Now that the 4th of July has passed, it feels like summer is really in effect. It hits in the upper 80s every day, stays light until 9:00, and every public building is freezing because the air conditioners are all on full blast. It’s the best time of year to focus on your health, too: the weather in conducive to swimming and outdoor workouts, and the grocery stores are bursting with yummy fresh produce. I’ve been working out with a trainer once a week, and I’ve been trying to squeeze in a few workouts on my own between sessions, so I thought I’d share my 2008 summer exercise playlist.
