What calculators do you offer?

We provide a comprehensive suite of fitness calculators designed for strength training enthusiasts:

How accurate are our fitness calculators?

Our strength training calculators use scientifically validated formulas and research-backed methodologies. The One-Rep Max Calculator employs multiple proven formulas (Brzycki, Epley, Lander), while our Wilks Score Calculator uses the official IPF coefficients. Results provide reliable estimates for training planning, though individual variation exists. Use these tools as guidance for progressive overload and program design.

Which calculator should I use first?

For strength training beginners, start with our Strength Level Calculator to assess your current fitness level. Then use the One-Rep Max Calculator to establish training loads. Powerlifters should focus on the Powerlifting Calculator and Wilks Score Calculator for competition preparation.

⚙️ Technical Information & Usage

Our tools supplement professional advice but never replace it.
