How to use

Select the desired load using the dumbbell's automatic adjustment system to change weight in 2 kg increments. Ensure the plate selector or adjustment mechanism fully engages before lifting, and adopt proper lifting technique for each exercise: maintain a neutral spine for presses and rows, control the descent during eccentric phases, and use a full range of motion where appropriate. When not in use, place the dumbbell on a stable surface to prevent rolling and check the adjustment mechanism periodically for secure engagement.

Recommendations

Begin with lighter loads to rehearse movement patterns and increase weight in 2 kg steps as strength improves. Use this adjustable dumbbell as part of a structured program that includes adequate warm-up, progressive overload, and recovery periods. Regularly inspect the cast iron surface and adjustment mechanism for wear, and avoid dropping the dumbbell from height to preserve the finish and mechanism.
