We designed a smart IoT personalized health training device. It was configured according to the characteristics of the health device, and the design line was set to fit the convenience of use with a 1:1 size ratio considering ergonomic elements. Considering the LCD display mounting part on the product side, the design was organized according to the thickness and installation and assembly, and it was configured with a round extrusion banding method so that it can match the interior space of the gym.
