Jimmy John's Sports Corner: Tae Kwan Do

Yvonne St. Croix and Tre' Powlis are training in Traverse City for the ATA World Championships

Mastering the art of Tae Kwan Do can take years to perfect.

12-year-old Tre' Powlis and 7-year-old Yvonne St. Croix of Traverse City are advancing so fast in the sport that they will be appearing at the ATA World Championships July 9th-14th in Little Rock, Arkansas.

7&4 caught up with both of them and Master Chris Pline of ATA Martial Arts in this week's Jimmy John's Sports Corner.
