It can be useful whatever your fitness goals that you keep, some sort of workout journal or log. It is common for many people to go to the gym with no clear focus and to be frank not really achieving very much.
Following a programme and logging your workouts can help you keep focused and on track. Imagine your journal like a road map. It's going to help show you the route, keep you from side tracking and help keep you focused.
.It doesn't have to be fancy. You could use a simple note pad, use the programme cards at the gym or now you can track it in your phone, tablet or IPad, there are even apps you can use now. Log and keep a written record of reps, weight, rest period and tempo for each set done. .
You could use your journal to log your distance, time or route. If you wanted it could be a record of the duration and type of any workout, along with the days and frequency of each routine. If you wanted to be more specific you can log what you ate and drank.
The best indicator of a quality workout is goal achievement, not as many seem to believe that its about how sore or sweaty you are. Each session you should look to improve on the last and when you look back, you notice your progress. You should be able to see how depending on your goals that you can now lift more weight, have gotten stronger or can run, cycle much faster/longer etc.
When you see your achievements it can also be quite a confidence booster.
