This is designed to be used on your barbell when doing landmine work, specifically for bent over rows.
If you’re looking for something that will do EXACTLY this, give you a harder grip strength workout when doing landmine rows, then my word this is the best attachment for that! With that being said, I don’t know many people that are sitting there thinking “man, I just wish I had a better grip pump when doing my rows”… lol. I would not recommend this as your starter landmine attachment. This is definitely something to get only if you’re building a full landmine arsenal and want this very specific functionality.
So, if you do decide you want that functionality, is it worth the $65/$70 brand new? Definitely not (in my opinion) unless you just have to have it. I would say this is something to try and find used for ~$30.
