Another comic for the week! Yogurt is teaching Berry how to swim in this comic.
Leg cramps are surprisingly common for both beginner and trained swimmers. Doing stretches before you start swimming helps a bit, but you can still get cramps when you are not careful. Sometimes it has more to do with deficiencies in the body. Either way, getting a leg cramp as you are swimming is one of the worst pains I can imagine when I’m at the pool.
