1. When you first start up, you will be prompted to set what to record on the "Recording item screen".
For those who find it difficult, you can load a sample of the item, load it, modify it, and save it.
2. After that, all you have to do is record your exercise performance. I think it's best to record every day, but it doesn't matter if you record multiple times a day or if there are not every day.
3. You can set a target value for the record item, and when the actual value exceeds it, a "well done mark" is displayed.
4. The recorded data can be displayed as a bar graph up to the last 14 times.
