FOR SAFE TRAINING: Our weights with screws are precisely cut from solid steel without any welding. This safe design can help you focus on the exercise all the time because you don't have to worry about the screws that hold the plates in place loosening and plates wobbling during exercise. SUITABLE FOR HOME USE: The dumbbells are compact and can stand upright, making them easy to store. Most importantly, they do not give off any odours, which is a benefit for your workout and storage at home.The upgraded silicone rings easily fit over the end caps, protecting the dumbbells and your floor. EASY WEIGHT ADJUSTMENT: The weights are marked on each plate for quick identification. Thanks to the no-nut design, you just unscrew the plates to adjust the weight quickly. The barbell attachment also gives extra diversity in workout options.
