About Us

CaptainCalc started in a garage gym with a whiteboard covered in scribbled percentages. I'm a strength coach who spent years watching lifters — myself included — waste effort because the numbers behind their training were fuzzy. People would guess their max, round their macros to something convenient, and load the bar wrong on a heavy day. The training was hard; the math was lazy. This site is my attempt to fix the second half of that problem.

The mission here is narrow on purpose. There are plenty of general wellness sites that will tell a beginner to walk more and drink water. That is fine, but it is not this. CaptainCalc is for people who already lift with intent — hypertrophy trainees, powerlifters, physique athletes — and who want their one-rep max, their fat-free mass index, their plate loading and their macro splits calculated properly rather than eyeballed. Every tool was chosen because I have needed it myself between sets or while programming a client's next block.

I build each calculator around formulas that have earned their place: Epley, Brzycki and Lombardi for strength estimates, the US Navy method for body composition, and standard evidence-based approaches for protein and progressive overload. Where methods disagree, I show you the disagreement instead of hiding it, because a lifter who understands why two numbers differ makes smarter decisions than one handed a single false certainty. The goal is never to replace your judgment — it is to give that judgment better inputs.

The blog exists to go a level deeper than any calculator can, unpacking where these formulas come from and where they quietly break down, so you know when to trust a result and when to take it with a pinch of chalk. If you spot an error, want a tool that isn't here yet, or just want to argue about rep ranges, reach out at [email protected]. I read everything, and this site gets better because lifters tell me what they actually need under the bar.
