Holding those potato chips

Another week, another Yasso. I'm at the Brunswick Middle School track for my weekly Yasso interval workout. It's intense and tedious in equal measure. But early on, I remember some coaching advice (given to U.S. Olympians) that I heard a long time ago.

When running a hard workout, give it the full 90%. That's 90% of your total effort. You heard that right: 90, not 100. You should do this for 90% of the distance. Only in the last 10% should you ramp up your speed to 100%. The time, distance, effort percentages, and everything else about this advice is, of course, relative and subjective. For intervals, you can apply the principle to each repeat, and/or to the workout as a whole. It's more of an attitude, a way of thinking, than anything else. Something to tell yourself during the workout. This kind of self-talk is pretty critical.

Whilst giving it that full 90%, you need to keep yourself under control. You need to relax. This is another critical mindset. To go along with the relaxation self-talk (like, 'fast, yet easy-does-it'), you should consciously relax your body, mostly your face. Yes, shoulders, legs, and other parts of your torso, but concentrate on your face. Eyelids at half-mast, and relax your mouth. Maybe even smile a little. Don't make a crazy face like I've been known to do. If you do want to do that, wait until the last 10% of the distance, when you're about to give it 100% effort. Then and only then, go ahead and grimace.

One more thing: when you're relaxing your body and face, pretend you're holding a potato chip in each hand, between your thumb and first two fingers. Hold it gently, and don't crush it. This will help you stay in relaxation mode.

Today, I apply these principles to each repeat 800, and guess what? It works.
