1RM Calculator & Program Generator
How This Helps You
This tool estimates your one-rep max using proven formulas, so you don't have to test your absolute limits in the gym. Enter any weight you've lifted and how many reps you did, and it calculates what you could theoretically lift for a single rep. It uses multiple formulas and averages them for accuracy.
But it goes beyond just numbers. You get a complete breakdown of what you should be able to lift for different rep ranges, plus percentage charts for programming. The real value is the automatic 4-week progression program it creates. Whether you want to focus on strength, power, or muscle building, it gives you a structured plan with specific weights, sets, and reps for each week. This takes the guesswork out of progression and helps you train smarter, not just harder.
