Final answer:
A warm-up should be similar to the exercise you are going to perform, but at a reduced pace.
Step-by-step explanation:
A warm-up should be similar to the exercise you are going to perform, but at a reduced pace. This means that you should perform movements or exercises similar to the ones you will be doing during the main exercise, but at a slower and less intense level. For example, if you are going to run, you could start with a slower jog or brisk walk as a warm-up.
