<qa>  What is the name of the treatment approaches that are hypothesized to result in improved daily activityThere are few studies that demonstrate how to best improve daily activity in people with heart failure HF. Exercise alone has been shown to be ineffective, but other techniques such as daily activity feedback with encouragement or health coaching may be helpful. This research study will investigate two different treatment approaches for improving daily activity: 1 daily activity feedback and encouragement, and 2 health coaching with an individualized home exercise program. Both treatment approaches are hypothesized to result in improved daily activity compared to a control group.
