The invention relates to a running belt for a treadmill device, comprising a tread portion having a running surface for a user to tread upon, a support portion, and a connecting portion between the tread portion and the support portion, wherein the tread portion is connected to the support portion by the connecting portion, and wherein the connecting portion comprises a lattice structure having a plurality of struts defining a plurality of cells of the lattice structure. Moreover, the invention relates to a treadmill device, a running belt slat, and a method of producing a running belt.

A treadmill includes two side frames, a walking board assembly mounted between the two side frames, and a walking belt encircling the walking board assembly. The walking board assembly includes a support plate, a shock-absorbing layer, a wear-resistant layer, and two thermal conducting strips. The shock-absorbing layer has a bottom face abutting a top face of the support plate. The wear-resistant layer has a bottom face abutting a top face of the shock-absorbing layer and the top face of the support plate. The thermal conducting strips abut the shock-absorbing layer and are arranged at a middle position of the support plate. Each of the thermal conducting strips has a front end and a rear end abutting the top face of the support plate. Thus, the wear-resistant layer completely covers the thermal conducting strips and the shock-absorbing layer on the support plate.

The disclosure relates to an exercise device, which includes a frame assembly, a running deck inclined at a predetermined angle relative to a base frame, a running belt, and a main cover. The inclined running deck, together with the main cover, provides space for accommodating the motor, which advantageously extends the area for the running belt. The present disclosure also provides an exercise system that includes the exercise device described above and a desk. The exercise system of the present disclosure allows users to engage in activities such as work while exercising.

A cardiac enhancement training device is provided. The cardiac enhancement training device includes an adjustable height assembly designed to change a height of a handrail of the cardiac enhancement training device. In one instance, the adjustable height assembly changes the height of the handrail by changing a height of an upper base including the handrail. In one instance, the adjustable height assembly is included in a plurality of support posts that support an upper base of the cardiac enhancement training device. Further, provided are system and methods for adjusting one or more operating parameters of the cardiac enhancement training device based on a plurality of user inputs.
