Abstract: A weight training machine generally includes a supportive frame, a first mechanism, and a second mechanism. The first mechanism includes a first weight stack, a first cable system, and a second cable system. The second mechanism includes a second weight stack, a third cable system, and a fourth cable system. In each of the first and second mechanisms, one end of a cable can be easily attached to a moving pulley block to have the moving pulley block converted to a fixed pulley block. As a result, the force applied to a handle for lifting the associated weight stack becomes double as compared to the cable being not attached to the moving pulley block.

Abstract: A composite motion exercise machine includes a control panel which provides a plurality of movement modes and allows a user to issue a command to change the configuration of linkage units of the exercise machine to have the machine perform a movement mode without manual adjustment, so that the pedal of each linkage unit can be moved along a closed trajectory. The control panel also allows the user to finely adjust the trajectory and the resistance associated therewith. The trajectory performed by each pedal of the exercise machine is ergonomic so that the user can be protected from exercise injury.

Abstract: A hand-foot composite motion exercise machine generally includes a supportive frame, a transmission unit, a crank means, and a pair of linkage units. The exercise machine allows a user to change the configuration of each linkage unit through a raising/lowering device and a displacing device, so as to adjust the motion path of a pedal provided at each linkage unit, and the force required for treading the pedal. In use, while a user steps on the pedals to exercise, each pedal can perform a substantially elliptical closed path, which is ergonomical so that the user can be protected from exercise injury.

Abstract: A joint structure of an endless treadmill belt of a treadmill is provided. The treadmill belt is a sandwich-type laminated rectangular treadmill belt. Two ends of the treadmill belt are cut to form serrations. Two ends of a bottom layer of the treadmill belt are meshed with each other. At least one plastic piece is placed on the joint of the two ends of the bottom layer. The serrations of two ends of a top layer of the treadmill belt are connected with each other in a cross-knitted manner, and the pointed portions of the serrations of the two ends of the top layer are inserted into and covered by the plastic piece and then the two ends of the treadmill belt are joined together by hot melting to form an integral flat joint of the treadmill belt.

Abstract: An exercise treadmill includes a machine body, which has at least two rollers, a flywheel linked with one of the two rollers, a support assembly mounted between the two rollers, and a running belt fitted around and engaged with the two rollers and arranged around the support assembly. The exercise treadmill is provided with an accelerating means so that, while a user is walking or running on the machine body, the treading force provided by the user allows the running belt to be accelerated to move around the two rollers for generating electrical power. In addition to improving body heath, the electrical power produced by the treadmill in the training activity can reduce the electrical consumption of city power.
