Understanding Body Composition Analysis

Your scale weight tells you almost nothing useful.
What actually matters? How much of you is muscle versus fat.
Our AI breaks down 18 muscle groups across your body.
Some areas might be strong and developed. Others? They're hiding, underdeveloped, waiting for you to target them.
Your chest, shoulders, back, and legs—these are what build your foundation.
Develop them right and you get width, depth, proportions that look balanced and athletic.
This analysis shows you where you stand right now and what needs work.
