Dave sends me an e-mail with the exercise picture. 99% of the time, I know what the exercise is. Even if it's strange, I can usually figure it out. This is because I grew up in the weight room-era that forced critical thinking and a "necessity breeds invention" way of exercising. There were very few books and no internet to guide you along.
But Dave sent me this picture entitiled Zig Zags. Now the first thing I think when I hear the term "Zig Zag" is rolling papers for burning a twister. Not a bad past time, but since I may run for political office someday, I'm not going to admit to anything. But if you are looking to get a little stupid by all means - don't bogart the joint and keep passing it around.
So what Dave meant by Zig Zag - your guess is as good as mine. Perhaps after doing multiple sets of 20 of this particular exercise your head feels as if you've gone through a few Zig Zags. Or maybe Dave's was partaking and it was a typo. If he is, I'm a little disappointed in his selfishness.
