Bowflex Kettlebell Review

We bet most people are drawn to kettlebells because they look cute and cool. Sure, they’re easy to use and swing around compared to other strength training equipment, but make no mistake. These round metal balls with handles on them are heavy too. In fact, kettlebell weights can range from 8 to 105 pounds.

The problem, though, is choosing the appropriate kettlebell weight for you. Some are heavy, others are expensive. So, the best way to go is to choose an adjustable kettlebell, such as the Bowflex kettlebell.

Product Description

This Bowflex SelectTech 840 Adjustable Kettlebell is your ultimate adjustable kettlebell. 

Six kettlebells in one, this Bowflex SelectTech 840 has a quick change mechanism. Its 15-pound weight handle can be adjusted between 8 to 40 pounds.  Simply turn the dial and choose the resistance you want for your training. That way, you can perform full-body exercises and quickly switch from one exercise to the next.

This advanced design of Bowflex SelectTech 840 Kettlebell was also created with portability in mind. It allows you to scale your workout needs without buying two or a set of standard kettlebells. You won’t even need to buy a kettlebell rack to store this fitness equipment!  The unit is small; you can guarantee it will only occupy a little space in your home gym.

Bowflex kettlebell is easy to use. It may just be a challenge for beginners to change weights but they’ll get used to it along the way. And as they get familiar with locking and unlocking the weight plates, they can consider it a short break in between their training sessions. After all, a short rest is important to increase muscle endurance too.

Bowflex truly did a great job in combining stability, functionality, and a great look in making this exercise tool. Also, it has durable molding around the metal plates and a metal tab to secure the weight.

Is it worth it?

In terms of its build quality and function, the SelectTech 840 Adjustable Kettlebell is worth it, especially if you prefer two-handed kettlebell workouts like goblet squats and kettlebell swings.

At first look, you may be thinking that the shape of this kettlebell is more cylindrical and wider compared to traditional bells. But it’s not really an issue. 

In fact, it’s ergonomic with durable molding. Just hold the handle firmly so that it is turned away from you as you perform exercises. You may also simply hold the adjustable weight on the sides. That way, it will be horizontal even in the topmost position.
