Every time you enter your daily workout session all weights log by you are automatically update in the history section of the app which means this app will maintain a history of your entire workouts for each day.
This way you can easily realize how much weight and reps (number of sets) you have increased over some time. The reason why we suggest using "medium" or "light" instead of starting with heavyweight is that using lightweight increases the chances that you do all sets successfully without getting injured or straining muscles too much.
Once you feel confident enough to increase weights then it gets tough to keep yourself motivated because at some point you start feeling pain & discomfort while working out.
This is where tracking progress comes in handy because you can monitor your entire workouts and visually see how much weight and reps have increased over time which will encourage you to work harder.
