This is a nice addition to the home gym. Although I can do calf raises on a stair or on other items, this provides a nice stable platform that I can move around. This allows me to position myself exactly so I can admire my calves in the mirror while holding a heavy dumbell in one hand and supporting myself with the other hand.

Like others have said, sturdy and very stable, great non-slip top bonded rubber with deep grooves, this thing is built to withstand more than I will lift in my lifetime. It is the perfect tool, simple yet effective

I use the calf block to do standing and seated calf raises mostly. It is a great addition to my home gym. It doesn't move during use and can easily support the weight of any human being.

So much better than any makeshift idea I've come up with. No regrets other than not getting one sooner.

I finally assembled my dream home gym, and this was the final piece. This calf block is over-engineered and I cannot imagine how it could be improved or built better.

If you want something like this to allow you to work calves (and even stretch calves), the calf block serves its purpose perfectly. Like everything IronMaster does, it is super solid, and I can't think of a way for them to improve it based on size, usability, quality and cost.

This is the best calf block in the market. I had been looking around trying to find the calf block with decent quality and decent price. There were not many calf block out there. I found a few in Amazon and it's more expensive than this one. I think I was lucky that I kept on searching and I found this. This calf block is very strong and it looks like it will last very long time. It also seems to stick with the ground very well and not moving. Great stuff.

Definitely worth every penny!

The calf block is heavy and top surface has a good grip keeping it in place, especially when doing seated calf raises and donkey calf raises and works very well.

You can train calves anywhere with this thing. This is the most well built and study calf block I have ever used!
