Mark Fu has an amusing post. Do you know what those devices are in the photo above? They are sleeves for the bar to hold the weights in and I'd guess 'd one kilo each. They used to in Russia. Mark asks:
Some things have just one function that justifies their existence; an umbrella for instance. Scuba gear is another that comes to mind. Since most of us are weight lifters in one manner or another, we have all run into barbell collars.
They have no other apparent use. Sure, you could use the ones pictured above at the dinner table to hold nice linen napkins, but I doubt any of us would actually do that.
So are we in agreement that barbell collars have only one function?
He then points us to an article here. Now my two observations are:
1. Was the guy so small that he could do that?
2. Did the guy have a brain in the first place?
All lifters have run into the newbie who wanders around like a lost sheep or the guy who spends half his time in front of the mirror, seeing if his biceps have grown any since he did a set of exercises. I've never run into anyone like this though. :)
