You might have seen this heavy rubber handles before, but you might not have taken notice of them. Called FatGripz, you can use these handles to wrap around barbells and dumbells.
Their main job is to make the bar harder to hold onto, which can be a good thing.
(Fat Gripz is one popular brand, but it’s often used as a name for the whole category of object. There are multiple sizes of Fat Gripz, plus other brands, like Alpha grips.)
But what are they really for? They are for when you want to give your gripping muscles an extra challenge.

It’s harder to grip something wide than something narrow. If you’re lifting a normal sized barbell or dumbbell, your fingers and thumb wrap around it. But if you’re lifting something bigger, you need to squeeze with your hand just to be able to hold on. That requires your hand and forearm muscles to work harder.
I believe I can handle lifting them up… Without the dumbbells, of course.
