Progressions bug in Tj Barbell Gain

I received a response from support regarding this issue. The answer is as follows and I hope it will be useful.

"Here is an explanation on how the logic for weight training works depending on your feedback, and especially when you reduce the weight or reps in a barbell interval.
The underlying assumption is that such adjustments are made because you were unable to perform the original assignment. This could be due to hitting muscular failure, resulting in reduced reps, or anticipating that you might reach muscular failure and therefore reducing the weight.

It’s important to note that the first instance of failure in an interval is crucial. Regardless of what happens afterward, it is this initial instance of failure that determines the estimation of your capabilities for the next session.

In your specific case, you reduced the weight from 32.5kg to 32kg in the second warmup set. This warmup set was intended to be at 55% of your one-repetition maximum (1RM), meaning we estimated 32.5kg to be 55% of your 1RM. However, since it triggered the assumption of failure, we subsequently estimate that 32kg represents a much higher percentage of your 1RM. This estimation led to the significant weight drop in the subsequent interval that you described.

While there could be various reasons for lowering an assigned weight besides hitting failure, such as not having specific weight plates available or simply wanting to simplify the loading process, it was decided during the development of the user experience that separately asking you if you hit failure on each set would be too burdensome in terms of user interface complexity. Therefore, the logic described above was adopted.

I hope that helps you to understand a bit better the logic applied and also the limit that can happen during weight training via our app.
