The Gym Progress Calculator helps you track improvements in your strength and performance by comparing your initial and current lifting data. It estimates your one-repetition maximum (1RM) using the Epley formula and calculates both total and weekly percentage progress over your training period. By entering your exercise name, initial and current weights, repetitions, and training duration, this tool provides a clear picture of how much stronger you’ve become. It’s a practical way to evaluate the effectiveness of your training program, identify areas for improvement, and stay motivated to reach new fitness goals while maintaining consistency and proper recovery.
