Shoulder-to-waist ratio

How to measure consistently

• Shoulders: measure around the widest point across shoulders (not chest). Keep the tape level and snug, not tight.
• Waist: navel-level or narrowest waist both work—pick one standard and keep it consistent, or your trend gets noisy.
• Repeat 2–3 times and average; log date and context (training/diet) for better comparisons.
• Measuring guide (includes straight-line shoulder width)
