I love swimming, its one of my favorite activities. Do you swim? 
Yes, I mostly swim for exercise and recreation.
Most people do it purely for recreation, I myself just try to swim for fun while at the same time getting a good workout. 
Same, I like exercising through coordinated movement of the limbs in water.
Being coordinated in swimming can really help you be a professional swimmer I hear, Do you know of any Olympic swimmers? 
Yes, I do. Have you heard of Neil Brooks. He is a sprint freestyle swimmer that won the 4 × 100 m medley relay at the 1980 Olympics in Moscow  
I have never heard of him but he sounds like he was a very good swimmer. 
Yes, another good swimmer is Michael Phelps. He has won 28 Olympic medals in swimming competitions, but he's retired now.
