What does that even mean? I don't know. And neither do you! But I just went to Home Depot with an idea, spent about 15 bucks and then skipped over to TJ Maxx and dropped another 15 to make myself a split pad so my buddies and I can train our low back and abs without squishing our junk like we are trying to save money on luggage fees.
Watch the video and see what I mean. Back extensions and ab work without dropping a grande on a GHD machine... can i get a "Hell Yeah?!" As usual, i don't think this homemade version is better than the best equipment on the market, but its a great substitute for those people that train in a garage or have limited resources and still want to do the work.
