Adjustable Dumbbells Power Block Dumbbells 42kg Set of 2 Adjustable Dumbbells Muscle Training Block Dumbbells One-Touch Adjustment Adjustable Weight Training One-Year Warranty Dumbbells Adjustable Weight Dumbbell Set Block Dumbbells Home Arm Exercise Gym Muscle Training Goods Muscle Training Equipment Big Sale You can choose from three types of dumbbells: a maximum of 23kg/26kg for those who want to challenge themselves without overdoing it, and a maximum of 42kg that even bodybuilders will be satisfied with! The sides of the plates are designed to be flat so that "on the knee," which is essential when using heavy dumbbells, is possible. Also, because the weight can be changed quickly, it is suitable for high-level training such as "super sets" and "drop sets." Just insert the locking pin. Weight can be changed in just 3 seconds. The simple structure of just securing the plates on both sides of the core (handle) with locking pins eliminates the worry of breakdowns like dial-type dumbbells. There is no stress such as "the adjustment is not working well..." or "it takes skill...". Because they are adjustable blocks, you can do various training without going to a training gym. 【Product Size】 42kg: 42cm x 19.2cm x 19.8cm
