Abstract: A resistance adjustment device of an exercise apparatus include a metal disc that can be driven by movement of a user, a bracket that can be controlled by the user and at least one magnet disposed on the bracket. The magnet can be movable along an adjustment path to approach or move away from a rotation axis of the metal disc so as to increase or decrease a projection area of the magnet on the metal disc for adjusting rotational resistance of the metal disc. The magnet has an irregular quadrilateral cross section gradually widening from a front side closer to the rotation axis to a rear side farther away from the rotation axis, so that during the period of the magnet moving along the adjustment path to approach the rotation axis at a constant speed, the increase rate of the projection area will be gradually accelerated.

Abstract: The present invention relates to a method of detecting a lubrication status between a deck and a belt of a treadmill. The method includes: starting a lubrication detecting procedure of the treadmill by a user, making the belt driving system drive the belt to run for a period of time without the user on the belt of the treadmill, having the user walk on the belt of the treadmill for a period of time at a level state, having the user walk on the belt of the treadmill for a period of time at a predetermined angle. Thereafter, a central control unit of the treadmill calculates a friction coefficient between the belt and the deck of the treadmill according to measuring results of the procedures, and generating a suggestion of maintenance according to a level of the friction coefficient.

Abstract: A training machine provides two independently operable resistance systems for providing resistance to the upper and lower body of a user and to enable training equivalent to circuit training in a small amount of time. A first resistance system provides training resistance to the upper body and comprises a first resistance member with handles coupled thereto. A second resistance system provides a second training resistance to the lower body, and comprises a seat support and a seat, the seat having a first position with a first potential energy and a second position having a second potential energy, the differential providing the second training resistance. Handles are each independently coupled to the first resistance member by a cable fed through a pulley to a cable reel assembly so as to enable the user to operate the handles separately from each other and in any direction.

Abstract: A stationary exercise device having variable footpaths is disclosed. The exercise device includes a frame, a pair of supporting members that have a first end to rotate about an axis and a second end to move along a reciprocating path, a pair of pedals joined to the supporting members, and a guider assembly for adjusting an incline angle of the reciprocating path.
