Fitness starts with a solid core. Just ask Bicycle magazine's Selene Yeager. The "Fit Chick" columnist is an American Council on Exercise certified trainer, the author of "Ride Your Way Lean," and incredibly active by most standards. However, like many of us, Yeager also spends considerable time behind a desk.
Putting in a full day at the office can make it hard to find the time to exercise. But most of us have a bit of a lag between tasks as we sit in front of our computers, and we can take advantage of a few minutes here and a few minutes there to get some physical activity in.
