Core attachment

The Core attachment for the Modular system is the piece that brings all the attachments together and offers a whole new dimention in training.  Slide this on to a barbell end and use it in the leverage Core position to make ALL the Modular Plug Ins a whole different beast.  This is one of my favorites.  I've been using the prototype for quite a while and finally have made it available to you.  I promise it will open a plethora of new exercises and angles to work with.

    This is beautiful

    Posted by Michael on 5th May 2017

    Mine was built to convert to standard or Olympic. Have only used briefly to test but it is just beautiful. Fits both my cheaper mass produced made in China standard bars, and my much nicer Ivanhoe B86 bar, if anyone is interested. Going to get a lot of use out of this. Have already ordered a second one.

    I ALSO did not know I needed this!

    I just saw a review of this attachement and like the previous chap I was fully happy with my life and existence until Ryan mentioned that he had just "invented" this and perhaps I should check it out. Like the previous chap I had a Gut Wrench but it was limited because of how the end of the bar could be gripped but with this coupler Ryan has opened up a huge new arena of strength routines that I can do with or alternate with my Modular Grip System or with the Plateau Buster. Personally I have found the best approach is to use my new GripMo Ball which Ryan crafted to accomodate both a chinning bar AND the angled bar training and I am looking forward to getting the thick axle to improve even more. This seems like a simple connector but it is in fact a gateway to great strength.

    Did not realize I need it until Ryan built it!

    I have the modular grip system and gut wrench. Using the gut wrench is a taxing workout, but there is limited ways to hold the end. This core attachment helps solve that problem because I can now use any of the modular plug-ins on the other end of my barbell and get a great workout. I am now waiting for Ryan to send me my thickburger grip axle so that I can use it with this!
