<human>:  What's the best way to safely increase my rate of physical activity without risking injury?
<bot>: The best way to safely increase your rate of physical activity without risking injury is to start with low-intensity activities, like walking or light jogging, and gradually increase the intensity as you become more accustomed to the activity. Make sure to stretch before and after exercising and to listen to your body for signs of pain or fatigue. Rest when needed, and do not overexert yourself. Find a trainer who can help you make a plan that satisfies your fitness needs and goals.
