UNNMIIY Adjustable Dumbbells 5‑in‑1 Set — 20/30/45/70/90 lb Options, Converts to Barbell & Kettlebell, Space‑Saving

UNNMIIY Adjustable Dumbbells are a compact, 5-in-1 home weight set that converts between dumbbells, a barbell, kettlebell and push-up stands so you can progress from light to heavy training without bulky racks.

Train more effectively at home with a single, space-saving package. This adjustable free weight set from UNNMIIY combines interchangeable weight plates, secure locking nuts, and ergonomic handles so you can switch between exercises quickly. The pieces use high-quality PE with iron, mud, and sand infill for solid weight feel while foam and textured ABS surfaces keep grips comfortable and slip-resistant.

How do I change the weight and switch between dumbbell, barbell, and kettlebell?

Adjusting weight is tool-free and straightforward: remove or add the detachable weight plates and lock them in place with the upgraded nuts. To transform the setup, slide the connecting rod or handle into place and secure the same plates — the design supports multiple configurations so one set handles many exercises.

• Detachable plate design allows single dumbbells from 2 lbs up to 22.5 lbs each.
• 5mm steel connecting rod plus 20mm foam sleeve converts to a short barbell or kettlebell handle.
• Thickened locking nuts with reinforced threading prevent plate movement during reps.
• Installation and changes are quick — no special tools required.

What materials and safety features protect my floors and hands?

The weight plates have a PE exterior over a dense mix of iron, mud and sand that reduces impact noise and scuffs compared with bare metal plates. Grip surfaces combine a curved foam sleeve for the connecting rod and textured ABS bars to reduce slipping and increase comfort during higher-rep sets.

• PE-coated plates cushion floors and lower clatter than cast-iron plates.
• Deep grooves on plates and non-slip ABS handle textures improve control.
• 20mm thick foam on the connecting rod adds neck/chest comfort for press movements.
• Upgraded thicker nut threading locks plates more securely for safety.

Which workouts and progressions can I do with this adjustable set?

This kit supports strength and conditioning moves like bench press, bent rows, squats, lunges, kettlebell swings, and push-up variations using the included push-up stands. Because plate sizes are incremental, you can add small amounts of weight to progress gradually or combine plates to reach heavier loads when needed.

• Upper-body: presses, rows, curls, shoulder raises using dumbbell or barbell setups.
• Lower-body: goblet squats, weighted lunges, and deadlift-style movements with heavier combinations.
• Core and conditioning: kettlebell swings and rotational moves when configured with the handle.
• Bodyweight assistance: push-up stands provide wrist support and deeper range of motion.

Who this set is for: If you want a versatile home gym solution without buying separate dumbbells, kettlebells, barbells and stands, the UNNMIIY adjustable set suits beginners through intermediate lifters who value small-footprint equipment. It’s especially useful for apartments or compact home gyms where storage under two square feet matters. Choose this set if you want progressive resistance, quick conversions between exercises, and durable, floor-friendly construction backed by brand support.
