  • What is the Best Adjustable Kettlebell for You?


I am the kind of person who gets bored easily. This goes for food, movies but especially WORKOUTS. If you ask me to do the same thing, with the same equipment it takes away the fun and novelty. That’s why I am always on the lookout for new equipment, something that will keep me on my toes. I’ve found that kettlebells are impossible for me to get bored with and I’ll tell you why.


They go beyond our traditional gym equipment of bands, dumbbells, and barbells, with their unique shape and dynamics. There is so much versatility in the way the kettlebell moves that I need to be really present when I am working out. Most important of all it’s the ultimate 2-in-1 as I get my strength and my cardio all at once. 


Adjustable kettlebells make sense for a home gym. There’s only so much space we have and we want equipment that can progress with us, instead of needing to purchase additional equipment. 


Our Picks for Best Adjustable Kettlebells:


Best Overall: Bowflex SelectTech 840 Kettlebell

This is our selection for the overall best adjustable kettlebell thanks to its easy weight adjustment mechanism, with a simple switch of the dial you switch the weights. The design is similar to a traditional kettlebell and it is equipped with an ergonomic handle.


Another reason this made the best adjustable kettlebell list is the weight range. With six different weights, it’s one of the options on the list with the best range, and that helps with different exercises as well as our progression as we improve.

Granted this product doesn’t look like our other best adjustable kettlebells on the list and that’s because it’s so much more than just a kettlebell. This beauty is made of durable PVC that is burst-proof and comes with a one-way valve to be filled with water. 


Working with a water-filled weight means that you activate your core muscle in every move to keep your balance.  Having two handles instead of one also increases the variety of workouts you can do. 


Its soft and bouncy body makes it user-friendly, so you don’t need to worry about scoffing your floor or hitting your knees! This also wins the best portable adjustable kettlebell since you can pour the water out, fold it up and take it to the beach or traveling.

This product is on the high-end luxury end of the spectrum of our best adjustable kettlebell list, the Chanel of Kettlebells if you will. They back up their expensive price tag with a five-year warranty. Different from most of the cast iron options on the list this is made of alloy steel.

What is the best adjustable kettlebell for you?

Keep in mind a good weight to start your kettlebell journey is around 6 kg for women and 8 kg for men. This will allow you to learn the movements and develop proper technique and form for the different exercises. 


When deciding which adjustable kettlebell better fits your workout routine consider if you have previous experience with kettlebells to know which weight range would suit you best. 


Think about your budget, we want the best without breaking the bank at the same time.


Another element to review is if you need portability in your adjustable kettlebell, where the Fluid X Boba beats the others in the list. I also love the sense of security I have when working out with the Boba 13, I don’t have to be scared of going hard and banging myself up. 


There are tons of benefits to using adjustable kettlebells as they save space, improve your balance, and work strength and cardio at the same time.


When you are clear on what are your needs, get the right kettlebell for you and go start those swings!
