LiftEngine

What it does

You describe your goals, equipment and training days. A constraint-based solver rules out anything infeasible: recovery windows, equipment you don't own, time limits. A genetic algorithm evaluates the rest against ten training-quality criteria (progressive overload, muscle balance, compound-to-isolation ratio and others) and evolves them toward the best fit. Exercises in each session are ordered by modality so warm-up, main work and cool-down fall in place. Free, no sign-up, six languages.

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
