A doctor renews an old passion and restores his health.

During his medical residency, Dr. Langston Powell gained 20 pounds. Something was missing from his life: his bike. For years he rode it everywhere, but now a car seemed more convenient. As a physician, he knew he had to make a change.

“Though we have made great strides in the treatment of heart disease and cancer, we are losing the war on obesity,” Powell says.

He now rides his bike almost daily, sometimes covering 100 miles a day. He makes the most of his exercise time, and the results are evident. He’s lost the weight and reduced his body fat to 10 percent.
