Like an elite athlet
Im sure if this is what you want that it is not something you plan to start next year, im sure there are junior compettitions and that athletes just dont walk in de novo at age 22 and say im ready to do this.
Thus if you are seriuos you likley have tried it at some level. Any physical competitive sport needs medical exam and clearance whether it is your leg or heart
, you need talk to your own doc!
