These tools give you instantly actionable numbers. The 1RM calculator helps you set training intensities based on a percentage of your max. The plate calculator eliminates the mental arithmetic before a heavy lift. The strength standards tool shows where you genuinely sit among other lifters — not just what feels hard. And the split quiz matches your goals, schedule, and experience to a proven program.
All tools support both kg and lbs, and every result links directly to the relevant program or blog post in SteelRep so you can take action immediately.
