A big, two-fisted workout

"My writing is nothing," Ernest Hemingway once opined. "My boxing is everything." He duked it out with a hostile literary critic in his editor's office in New York, and took swings at such literary institutions as John Dos Passos and Ezra Pound. Pull your best Hemingway impersonation and shadowbox with weighted gloves (or holding light dumbells). Start with smooth, controlled punches -- six to the imaginary body, six to the phantom head, and repeat for 30 seconds. Later you can add other punches and combinations to the program. For now, keep those gloves up and feet dancing. Extend the punch out, then pull it back to guard your face and chin. Bob and weave to avoid vicious (if fictitious) counterpunches.
