We also weight protein by quality and enforce a leucine floor per meal, all inside one optimization problem.https://jsevilleja.org/posts/your-training-week-is-a-constraint-problem/Thu, 21 May 2026 00:00:00 +0000https://jsevilleja.org/posts/your-training-week-is-a-constraint-problem/A fixed template cannot respect your recovery limits, your split and your exercise preferences at once. We show how gostrong encodes the science as a constraint model and lets a solver build the week.https://jsevilleja.org/posts/your-scale-lies-for-four-weeks/Thu, 14 May 2026 00:00:00 +0000https://jsevilleja.org/posts/your-scale-lies-for-four-weeks/A muscle-gain phase ended up prescribing a calorie deficit because the scale read water as growth. Here is how we caught it, why a 14-day weight slope is too noisy to act on, and the two fixes that now protect every phase.https://jsevilleja.org/posts/meet-gostrong/Tue, 12 May 2026 00:00:00 +0000https://jsevilleja.org/posts/meet-gostrong/gostrong is a training and nutrition app whose plans come from a constraint solver and whose constants each trace back to a published source. This post walks through the idea and what a week with the app looks like.https://jsevilleja.org/posts/stop-the-set-when-the-bar-slows-down/Mon, 04 May 2026 00:00:00 +0000https://jsevilleja.org/posts/stop-the-set-when-the-bar-slows-down/Reps in reserve is a useful idea but a noisy number. On the lifts a bar-velocity encoder can measure, gostrong ends the set when the bar slows by a set percentage, and it keeps RIR as a companion rather than a replacement.
