Maximum Weight Calculator
Know Your Numbers. Train With Purpose.
The BASED Max Weight Calculator gives you a fast, accurate estimate of your true 1RM & MW using the Epley formula.
Just enter the weight you lifted and how many clean reps you performed. We'll calculate:
- Your estimated 1-rep max
- Your MW (Maximum Weight)
- Smart working sets from 85% down to 40%
- Suggested reps for each percentage — perfect for warm-ups, top sets, and building volume
Why It Matters
Your training should be based on reality — not ego. Knowing your MW helps you:
- Program lifts with precision
- Apply progressive overload intelligently
- Train harder, recover smarter, and avoid burnout
Every BASED protocol is built around these numbers — the file calibrates your working weights from your real strength. This tool gives you that number in seconds.
