To prevent cramps, eat bananas because there is a lot of potassium in them, also drink plenty of water. But also don't worry about what other people think about you. It's not worth it to go through classes that are actually really fun when you just enjoy yourself and have to worry about those immature kids in your school.

You kind of have to figure that out yourself. It is different for everyone. You need to find out how much water and food to drink before and after exercise to prevent cramps. Too much and you'll get a cramp, too little and you'll get a cramp. Experiment with it and you'll soon find out. Good luck and God bless you.
