Lifting weights<br>I went to go work out the other night. The gym was not very busy at all. I got to use all my favorite machines without waiting. I think I'll go at the same time tomorrow. I get a lot more done at the gym when it is not busy.
The gym will not be busy if I go at the same time tomorrow.
The narrator is assuming the gym won't be busy at the same time. It might be busy, it might not.
