Im 12 and want to try tumbling?

Its according to where you live but there should be more than one cheer gym. Search around for a cheer gym close to you that offers the times you need. You are definately not to young i am 19 and still taking classes. You will love it and the only tihng you need to do at home is practice your splits and bending backwards. Try flipping off the arm of the couch backwards. GOOD LUCK!
