Are you being serious? Athletes at the highest level are the same as Professional Dancers [I was one] or professional footballers or other top athletes. The training takes around ten years and usually starts around the age of 6,7,8 or 9. By the time they are in their early teens most , if they are serious are training all day Saturday [for around 6 hours] and around four or five evenings a week for around three hours a night. All holidays spent at summer training schools, intensives, private coaching,etc. And even then there are so many hundreds and hundreds of young people all doing exactly the same thing to that level of intensity there is no guarantee of success. Very few make it. If you are already 22 years of age you should be just about now be coming to the peak of your career, not just starting out. Unless you were outstandingly gifted and had natural ability. But people like that are incredibly incredibly rare. I trained in Classical Ballet for eight and a half years from the age of nine. Many others started at six. By the time they were eleven 24 children [12 boys and 12 girls] were at the Royal Ballet School . Over 3,000 children audition each year for one of those 24 places. IF they are truly brilliant they will make it all the way through their 8 years of training at the Royal Ballet School. Usually about 10 make it through to the final year. Of those 10 maybe 3 or 4 are accepted into the Royal Ballet Company. Then most of them will never get out of the Corps De Ballet [the chorus]. Being an Olympic Athlete is equivalent to dancing for the Royal Ballet or a Premier League club.
