People often say there's nothing new under the sun but I would disagree. Case in point, here's a unique training idea from a muscle magazine from about 20 years ago that I have never seen before or since. These "Iron Teardrops" slipped on your barbell just like plates and moved around while you lifted, adding a whole new dimension to standard lifts.
A few years back, I called the number listed on the ad just to see what would happen. A woman answered the phone and told me that yes, it was her brother which came up with the idea for the Iron Tear Drops but he was not home at the moment. She took down my address and said she would send some info but I never did hear from them. Anyone out there ever get to train with these?
