During the last swim class, coach gave me a few tips and instructing me to think of how to achieve that kind of body alignment that he wants to see. It did take me quite a fair bit of conscious effort to achieve that straight body line, hairline at water surface. Needless to say, it is the most tiring session ever since I started with him. I could feel soreness on my arms. I could feel heat generated out of the body while swimming.

Now, 3 days later.... My arms are still not as fresh. Is that what you call as Delayed OnSet Muscle Soreness (DOMS)???????
