❓ WHR FAQs
What should my WHR be? WHO guidelines: 0.90 or less for men, 0.85 or less for women. Above 1.0 (men) or 0.85 (women) signals substantially increased health risk.
Can I lower my waist-to-hip ratio? Yes — regular cardio, strength training and a modest calorie deficit shrink waist fat first, which is exactly where WHR improves.
