Head Grown-Up of Grown-Up Swimming Brian Robbins drops in on the SwimSwam podcast to breakdown the swim-fun-movement sweeping the nation. Grown-Up Swimming started in Atlanta, GA with a group of teams that wanted to have as much fun swimming as their kids have in summer league. That movement has grown-up (not apologizing for that pun) to provide a low-pressure, high-fun swimming environment for hundreds of people of all ages and abilities. Literally: start swimming for the first time since college or high school, swim competitively for the first time ever, or take a break from your 6,000 yard Masters workouts to have some fun.
