if cheer is what you want to do then do it. practice practice practice. cheerleading isn't just about flexibility. (although it definitly helps with tumbling jumps dance and stunts) it's about being positive and showing school spirit.
some cardio and basic stretches will help with athleticness
Try it out and practice before you try to join!
You can become more flexible by practicing a bit of the basic moves every day.
Try yoga too!
You can do it if you put your mind to it. Try out because you never know what may happen.
Sometimes, you don't need to be flexible! If you weighted 90 lbs, you would be a flyer, so you would need, but since you'll be a base, you really don't need to be that flexible!
So try out and you'll see that you will LOOOOOVE cheerleading
I think you should at least try out. my cousin started cheerleading when she was 14 and she wasnt flexible at all and she only played soccor. Also i think you will be perfect for cheerleading! i hope this helps! Good luck!! :) :)
you should go for it! your weight doesn't matter and as long as you have sharp moves in cheers and are loud you should be fine.
