    Better than Power Blocks

    It is very versatile and feels more like dumbbells.
    I am enjoying these a lot. They're great! Highly recommend.

    James R. (New York, US)
    Great value, awesome quality.

    Very happy with these dumbbells.
    They're easy to assemble, easy to use, evenly balanced not super blocky.
    Plates are sleek, I like how they are powdered coated, and did not chip when I clanked them accidentally against other metal objects.
    They are easy to adjust and the price came with the stand. A lot of these other dumbbell sets you have to pay for the stand separately, but these you had adjustable weights with the stand at an unbeatable price. Also very space-efficient compared to a full rack. One of the best gym equipment I own, hands down.

    Robert (Atlanta, US)
    Positively Surprised

    The price was reasonable and the shipping time was short, so I was skeptical. I’ve lifted with them a few times now, and they work better than I’d hoped.

    Nichole Corless (Clovis, US)
    Awesome adjustable weights!!

    We ordered these about a month ago. They arrived quickly! Easy to put together stand. The weights are well made. I love the thin plates and no knob on the end which makes for a flat surface for resting on your legs. The adjustable knobs are on the top by the handle and easy to switch between weights. The stand is super nice and make racking easier! Both my husband and I love having this addition to the home gym we're building. High quality, definitely recommend!

    Jared (Delaware, US)
    MX55 dumbbells and stand

    So first off these weights are fantastic. I owned the bow flex adjustable dumbbells and these blow them out of the water. They feel like a normal dumbbell no matter which weight you choose. Needless to say they are awesome and I’ve loved them so far! Second, competitors outlet is GREAT! And I’m not just saying that...not only did they have the best price on these, but they also communicated and let me know what was happening with every step of my order. Will for sure buy from them again!
