Ladies who have been pregnant (and male counterparts of ladies who have been pregnant, and friends of ladies who have been pregnant, and people who have read about pregnancy) know that making it through 40 weeks of pregnancy without stretch marks is something to brag about. But not something to brag about **too** loudly, lest you become one of "those women."
So I've been doing these speedwork exercises as part of the "Run Less, Run Faster" program that I'm following (I'm sure that will be its own post later on), and, as "speedwork" would imply, there's a lot of short distance sprinting at a pace much faster that I'm used to. Sprinting uses and builds muscles differently from running longer distances at a slower pace, so I've suddenly got some nice upper leg muscles going on. Based on this random leg muscle diagram, it appears to be my Tensor Fasciae Latae and my Rectus Femoris that are benefiting most (or maybe not, I'm not an anatomy and physiology expert. whatever happened to quads and hamstrings?).
Great, huh? Well, yes, until I spotted a small web of stretch marks a few inches below my hipbone, right on the spot where that "Tensor Fasciae Latae" supposedly is.
WTF? Exercising is supposed to make you look better, not give you stretchmarks!
