The sides of the plates are designed to be flat so that "on the knee," which is an essential condition when using heavy dumbbells, is possible. Also, since you can quickly change the weight, it is suitable for high-level training such as "super sets" and "drop sets." Just insert the locking pin. You can change the weight in just 3 seconds. It has a simple structure that only requires you to secure the plates on both sides of the core (handle) with locking pins, so you don't have to worry about breakdowns like with dial-type dumbbells. There is no stress such as "the variable is not working well..." or "it takes skill...". Because it is a variable block, you can do various training without going to a training gym.
