It's writing the alphabet in the air with my toes. Here's an example that's a little more thorough than what I've been doing:
Please note that I can't endorse all the Red Sox stuff in the background, but this seems like a good example. I've just been writing through the alphabet once or twice several times a day while I'm working or watching TV and before I run. I've been doing a little better with strength training lately, which may be helping, but I've noticed I didn't have any exercises for the muscles on/next to my shins, which is where I have so much trouble on my left leg. This alphabet thing seems like it fills that void in my workout routine.
Now, my quads were another story. My quads felt weak (I blame last night's fencing class for this) throughout the run, I've clearly lost some conditioning over the past month, and it was digustingly humid and warm this morning. A four-mile run (per my training plan) that I wanted to turn into a six-mile run since my shins and ankles felt so great ended up a five-mile run when I felt like I was going to overheat if I went another mile.
And since this post is boring and people come here for the cat pictures, here's Higgy helping me work.
