4-in-1 Multifunctional Dumbbell Set: The UNNMIIY adjustable dumbbell set provides versatility with a pair of dumbbells that convert to barbells, kettlebells, and push-up stands, enabling a comprehensive range of exercises including bench presses, squats, and more.

Premium Construction: Crafted with environmentally-friendly materials, the dumbbell exterior combines cement and iron sand with high-quality PE materials. The interior mixture of iron, mud, and sand effectively protects floors from abrasion while deep grooves ensure optimal grip.

Enhanced Comfort: The connecting rod features a 5mm thick steel tube covered with 20mm high-density foam. Its ergonomic curved design conforms to the neck, offering a non-slip, sweat-resistant surface that delivers superior comfort during workouts.

Professional-Grade Design: The dumbbell bars are manufactured from ABS environmental material with textured non-slip surfaces, maximizing friction for improved control and stability throughout your exercise routine.

Advanced Safety Features: UNNMIIY's locking nuts provide enhanced security compared to standard multifunctional dumbbells. The thickened nut threads securely lock dumbbell plates in position, eliminating movement and ensuring maximum safety during use.

Customizable Resistance & Space-Efficient Storage: The detachable design allows weight adjustment from 2lbs to 22.5lbs per dumbbell, accommodating progressive training needs. The compact footprint requires less than 2 square feet of storage space while offering simple assembly.
