The answer to this question is #2
Answer:
It's super important to warm up before exercise. Without warming up before exercise, you can seriously hurt your body. You might pull a muscle, trip, and many other things that can do damage to your body. Starting right away at some sports or exercise without warming and having your body prepare for the amount hard work you're going to do will harm your body.
Hope this helps!
