The Bowflex SelectTech 840 kettlebell is a solid option if you’re looking to workout with kettlebells.
It’s six kettlebells in one and doesn’t take up a lot of space.
For me, it was the perfect option for my garage gym.
Unboxing the Bowflex Adjustable Kettlebell
Table of Contents

The Bowflex adjustable kettlebell comes fully assembled in a box surrounded by thick styrofoam.
It comes with several instruction manuals in different languages.
The kettlebell came without any dents or scratches and is ready to use right out of the box.

Once you pull the kettlebell out of the box, you can see it’s made with quality materials.
The handle feels solid.
The knob has a thick rubber grip.
And the outer shell (hull) is made of a heavy duty material.

From the side, it looks just as awesome and you can tell they put a lot of work in building this quality kettlebell.
Features

The Bowflex SelectTech 840 kettlebell comes with four weight plates that are inside the kettlebell hull.
They stack on top of each other and whatever weight is not selected stays on the base.
This works similar to other Bowflex products like their adjustable barbells.
The bottom part is the base and it always stays on the ground.

The top of the kettlebell has an adjustment knob that lets you select the weight you want.
It rotates in both directions.

You’ll hear a click each time you rotate the knob to a weight selection.
That click tells you your weight selection is securely locked and ready to lift.
Locking Mechanism

The Bowflex 840’s locking mechanism selects the weight off the base and makes sure it stays inside the kettlebell.
You can see the selecting shaft that locks the weights in place if you flip the kettlebell hull over.
In order to rotate the adjustment handle to change weights, the kettlebell MUST be on the base.
This is done for your safety.
They want to make sure the weight plates don’t fall off when the kettlebell is not on the base.
Weight Increments

There are six weight increments on the dial and they are shown in kilos and pounds.
The weight increments go like this:
- 8 lbs (3.5 kg)
- 12 lbs (5.5 kg)
- 20 lbs (9 kg)
- 25 lbs (11 kg)
- 35 lbs (16 kg)
- 40 lbs (18 kg)

Maintenance and Safety

The Bowflex 840 is not meant to be dropped.
They make it very clear by engraving a “Do Not Drop” sign right on the adjusting knob.
Dropping the kettlebell can damage the plates and the locking mechanism.
The last thing you want is for one of the weight plates to drop on you while you lift the kettlebell overhead.

Bowflex provides you with a library of kettlebell exercise videos.
You can learn to do cool exercises like the Turkish Get Up, Gorilla Row, Single Arm Swings, and more.

Bowflex SelectTech 840 Alternatives
Powerblock Adjustable Kettlebell

The Powerblock adjustable kettlebell is one of my favorite adjustable kettlebells because of its build and simplicity.
It’s made out of solid steel with cast iron weight stacks so it’s almost impossible to break.
It has a weight range of 35 lbs to 62 lbs and I adjust it just like a weight stack by pulling out a pin and selecting the weight I want.
Everything else stays on the floor.
Rep Fitness Adjustable Kettlebell

The Rep adjustable kettlebell uses a similar adjustment mechanism like Bowflex but the outside is all metal.
It has 5 weight increments that are adjusted by turning a dial at the top of the kettlebell.
Freak Athlete Adjustable Kettlebell

The Freak Athlete adjustable kettlebell is an 11-in-1 kettlebell with a weight ranger of 12-32kg (24-70 lbs).
This one goes up in 2 kg (4.4 lbs) increments so it makes small jumps.
It uses a magnetic pin similar to the Powerblock kettlebell.
Where to Buy Bowflex SelectTech 840 Kettlebell
You can buy the Bowflex 840 kettlebell from two places.
Directly from Bowflex’s website or through Amazon.
Both places have the same price and offer FREE shipping.
Don’t know how fast Bowflex’s shipping time is, but with Amazon Prime, shipping is pretty quick.
Conclusion
Overall, the Bowflex SelectTech 840 is a solid kettlebell.
Well built, replaces 6 kettlebells, and takes up very little space.
I originally bought one to test it out, but now that I’ve put it through the ringer I’m sold.
I’m getting the another one to have the pair.
