    • Best excercise product I've ever purchased
Definitely the best thing I've ever purchased for exercise. The convenience of this kettle bell has really got me working out and enjoying it. I bought this during COVID quarantine and it has been a perfect purchase. The small package is great. It has a range from 8 to 40 lbs in a small kettlebell form that doesnt take up much space. The unit comes with a base where you set the weight before you make an adjustment. Just the click of the dial and you are set with a different weight. The convenience of switching weights is what has me doing more and more variety of exercises. If I had any negatives for the product, it jumps from 25 to 35 to 40 in the available selections. I would have loved a 30lb setting built in, but it has quite a range in a very compact package, so I think they did a great job designing it. The durability is great. It does say that you cant drop it or throw it down, but that isnt really a problem to me. Overall, I am extremely happy with this product and I am already seeing muscle gains from using the product. I think the price is very reasonable for the weight range and convenience it provides. If I would have bought dumbells with plates, I wouldnt do nearly the mix of exercises, because I'd get tired of putting plates on and taking them off during a workout. With the Bowflex, I'm setting the weight down on the base, turning a dial a click or two and lifting it right back up. Love it! HIGHLY RECOMMENDED! ... show more

    • Make the self commitment.
If you’re considering this piece of exercise equipment, it is definitely worth the value. It is a very well-made and sturdy tool and it’s the absolute best investment you can make for yourself. You won’t regret it.

    • Space-Saving and Versatile
I’ve been using this adjustable kettlebell at home and it’s been a practical solution for strength training without taking up too much space. The dial mechanism on top makes it easy to switch between different weight settings, and it locks in securely. I can move from one exercise to the next without needing a full set of kettlebells around me. The grip is comfortable and solid. It’s shaped more like a traditional kettlebell than I expected, which helps with swings, presses, and squats. The weight distribution feels even, and it doesn’t shift during movement. That was something I was concerned about with adjustable equipment, but it hasn’t been an issue here. It’s also easy to store. I keep it in the corner when not in use and it doesn’t clutter the room. This has worked well for full-body workouts at home, and it’s nice having multiple weights in one piece. Overall, it’s been a solid addition to my routine and a good fit for small spaces or anyone wanting to keep their setup simple. ... show more

The media could not be loaded. The Bowflex SelectTech kettlebell is a game changer for my home gym. It’s super easy to adjust the weight with just a quick turn of the dial, and it replaces multiple kettlebells in one compact design. The build feels solid and durable, and the grip is comfortable for all kinds of exercises—swings, squats, presses, and more. It’s a great option if you’re short on space but still want a variety of weight options. Definitely worth the investment for anyone looking to level up their home workouts without cluttering the room. ... show more

    • Great for beginners.
Like many folks, I bought a bunch of home gym equipment during the pandemic, and this Bowflex Kettlebell was part of that. I’ve enjoyed using it, but once I bought actual kettlebells, I started to see the limitations of this product. Cons: - For one, it’s housed in plastic. It’s sturdy enough, but still there's always a chance putting it down too hard might break it. - The handle is my biggest gripe. It’s skinny and smooth, so it doesn’t provide the best grip. - Differences in weight are a bit weird: 8, 12, 20, 25, 35, 40. I absolutely noticed when I went from 25 to 35. It’s a big jump. I bought a 31 pound (14kg) kettlebell just to fill that gap. Coincidentally, that was when I really saw the differences between this and real kettlebells. - Once you start working with real kettlebells, it’s hard to go back to this one. All that being said, I’m still happy with my purchase. It’s a great starter kettlebell for sure, and I definitely got a solid two years worth out of it. I’d recommend it mostly for swings and rows, which is what I still occasionally use it for. ... show more

    • Great Addition to My Home Gym.
Four years strong and still going—this sleek kettlebell swaps six weights in one, keeping our home workouts powerful and clutter-free. The size is perfect for small spaces (or large) just very compact and exactly what I was looking for. The weights easily adjust and the grip has always provided what I need for even the smallest of settings. And now Peloton has their own section for kettlebell workouts and I'm soooo excited! ... show more

    • Space saving, easy to use
Space saving, easy to use - much better than storing a bunch of kettlebells in varying weights, especially if your storage or workout space is limited. High quality locking mechanism that feels very secure when lifting.
