No need to purchase multiple pieces of equipment. It's space-saving, convenient to store in your bedroom, living room, or study, making home workouts easier. ● Ready to use upon unboxing, no assembly required Completely tool-free design. Use it right out of the box, no tools or installation procedures needed. This is more user-friendly for fitness beginners or those who aren't adept at DIY. Start your fitness plan immediately. ● Comes with a dedicated base for safety and convenience Includes a dedicated storage base that stably holds the dumbbells, preventing direct contact with the floor. This not only protects your floor from scratches but also facilitates storage and maintains tidiness. ● Difference between [Internal Spiral] and [External Spiral] Compared to external spiral designs that suspend plates with metal hooks, the internal spiral adjustable dumbbell uses a full-circle latch to secure the weight plates. This provides a more stable structure and higher safety, ensuring every workout is more secure and smoother. 【12-90 lbs Product Specifications】 Material: Base: PP Polypropylene / Weight Plates: Solid Steel Dumbbell Dimensions: 46x22 cm (±10%) Base Dimensions: 49x24 cm (±10%) Weight: 40.8 kg (±10%) Volume: 55x31x35 cm (±10%), cannot be picked up at convenience store
