Love this kettlebell

Love this kettlebell! The adjustable weight system is quick and easy to use, and it saves a ton of space compared to owning multiple kettlebells. It feels sturdy, works great for a variety of exercises, and has been a fantastic addition to my home gym. Highly recommend!

Purchased 2 and I don't Regret it

Since purchasing this product, I've lost 27lbs. I currently have CHF (congestive heart failure) and a pretty severe case of it. My heart functioned only at a 25% capacity but after 2 months of using my kettlebells and incorporating them into my workout routines, my heart has been gradually getting stronger. I go to cardiac rehab 3 days a week and not only myself but my nurses are surprised of my weight loss and my cardio clearly getting stronger. I ordered the bowflex dumbells and barbell/curved barbell with the stand to step up my game and continue my fitness journey

Seller Verified Purchase

Worth it

This was my first purchase from Bowflex. I was hesitant because of the price point considering how much basic kettlebells are but when you consider storage and was of use and just not having to have tons of different weights around it's so worth it. They're incredibly easy to use, the packaging was great and they're amazing to work out with.
