UNNMIIY 4-in-1 Free Weight Adjustable Dumbbell Set with Foam Connecting Barbell Rod, Kettlebell Handles & Push-Up Stand Base

The UNNMIIY 4-in-1 Adjustable Dumbbell and Barbell Set is a space-saving powerhouse designed to deliver an exhaustive strength-training repertoire within a single modular system. By replacing four separate pieces of bulky commercial gym equipment — traditional dumbbells, straight barbells, kettlebells, and push-up stands — this set empowers home fitness enthusiasts to execute comprehensive push-pull-legs splits, deadlifts, bench presses, and kettlebell swings on a budget.

Engineered with an impact-resistant PE outer shell encasing a dense iron sand and cement composite core, the weight plates eliminate the loud clanking, rust formation, and floor scuffing common to cast iron weights. The kit includes a thickened 20mm ergonomic foam connecting rod that links the two dumbbell handles into a comfortable barbell, cushioning the neck and upper trapezius during heavy back squats and hip thrusts. Reinforced double-lock screw nuts ensure plates stay rigidly immobilized during lifts.

Versatility is unmatched: attach the included kettlebell base and dual handles to perform swings and Turkish get-ups, or use the handle grips as ergonomic push-up stands to deepen chest range of motion. With rapid plate reconfiguration and tactile non-slip diamond-textured grips, the UNNMIIY 4-in-1 system delivers an all-encompassing hypertrophy and strength experience.
