Marlene Mauk is part of a growing number of commuters who start their drive to work before most people get out of bed. Instead of sitting at her desk, Marlene heads to a gym near her office.
In 2006, the U.S. Census Bureau reported three million more workers left home between 5 and 6:30 a.m. than they did in 2000, and many fitness centers are opening earlier to accommodate the trend.
Commuters also say an early morning workout also helps reduce their workplace stress.
