What is the Lean Gain Calculator?

The Lean Gain Calculator helps users measure how much lean muscle mass they have gained over time by comparing starting and current body measurements. By entering body weight and body fat percentage for both the beginning and current stages, the tool calculates lean mass values and determines the percentage increase or decrease. This makes it easy to track muscle-building progress and understand how effective your training and nutrition plan have been in improving lean body mass.

How to Use:

1. Enter Starting Weight: Type your initial body weight before beginning your training program.
2. Enter Starting Body Fat (%): Provide your starting body fat percentage.
3. Enter Current Weight: Enter your present body weight.
4. Enter Current Body Fat (%): Type your current body fat percentage.
5. Click “Calculate”: The calculator computes starting and current lean mass, then evaluates your lean mass gain percentage.
6. Review Result: The output shows lean mass values, percentage gain, your input values, and a motivational message based on your progress.
