Great product!
These dumbbells are the ideal solution for those who want to workout at home but don't have the space for a full set of weights. The weight adjustment could not be simpler and takes no more than a few seconds. Considering the versatility and adjustable nature of the product they feel extremely solid and stable. A little on the expensive side but worth it for the best of both worlds - many weight options without taking up the space!

Bowflex Selectech adjustable Kettlebell. - Amazing piece of kit
What a brilliant piece of kit not only because it’s very well made but being adjustable takes up virtually no space which is ideal for my home gym. Also the handle isn’t too thick unlike most kettlebells meaning exercises such as upright rows, shoulder workouts etc you are able to grip it with complete comfort. Excellent value for money as it’s equivalent to having 6 kettlebells.

Gym-Level Gains Without Leaving the House
I Purchased two sets of these. These Bowflex SelectTech dumbbells are easily one of the best additions to my home setup. I was tired of tripping over mismatched dumbbells and wasting time swapping plates mid-workout. These solved both problems in one go. The dial system is super smooth—just twist to your weight, lift, and go. It feels a little like unlocking a cheat code for home fitness. Whether I’m doing quick supersets or full-body workouts, it’s fast, efficient, and keeps things tidy. Build quality feels solid, and the grip is comfortable. The weights click in securely, so there’s no rattling or sketchy movement during use. It’s also way more compact than a full dumbbell rack, which is a huge win if you’re working out in a smaller space. Yeah, the price isn’t cheap—but when you consider you’re getting 15+ sets of dumbbells in one, it’s totally worth it. Plus, they just look cool. Bonus motivation. If you’re serious about training at home without cluttering your space, these are a no-brainer. Quietly awesome and super convenient.

Good quality weights that don’t take up much space
I bought this after using my sister’s kettle bell from the same manufacturer. I like the adaptability of having multiple weights condensed in one without needing a huge rack. It just hadn’t occurred to me that I would have to buy two in order to do many of my work out routines! And it’s expensive - a big investment which hopefully will last.

Good value, not best handle
I actually have two of these now, bought a second so I could train with two or if I have a training partner round. Both times I brought one it was on sale. Design: the shell for this product seems to be longer in drop than a standard kettle bell, the hand is a lot wider so makes some movements awkward. Reliability: I've never had any issues changing the weight value, it is smooth and works with ease. When doing kettlebell swings I worry the weight will come flying out but in over a year of use it never has so seems fairly secure. Value: Very very good for saving space, and providing a good variety of weights at a lower price point then buying them separately. Increments do not rise in fixed values which can annoying, for instance the sequence goes 11kg to 16kg then 18kg. Overall: Very Good value when I purchased at around £100each time, range of weights is good and system is easy to use. Only real issue is the width of handle is longer than standard Kettle bell which can change the why some movements may be done but any change should be only slight. I do use modular dumbbells (nuobell) and bar bell (bow flex) for training the majority of the time, but the kettle bell was the modular system I first purchased and it still comes in very handy, hence I brought a second.

Love these
I bought 2 of these and 2 of a cheaper brand that offers different increments. So I can swap between the 2 sets for smaller increases in weight than these alone offer. Compared to the cheaper brand these are far superior. The size is quite big which is a slight negative point for some exercises like Bicep curl. The weight plates are quite secure and solid in the handle whereas the cheaper one the plates are quite loose and can even be moved up and down. So it is worth buying these more expensive ones. The dial to select the weight is easy to see and easy to turn. This is also better than the cheaper ones I bought. I like that you can select the weight on each end which is not available to do on the other set. The only negative about selecting each end seperately is it takes twice as long as the cheaper set that uses a push button while turning only one end to select for both ends. This is not a deal breaker for me as it is still a very quick selection preccess. The positive of selecting each end seperately could be that you can have one weight on one and a different weightbon the other end. No idea why you would want to do that but these allow it and the cheaper ones don't. One negative is that the handle rings that hold the plates in is plastic and my research has shown youtube video's where people claim they have cracked or become loose which allow the plates to fall out. I don't know how true that is under normal use but the 'how to fix' video was very useful and they claimed they had had the set of dumbbells for 5 years. The tutorial gave me confidence to go ahead and buy rather than dissuade me. Knowing that parts can be available online and youtibe has step by step guides. As for use, I found videos on youtube where people were using these exact dumbbells. They showed how some exercises are negatively compromised regarded full range of motion and how you can adjust to account for it and still get the maximum out of the exercise. Be carefull when unpacking. I had to set them to a weight I could manage and remove the handles at that weight. Then remove each plate seperately. Then take the base out and re build the plates into it where I intended them to stay. Then place the weighet handles into the base.

Souhaitant poursuivre mon entraînement en salle à la maison du fait de la fermeture des salles de sport, j'ai commandé des haltères. Livrées rapidement, elles sont arrivées chacune dans un grand carton avec serres flex autour pour faciliter la saisie (et ont été livrées dans la pièce de mon choix par deux livreurs très sympas). Dans le carton, un énorme emballage en polystyrène entoure chaque haltère, qui est bien attachée à son support. Mise en place aisée, rien à monter à part enlever la "ceinture de sécurité" de chaque haltère la retenant à son support. Le mécanisme de choix du poids est en métal et semble solide, le poids sélectionné se mettant très bien en place sans aucun jeu dans la molette. Evidemment il est hors de question de les lancer, mais l'ensemble du choix de poids est top, le changement se fait très facilement en reposant l'haltère sur son support. Elles sont massives, plus que des haltères de même poids habituellement, mais le grip est bon. La poignée fait un peu mal lorsqu'on augmente le poids, obligeant au port de gants (c'est la première fois que ça m'arrive alors que je mettais 2x46kg au DC haltère sans soucis), car dès les 30 kgs passés l'irrégularité au niveau de la poignée commence à écraser les métacarpiens de la main et cela est assez gênant selon la position. Pour du sport à domicile, couplez la avec un banc et vous êtes les rois du pétrole. Ca semble cher à l'achat mais c'est ultra polyvalent et permet de faire énormément d'exercices différents.

Great addition to the gym. One kettle bell, different selection of weights.

Perfect zoals verwacht

Okay, I bought 2 of these. Changing the weights works 'alright'. It really doesn't work perfectly. Especially not when you're in a workout and thus probably shaking / sweating / heavily breathing. In that case changing the weights won't go as smooth as you'd expect from a dumbell at this price level. The concept is great. But the materials used are insanely weak. It's all plastic. If you want to enjoy these dumbells for a couple of years, you'd better treat them as if they're made from glass. So no bumping, no dropping, and always using great caution when putting them back in the base, or when changing weights. Not what you'd want with dumbells. I seriously don't understand why Bowflex doesn't improve the materials they use. Or actually, I do understand. Bowflex is probably just in it for the quick sales.

Mi review es de la pesa rusa, o "kettlebell", y estos son los pros y contras que le veo. Pros: - En una sola pesa tienes 6 pesos diferentes. - Ahorras muchísimo espacio. - Es muy fácil cambiar de peso. Contras o áreas de mejora: - La cubierta al ser de plástico muy delgado, se siente frágil, hay que tratarla con cuidado. - De 11kg se brinca a 16kg, es decir, no hay nada en medio y brinca 5kg, que me parece mucho. - El "plato" que queda abajo sosteniendo las pesas que no se necesiten, también se siente fragil. En general estoy contento con el producto, aún con los detallitos que menciono.
