20-90LB Dumbbells Sets

Experience seamless strength training with 5-in-1 adjustability, offering five precise weight settings — from 2kg to 11kg (4.4 lbs to 24.2 lbs) — all in one compact design.
Simply twist the handle to instantly switch between resistance levels — no interruptions, no hassle. The one-handed adjustment mechanism changes weight in just one second, helping you maintain workout flow and maximize results.

Safety First

The dual locking mechanism ensures each plate stays firmly secured once lifted. The handle only turns when the dumbbell weights set is in its base, preventing accidental slips or plate drops. You’ll hear a reassuring “click” when it’s safely locked — so you can lift with confidence.

Built to Last

Each set of dumbbells combines a solid cast-iron core with a durable PE outer shell, making it rust-resistant and shockproof. The non-slip rubber handle offers a soft yet firm grip, reducing hand strain while keeping control during every rep.

Compact & Convenient

One cap dumbbell set replaces an entire rack of dumbbells. Its space-saving base includes finger grooves for easy movement and storage — perfect for apartment gyms or small workout spaces.

Take versatility to the next level. This innovative 6-in-1 set quickly converts between dumbbells, straight barbells, kettlebells, and push-up stands, giving you a complete home gym in one box.

The connecting bar lets you easily transform your dumbbells into barbells for close-grip presses, wide hammer lifts, or compound movements like deadlifts and squats.

Customizable Weight for Every Move

Adjustable weight plates let you fine-tune resistance for different exercises — from light toning to intense strength training — without buying separate heavy dumbbell set..

Slip-Resistant for Safety

Each piece is covered in premium neoprene and rubber, preventing slipping even during sweaty sessions. The upgraded handles are ergonomically designed to enhance grip and stability, helping prevent wrist strain and injuries.

Quiet, Floor-Safe Design

The rubber-coated plates minimize noise and protect your floors from scratches, making this the perfect option for early-morning or apartment workouts.

Full-Body Training

From arm curls and shoulder presses to squats and chest flys, this neoprene dumbbell set targets every major muscle group — arms, back, chest, legs, glutes, and core — offering a complete strength and conditioning solution for all fitness levels.
