Hi everyone, I am the maker of PeakLoads. As someone deeply involved in strength sports and constantly analyzing training programming for podcast discussions, I noticed a persistent friction in how we calculate our daily lifts. Spreadsheets are incredibly clunky on mobile devices during a workout, and most existing fitness apps overcomplicate simple barbell math. I wanted a fast, clean command center for my own training sessions, so I built PeakLoads. It solves the tedious parts of strength programming. Whether you need to quickly estimate your 1RM using reliable formulas like Epley or Brzycki, generate working weight percentages, translate your RIR (Reps in Reserve) to gauge fatigue, or plan your specific activation sets for the big three lifts, it is all accessible instantly from the gym floor. I focused on making it a lightweight, responsive web app with absolutely no bloat just the precision tools that strength athletes and coaches actually need. I would love to hear your feedback, especially on the RIR Translator and the advanced warm up sequencing features. Let me know what you think!
