<human>:  I need some help designing a fitness routine. What are some exercises I should do?
<bot>: Some exercises you could do as part of your fitness routine include working on your core strength with exercises such as crunches and planks, working on your upper body with push-ups and pull-ups, and working on your lower body with squats and lunges. You can also do running and cycling for cardio, as well as adding in any other exercises you find enjoyable.
