Contact Us
Questions about a calculation, a bug to report, or just want to talk training? Here’s how to reach us.
Email Us Directly
The fastest way to reach us is by email. Whether it’s a question about how the 1RM calculator works, a suggestion, or something that looks off in your results, send it over and we’ll get back to you personally.
onerepmaxcalculatorz@gmail.comFound a Bug or Wrong Calculation?
If a result looks off, tell us exactly what you entered — the weight, reps, RIR, and which formula you used — so we can actually reproduce it on our end instead of guessing. This kind of detail is what helps us fix things fast.
Feature Requests & Feedback
Want a specific lift added, a different unit option, or a feature you’ve seen elsewhere and wished this calculator had too? We read every suggestion, and a good chunk of what’s already on this site started as an email just like that.
Partnerships & Collaboration
If you’re a coach, gym, or fitness content creator interested in collaborating or linking up with this tool, reach out and let’s talk.
We typically reply within 24–48 hours. This is a small, independently run project, so thank you for your patience if it takes a little longer during busy periods.
