## Step 1<br />The problem is a fill-in-the-blank type question, which requires us to choose the most appropriate word from the given options to complete the sentence. The sentence is about the basics of setting up a program, which includes starting with single sets and using the correct weight amount.<br /><br />## Step 2<br />The sentence is about the process of starting a program, which involves starting with single sets and using the correct weight amount. The word that fits best in this context is 'lowly'. This is because when starting a program, it is generally recommended to start slowly to avoid injury and to gradually increase the intensity and volume of the program.<br /><br />## Step 3<br />The other options 'quickly', 'tomorrow', and 'at night' do not fit in the context of the sentence. 'Quickly' is not suitable because it can lead to injury or burnout. 'Tomorrow' and 'at night' are not suitable because they refer to time, not the manner of starting a program.
