What a strength training log should solve
Sets, reps, and load are the base layer. They tell you what happened, but they do not explain why a session felt strong, flat, or constrained. Recovery and context make the log easier to use later.
A useful strength app should reduce decision fatigue without pretending your body is the same every day. The best pages in this cluster focus on the moment before training: what should change, what should stay, and how to keep progress moving without making every workout a maximal test.
