【Excellent Craftsmanship ATIVAFIT's weight plates are made of pure steel, cut and shaped as a whole, making them resistant to rust, aging, and cracking, ensuring a long lifespan. The curved handle is wrapped in rubber for enhanced grip without causing hand injuries. The tray is made of industrial-grade high-strength material, lightweight yet sturdy, and offers shock absorption and noise reduction effects. The bottom groove allows for easy daily handling, use, and storage.

【 Ranging from 5.5LB to 55LB, with 10 levels of weight adjustment (5.5, 11, 16.5, 22, 27.5, 33, 38.5, 44, 49.5, 55LB), it perfectly meets the diverse needs and plans of beginners and professional fitness enthusiasts for strength training. The incremental/decremental adjustment of 5.5 pounds per level maximizes muscle stimulation while minimizing the risk of exercise-related injuries.

【1s Operation with One Hand】When the safety lock is unlocked, simply rotate the weight selector dial on one side gently, and the weights on both sides of the dumbbell will be adjusted simultaneously and smoothly. This greatly surpasses other adjustable dumbbells where both hands are required to precisely adjust the weight selector dial to ensure consistency or where significant force is needed to adjust the weight by rotating the handle.

【Dual Safety Protection】ATIVAFIT employs a dual safety lock design. Firstly, the red button must be pressed to release the safety lock before the weight plates can be moved or detached for adjusting the dumbbell's weight. Secondly, the weight adjustment can only be done on the tray. This structure ensures your safety during use and prevents the weight plates from accidentally falling off during exercise.

【90% Space Saving】With 10 levels of weight adjustment, owning a single ATIVAFIT adjustable dumbbell set is equivalent to having 10 regular dumbbells. Coupled with the tray for storage, it significantly reduces the space required to store dumbbell equipment, saving up to 90% of space. No need to spend time and money at the gym, you can now train even at home.

【Live a Better You】The package includes a dumbbell set, an instruction manual, and a dumbbell exercise guide. In this illustrated guide, you will easily find suitable training movements for the body parts you want to exercise.
