Smart Scale Body Fat vs Caliper Measurements
**Smart scales** estimate body fat via bioimpedance—easy but hydration-sensitive. **Calipers** measure skinfolds—skill-dependent but track trends well when done consistently.
Step by step
1. Track trends not absolutes
Weekly average under same conditions.
2. Hydration control
Weigh after waking for BIA consistency.
3. Cross-check
Waist measurement + photos validate direction.
