I read the glossary of terms but it was too vague. When a workout calls for 4x100 25 kick 25 drill, what does that mean? To just kick, are you not using your arms, or are they just out in front of you, by your side? And do you just breathe when you need to? Also, what is drill? The glossary does not explain it, just says it means to focus on a particular part of the stroke????
Thanks to anyone who can clear this up for me!
