Understanding Segmental Analysis on Your Evolt 360 Results

What Is Segmental Analysis?

Segmental Analysis is a body composition metric that breaks the body down into specific regions to show how lean mass (muscle) and fat mass are distributed. Instead of looking only at total body weight or body fat percentage, this analysis examines:

• Upper body vs lower body
• Left side vs right side

This provides a more detailed and meaningful view of body composition and how different areas of the body may be changing over time.

What Does “Balanced” or “Unbalanced” Mean?

When the report shows an imbalance, it simply means there is a measurable difference in muscle or fat distribution between regions of the body. This difference is detected by the Evolt 360 system and its analysis method.

An imbalance does not mean something is wrong, unhealthy, or abnormal.

In most cases, these differences reflect:

• How someone trains (for example, more upper‑body or lower‑body exercises)
• How they move and work day‑to‑day
• Sport or activity preferences
• Natural body structure and genetics

Segmental Analysis is descriptive rather than judgement‑based — it highlights how the body is currently distributed, not whether it is “good” or “bad.”

Upper Body vs Lower Body Differences

Differences between upper and lower body muscle or fat levels are very common. Many people naturally develop one region more than another based on lifestyle or training focus.

For example:

• Resistance training that prioritises upper‑body movements
• Endurance sports that heavily involve the legs
• Occupations or daily habits that favour certain muscle groups

From an exercise science perspective, muscles adapt specifically to how they are used. This means regional differences are an expected and normal outcome of consistent movement and training patterns.

Left vs Right Side Differences

Left‑to‑right differences typically reflect natural side dominance. Most people favour one side of the body more when lifting, carrying, stepping, or performing daily tasks.

These asymmetries are common and usually not noticeable or problematic. However, tracking left and right distribution can be useful for:

• Identifying muscle dominance
• Guiding more balanced or unilateral training (single‑arm or single‑leg exercises)
• Supporting long‑term movement quality and strength balance goals

Why Tracking Over Time Matters

Segmental changes in muscle and fat occur gradually. Meaningful adaptations typically require weeks to months of consistent training, nutrition, and recovery.

For this reason, Segmental Analysis is most valuable when used as:

• A long‑term tracking tool
• A way to observe trends across multiple scans
• A guide for adjusting training focus if desired

Single scans provide insight, but patterns over time provide understanding.

Key Takeaway

Segmental Analysis helps paint a clearer picture of how the body is composed and changing. When an imbalance appears, it simply reflects a measurable difference — not a problem or diagnosis.

The most important factors are:

• Consistency in healthy habits
• Monitoring progress over time
• Using the data as guidance, not judgement

When viewed this way, Segmental Analysis becomes a powerful tool for understanding and supporting long‑term body composition progress.
