 Dana said, remember, you should mix up your routine because your body naturally adapts to repetitive movements, and that leads to diminished returns. Think of SMART goals, specific, measurable, achievable, relevant, and time-bound, meaning by what date you're going to achieve it. Track your progress, big and small, she says, so you don't lose sight of how far you've come or overlook impressive milestones that you're just not realizing.
