<human>:  What is a good cardio routine for a beginner?
<bot>: A good cardio routine for a beginner could include activities like jogging, cycling, walking, or swimming. Each of these activities can be done at a low to moderate intensity, allowing a beginner to build up their stamina and endurance over time. It is important to listen to your body and start out relatively slow, gradually building up your intensity as you become more comfortable with the routine. Also, don't forget to take breaks when needed and stay hydrated!
