My sister is on the path to be recruited for gymnastics. She has been involved in the sport since she was one year old and is now at the highest level of her sport. She has been competitive for over 10 years and has won many, many competitions. She spends 40 hours a week at practice, does online schooling, and participates in competitions all around the country.
Unless you have a lot of background in a sport/extremely talented, you will not get recruited for a sport. Choose your ECs because you enjoy them!
