Swimming, like many sports has its own vocabulary and acronyms that can make reading a work out a mystery. Understanding the sports terms is often necessary to look at a workout and understand what you are supposed to do. I am often asked what is ‘drill’? Or what does P/K/S mean? To help out I have compiled a glossary of the most common terms and acronyms used by coaches, swimmers and officials. Have a term I have not included in the attached glossary? Post it below and I will define it for you and add it to the glossary. Download or view the PDF Glossary of swimming terms.
