I cursed and paused the app mid-set. It wasn’t the first time, second, or third (I stopped counting after that) that the steel from my weights bolt splintered into my fingertips, left unprotected with my gym gloves.

It wasn’t the only thing I disliked about my traditional adjustable disk dumbbells. The other issue was changing weights between sets: when one exercise requires 20 lbs and another requires 15, you need to unscrew the bolt, take out the 2.5-lb disks at each end, replace them with 5 lbs instead, and tighten the bolt again. Imagine you have four alternating sets like this, and you have to repeat it each time. It’s a pain.

Then there’s bulkiness. The disks are pretty big and flat, and I’m a small-ish guy. The size of the disks makes it hard to do certain exercises that require me to hold the weights close together or when I need to lower them to the floor, and their size prevents me from lowering the weight fully.

At some point in June, I decided to try Amazon Basics rubber hex dumbbells to see if it improves my exercise, and that got me pissed off - because I hadn’t thought about it sooner. The difference is huge.

Above, you can see the difference in size between the disk weights next to a hex one I got more recently. To the lower right, one of the bolts I have to tighten on top of a disk. These suckers are the one that keeps splintering. I am placing them on cardboard so I don’t scratch the floor.

With the new weights, I don’t need to switch between weights quickly, so my exercise sessions are more fluid and more fun. I can do the exercises as intended, improving my form and isolating the muscles I need to work on. The hex-rubber weights mean I don’t need to worry about the floor (the apartment has a white wooden floor, a genius idea), and they don’t roll away from me when I place them down. I can even use them for support as push-up handles. And no more splinters.
