise apparatus includes a linear adjustment system and a sensor coupled to the linear adjustment system. The exercise apparatus includes a loading interface and a frame coupled to the loading interface for performing an exercise. The linear adjustment system fixes the loading interface of the exercise apparatus at any one of a plurality of functional positions in a functional range of the loading interface. The sensor measures the force exerted on the linear adjustment system. A correlating mechanism is used to correlate the force exerted on the linear adjustment system with the force exerted on the loading interface. The device allows exercisers to exert high or maximum loads in any one of a plurality of positions throughout their entire range of motion without first passing through a weak range of motion.

A non-motorized treadmill includes a non-motorized treadmill body and a composite resistance module. The non-motorized treadmill body includes two rollers and a treadmill belt. The treadmill belt is wound around the two rollers. The composite resistance module includes a reluctance module and a fan wheel. The reluctance module includes a wheel body and a resistance member. The wheel body is mounted to one of the rollers. The resistance member is located close to the wheel body. One of the wheel body and the resistance member includes a metal member. The other of the wheel body and the resistance member includes a magnetic member. The fan wheel is connected to one side of the wheel body so that one of the rollers is subjected to magnetic resistance and wind resistance when rotated.

Chair for work place environment or for means of transportation that is capable of providing physical training. The subject of the invention is such chair that used for lasting period of times, encourages muscular physical work and can even be utilized during office work hours, or during travel, and as it requires, the daily training can be performed on it. The principal idea of the invention is that certain parts of the chair shift, or signal and the sitting person has to produce muscular force against those actions. Usage of this kind of chair can save the supplemental time one should spend during leisure time, because physical training can be done while sitting on this chair. The chair can be controlled by smart device, or computer, hence a variety of training schemes can be offered for selection.

An exercise machine allows a user to perform a variety of resistance exercises with adjustable resistance levels. The machine is made up of an arm, a user platform, a horizontal base, an adjustable counterweight arrangement, a pull rod, a drive chain system, sprockets, shafts, adjustable fan, a slip bearing, a recoiler, a plurality of wheels, a drive chain system housing, a user back support, a user cable grip, and a circuit-breaking sensitive rubber mat. When the arm is moved upwards (by a user) the pull rod attached to a drive chain initiates the drive chain system rotation. The drive chain system rotation includes an adjustable weight fan that creates resistance to the arm's upper movement through inertia. The adjustable counterweight arrangement determines the arm drop speed and the arrangement has multiple positions. Other variants include a plurality of electronic encoders.

The present invention provides a training device for training a user to use a pressurised metered dose inhaler (PMDI). The device comprises a body, air expulsion means (e.g. bellows) for expelling air along an air flow path and an actuator for actuation of the air expulsion means. The air flow path comprises a restriction such that upon expulsion of air along the air flow path, an audible signal is generated. The audible signal mimics that generated during use of a PMDI.

An exercise apparatus for performing a back extension exercise comprising: a frame, a seat having a seating surface and a pelvic stabilization pad having a lower back engagement surface, an input arm assembly interconnected by a first interconnection to a first resistance mechanism, the input arm assembly including a manually graspable mechanism and being arranged on the apparatus such that the input arm assembly is pivotable beginning from a start motionless position along a path of travel toward the pelvic stabilization pad under resistance exerted by one or both of the resistance mechanisms, wherein the first resistance mechanism is adapted to increase resistance as the degree of pivoting of the input arm assembly increases along the path of travel away from the start motionless position rearwardly toward the pelvic stabilization pad.

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.

Described herein are embodiments of stationary exercise machines having reciprocating foot and/or hand members, such as foot pedals that move in a closed loop path. Some embodiments can include reciprocating foot pedals that cause a user's feet to move along a closed loop path that is substantially inclined, such that the foot motion simulates a climbing motion more than a flat walking or running motion. Some embodiments can further include reciprocating handles that are configured to move in coordination with the foot via a linkage to a crank wheel also coupled to the foot pedals. Variable resistance can be provided via a rotating air-resistance based mechanism, via a magnetism based mechanism, and/or via other mechanisms, one or more of which can be rapidly adjustable while the user is using the machine.

A device including a first flow channel, a second flow channel and a body part including an inner volume. A first space of the inner volume is adapted to be filled with liquid and a second space of the inner volume is arranged to receive steam. The device further includes means for conveying a gas flow from the steam space of the inner volume via the first flow channel to the outside of the device during inhalation and means for conveying the exhaled gas flow from the outside of the device via the second flow channel to the first space of the inner volume. The device further includes means for measuring a flow and a temperature of an airflow, and means for adjusting the flow of the airflow mechanically and/or automatically. The present disclosure further relates to a method and a system.
