Jo Kwon is the longest-serving male trainee in JYP Entertainment, having trained for 2567 days; exactly 7 years and 10 days since joining JYP. He was chosen as the last members of Park Jin Young's "99% Challenge Project" along with Sunye of Wonder Girls.[citation needed]
In 2008, he appeared on MNET's Hot blood, a program that showed the intense physical training that 13 male trainees had to go through for the opportunity to debut in either 4-member ballad group or 7-member dance group One Day under JYP Entertainment.[1] After getting through the eliminations, Jo Kwon was given the position of 4-member ballad group's leader.
