The third NorCal city to break the top 10, San Jose shares many of the same attributes that landed San Fran and Sacramento on the list – great parks, plenty of rec centers, and loads of healthy, fresh foods at residents' fingertips. You can't beat San Jose's weather for working out year-round, so it's no surprise that people that live there are trim, toned, tan, and happy.
