By definition, a bench press is an exercise that involves raising a weight but at CES 2019, Hiiga-One was introduced as a revolutionary mechanical, weight-free workout system.
The mechanical bench press machine looks like a pared-down workout machine, as it has only two light strips supporting either side of the barbell. With this system, users are able to enjoy a safe experience that requires no spotting, as well as one that's challenging—users are able to change the weight they're lifting with ease.
Due to the intelligence of the system, the Hiiga-One is capable of responding to one's progress over a workout. For example, as a user's energy decreases, the weight is reduced slightly and the effectiveness of the workout can be gradually increased.
