Body composition from a photo (more than just a number)

“Body composition” is basically the relationship between fat + muscle + proportions—and the decisions you make because of it.

If what you really want is photo-based physique intelligence, this page is the bridge between a simple check-in and a smarter next move.

LeanLens is designed to give you useful context from your photos:

• a confidence-aware body fat range
• strengths and focus areas
• training and nutrition guidance you can use this week

Body composition ≠ only body fat

Two people can be the same weight (or even similar body fat) and look totally different because of:

• where they carry fat
• muscle development (shoulders, back, legs, glutes)
• posture and proportions

So the goal isn’t to chase a single number. It’s to get clarity on what to improve next.

What LeanLens shows beyond the % estimate

LeanLens surfaces:

• Strengths: what already looks good (keep it).
• Focus areas: where small improvements can create noticeable visual payoff.
• Physique profile (when available): a quick read on your frame and development balance.

Turning insights into training priorities (without restarting your whole program)

Here’s the move that works for most people:

1. Keep your main lifts the same.
2. Add 2–4 hard sets per week for a focus area.
3. Keep that for 4–6 weeks, then re-check in.

LeanLens is meant to help you simplify the plan, not add complexity.
