Here’s what Shari had to say after Thursday’s tire drag races:
Why the heck am I always so sore?
One need only get close to a cluster of IC members talking before class starts and you will invariably hear someone groan, “I am so sore from yesterday’s workout.†And everyone in the circle will nod solemnly and knowingly.
When you’re a newbie, Steve and Maya warn you to get some icepacks because you’re going to be sore. So you expect this soreness, called Delayed Onset Muscle Soreness (or DOMS) that is the result of microscopic tearing of muscle fibers during unusual exertion. It’s all part of the normal adaptation process that ultimately leads to greater strength and stamina as your muscles recover and build. But even the most seasoned IC members still get sore. Why does it seem that your muscles will never adapt to the exercises and cease getting sore?

The amount of soreness you feel is directly linked to how much tearing your muscles undergo. The tearing depends on how hard and how long you exercise and what type of exercise you do. Activities that require eccentric contractions generally cause the most soreness. Anytime you lower a weight (including your body), you are performing an eccentric contraction. Are you beginning to get the picture? Almost everything you do at the IC requires eccentric movement.
But there’s another important piece of this puzzle and it’s the reason why someone who has been training regularly at the IC for awhile can still feel like it’s their first week. DOMS diminishes when your muscles adapt to the eccentric motion. In other words, after a million squats, your muscles are built up and therefore don’t tear as much. All of the sudden, your muscles are a bit, well, cocky. They can handle another gazillion squats. They laugh in the face of a gazillion squats, in fact. But at the IC, we mix it up every day. The exercises are different, and the frequency and load varies from circuit to circuit. So, your muscles never get a chance to get smug.
How about you? When was the last time an exercise at the IC sucker-punched your overconfident muscles?
