DS2 5-in-1 Dumbbell Set

These are awesome! Easy to use, great quality, and so versatile. We were looking for something that didn't take up a ton of space, so being able to use these in many different forms is perfect. They are easy to hold, and have soft edges so you don't need to worry about harming your floors/surfaces. Totally work the money for a good at home workout.

DB3 5-in-1 Hand Weights

These actually work great the quality is amazing. I was shocked when I receive these. The grip on it is good. It works very good. I love the color because it matches my room which is a light blue. The way options is crazy. I haven’t even reached 10 pounds yet and I love how I have the option For different weights. The size is great. It doesn’t take up too much space of the width of the item and it is a great workout. Definitely a five star purchase happy with this product.

Comfortable bar with good knurling for curling

I wanted a basic curl bar that the kids and I could use in the garage. I picked this one because the dimensions, weight, and angles seemed right, the ends were solid, it had clips, and the ends rotate. It arrived in a single rectangular box without any damage. I've used it about a week and am very happy with it. It feels similar to bars I've used in the gym and has bends in the right places. The ends rotate the way they should and the clips are fine. I really like the knurl (ie, the diamond pattern)- it gives a good grip but the pattern doesn't cut into my hands the way my regular bench bar does. The bar feels solid enough that it could hold a lot of weight.

Great for the price. Tweaked for taller person

Rows good and gives a good workout. Fairly easy to put together. Arm was short for a taller rower so I extended it and now it perfect. Row arms should be adjustable. Good value.

4-in-1 Leg Extension & Curl

Easy to assemble, perfect for my home gym. Good quality, nice bright orange matches the other equipment nicely. Smooth range of motion, good solid piece of equipment. Easy transition from leg extension to leg curl. Not sure how many weight plates it will hold as currently I’ve only been using 1-25lb plate to start with. Very happy with my purchase.

3-Grip Chest Press 1250 lb

Really nice weight bench. Seat itself is a little wobbly. Should have been more sturdy but good for the money.

About FEIERDUN

Why we build FEIERDUN adjustable dumbbells

We started FEIERDUN with one stubborn problem: a home gym full of traditional dumbbells takes over the room. A full rack of fixed pairs from 5 to 50 lbs needs a wall, a stand and a lot of money. Our first adjustable dumbbell set put that whole range of weight into one box that fits under the bed, and our 5-in-1 design went further — the same handle and weight plates become a barbell, a kettlebell and a push-up stand. Dumbbells, barbells, kettlebells and plates from one weight set: that versatility is the reason FEIERDUN adjustable dumbbells are where so many home gyms begin.

Think of the DS2 as a transformer. Thread the barbell connector between two handles and you have a bar for squats and good mornings, with thick foam so the neck stays protected. Swap to the kettlebell grip for swings, flip the plates into a push-up stand, and the same set gives you an endless workout without buying more equipment. Iron-sand plates stay quiet on the floor, and the locking knobs keep every plate where you set it.

Three families of adjustable weights

Today FEIERDUN adjustable dumbbells come in three families. The DS2 5-in-1 sets run from 20 to 90 lbs and replace four or five separate pieces of equipment. The DB3 in-1 adjustable dumbbell pairs twist between five light loads, 2 to 10 lbs per hand, with a dual-lock mechanism and a comfortable soft grip for toning and Pilates. The DB1 and FDB dial dumbbells change weight with one hand in a second, with 2.5 lb or 5 lb steps, a storage base and a non-slip handle — the fastest way to train supersets at home.

Every design follows the same rule: choose the weight, lock it, lift with confidence. Dial dumbbells adjust only in their base and lock the moment you lift. Plate sets use threaded collars that stay tight through presses and rows. Square DB3 heads stay put on the floor. Small things, but they are why big lifts feel safe in a small room.

Space-saving design for real homes

A pair of FEIERDUN adjustable dumbbells takes the space of one pair of fixed weights, and one base or box replaces a whole rack. That space-saving design matters in apartments, spare bedrooms and one-car garages, where every square foot of floor is shared with life. When the workout is done, the set goes back in its base or under the bed and the room is a room again.

Pros we hear from people who train with us: more strength training per dollar, quick changes between exercises, and pairs that grow with them from the first year to the fifth. The trade-off is honest too — a dial dumbbell is a little longer than a hex dumbbell, and plate sets take a minute to change.

From dumbbells to a full home gym

A dumbbell set is where most home gyms begin, but rarely where they end. That is why we also make color Olympic bumper plates and bars rated to 1900 lbs, a chest press with spotter arms, a power cage with a cable crossover, leg extension and leg press machines, a hip thrust station, a stair stepper, a rower, a vibration plate and a massage gun for recovery.

Each station is sized for real homes and backed by our support team, with a 3-year warranty (FEIERDUN Care+) on our DS2 and DB1 dumbbells and year warranty coverage on many machines. Join FEIERDUN, stay consistent, train in the space you already have, and enjoy fitness every day without the commute.

Questions we hear most

Are FEIERDUN adjustable dumbbells good?

Our DS2 set alone carries thousands of ratings with an average around 4.4 out of 5 stars. People choose it for the 5-in-1 design, the quiet iron-sand plates and the price of a full weight set in one box.

What are the downsides of adjustable dumbbells?

Plate-loaded sets take a little longer to change than a dial, and dial dumbbells have a longer handle than a fixed hex dumbbell. In return you save space and money compared with a rack of traditional dumbbells.

Which FEIERDUN dumbbell is best for a beginner?

The DS2 30 or 45 lb set for all-round training, or the DB3 hand weights if you mostly do toning, cardio and Pilates.

How do I order, track or return a FEIERDUN product?

Orders are placed and fulfilled through our partner store. Tracking, returns and warranty claims run through the order page of the store you bought from.

Do the machines need weight plates?

Our chest press, leg extension and leg press machines are plate-loaded. Many come in packages with plates, or pair them with our color bumper plates.
