Love having this in my gym, is great for grip strength and people love trying it out when they pop in my gym. One of my favorite grip trainers, they are rarely in stock!

I bought this as I have been working my way up a stack of blobs. Surprisingly hard to lift, I have pretty average sized hands and the challenge isn't necessarily just the weight of this thing but that is the size of a half hundred blob and it's just plain hard to get a grip

Five stars from me. It’s a really tough lift. I’ve never done a fifty pound blob before and I didn’t realize how hard it was to grip the thing. Steadily working my way to it.

This blob trainer is really cool. I have average size hands and just using the unloaded trainer is a challenge. Definitely one of the coolest pieces in my gym

Great way to train blobs. Built as a half 100 so it's on the thicker side making it more challenging.
