We don't see too many people complaining about the 50mm olympic plate. The textured surface allows athletes to grip all the weight plates securely easier. Compared to more cylindrical designs where a little bit of slip might place you on your toes, this feature increases safety and enables a lockup further back that allows for more direct force to be applied to the bar in case of falling. Also, high-quality materials that prevent rust are used, and they last a really long time even when facing decreased workouts. That versatility makes them good for many workouts, from deadlifts and squats to the bench press. In short, if your customer gets one of these weight plates instead another then the only practical benefits to him are:- first, an added muscle strength, second, better athletic performance and in Third is a good investment of time in his health
