Swimming is harsh The first day of any practice will leave anyone breathless due to how hard we train. Many skills and rules have to be memorized and drilled into our brains so we can successfully win a race. In a way its like track and field but in the water, Think about it. In both you are a team but compete individually for a score and its all about getting your time lower and lower in a endless grind. Some people i have met will give me the excuse that its "To simple to be a sport. " yes the motion of swimming is simple but it is not easy. Its like a marathon. Its strait forward, Just run this far in a low time, But its extremely hard and physically demanding.
