It s up to you. If there is a weight requirement, I d seriously reconsider joining the team. Weight is dependent on the body type, and it should not be forced upon anyone. They might also have rules against body piercings, tatoos, odd hair color, long nails, nail polish and more. Still, it s best to be informed before hand so you can be prepared for tryouts.
Some squads do football, basketball or wrestling, soccer and often competitions.
You ll want to know what you are committing to. Most schools make the whole team try out each year, so figure last years members will probably make the team this year. Count off the graduates or those who will make Varsity and that will tell you what your chances are. You ll get the best insight by talking to the other girls on the team. They ll let you know if they like the coach and if practices are too much.
