What the heck are these blue, rubbery looking items? I’m glad you asked!
These allow a user to focus on grip strength by putting these on any barbell or dumbbell. You can use these in the home gym, or even bring your own set to a commercial gym and use on the equipment as needed.
So, is this a worthy piece of equipment for your home gym? They are a fair price for the value you get, but not a lot of my customers find these very useful/interesting (myself included). If you are purely working your grip strength, then adding these to some dumbbells and holding them (or maybe doing farmers walks) will definitely do that, but you can accomplish a similar mission by squeezing bumper plates, for example.
I’ve had 3 pairs of these in stock for about 6 months and have only sold one pair, showing me that there is not a lot of interest for these items (at least on the used market in this area). Unless you’ve found yourself thinking “I really wish I had another way to work my grip, nothing I have right now is quite doing what I need it to” then I don’t see these as being valuable for your home gym setup.
