Subjects will also be dispensed a pedometer and encouraged to wear it daily for the first 2 weeks of their study enrollment in order to establish an average baseline number of steps per day. Thereafter they will be instructed to wear the pedometer 3 times per week and to chart the number of steps taken between waking and retiring to bed and encouraged to 'make up' for days/weeks when fewer steps are taken due to increased symptom burden, post-chemotherapy fatigue, or other contingency.
