Adam Dunn of the Chicago White Sox, Brad Penny of the Detroit Tigers and Russell Martin of the Yankees have used the sport’s punches and kicks to improve their throwing and swinging. In addition to improving overall fitness, Martin said, mixed martial arts can make an athlete mentally tougher.
“You tolerate the pain and get through it,” he said. “Mentally, I know I’m in a good place because I worked hard.”
Unlike Martin, Dunn and Penny guard the secrets of their workouts as if they were team signs.
Penny acknowledged training with Dan Henderson, but he declined through a Tigers spokesman to discuss his training. Dunn declined through the White Sox media-relations office.
