A 5’10 man is at a healthy weight between 132 and 174 pounds, based on standard BMI guidelines from the National Heart, Lung, and Blood Institute. But that’s a wide range, and your ideal number within it depends on your muscle mass, body fat, age, and how your body actually distributes weight.
The Standard Weight Ranges
BMI divides weight into four categories for someone who is 5’10:
- Underweight: below 132 pounds
- Healthy weight: 132 to 174 pounds
- Overweight: 181 to 216 pounds
- Obese: 222 pounds and above
The gap between 174 and 181 falls right on the border between healthy and overweight, essentially a gray zone where small fluctuations in hydration or a recent meal could tip you either way.
Large population studies suggest the lowest risk of dying from any cause sits in the BMI range of 21 to 25, which translates to roughly 146 to 174 pounds for a 5’10 frame. A major meta-analysis narrowed the sweet spot further, finding the lowest mortality risk at a BMI of 23 to 24, or about 160 to 167 pounds. That doesn’t mean 145 or 175 is dangerous. It means the statistical center of good health outcomes clusters in that middle zone.
Why BMI Doesn’t Tell the Full Story
BMI treats all weight the same. It can’t distinguish between a pound of muscle and a pound of fat, which is why a muscular man who lifts weights regularly might land in the “overweight” category while being perfectly healthy. A 2025 review from the CDC acknowledged this limitation, noting that newer frameworks now recommend combining BMI with at least one other measurement, like waist circumference or waist-to-hip ratio, to get a more accurate picture.
The Fat-Free Mass Index (FFMI) offers one way to account for muscle. For men, an FFMI of 18 to 20 is average and can look great at a lean body fat level. An FFMI of 20 to 22 is above average, the point where people start to notice you work out. Most men can’t naturally push much beyond that range, and there’s little evidence that doing so would cause health problems even if they could.
So if you’re 5’10 and 190 pounds but carry visible muscle with a flat midsection, your BMI of 27 technically reads as overweight. In reality, you’re likely in better metabolic shape than someone at 165 who rarely moves and carries most of their weight around the belly.
Waist Size Matters More Than You Think
Your waist measurement captures something the scale misses: visceral fat, the type packed around your organs that drives up risk for heart disease, type 2 diabetes, and metabolic syndrome. The NHS recommends keeping your waist circumference below half your height. For a 5’10 man (70 inches tall), that means staying under 35 inches at the navel.
This single number is one of the most practical health checks you can do at home. Grab a flexible tape measure, wrap it around your midsection at belly button level, and note the number. If you’re under 35 inches, your abdominal fat is likely in a safe range regardless of what the scale says. If you’re over 35, losing even a few inches from your waist tends to improve blood pressure, blood sugar, and cholesterol more than the same weight lost from your arms or legs.
Body Fat Percentage by Fitness Level
Two men can both weigh 170 pounds at 5’10 and look completely different depending on how much of that weight is fat versus lean tissue. Body fat percentage gives you that breakdown:
- 6 to 13%: Athletic range, typical of competitive athletes and serious gym-goers. Visible muscle definition, especially in the abs.
- 14 to 17%: Fit range. You look healthy and lean, with some muscle definition. This is sustainable long-term for most active men.
- 18 to 24%: Average range. No visible abs, but not necessarily unhealthy. Many men sit here comfortably without strict diet or training.
Above 25%, health risks begin to climb. You don’t need a clinical scan to estimate where you fall. If you can see the outline of your top two abs, you’re likely below 18%. If your waist measurement is creeping above 35 inches, you’re probably above 20% regardless of your scale weight.
How Age Changes the Target
Men naturally lose muscle and gain fat as they age, even if the number on the scale stays the same. A 25-year-old and a 65-year-old can both weigh 170 pounds at 5’10, but the older man typically carries more of that weight as fat and less as muscle. The National Institute on Aging notes that standard BMI calculators only tell part of the story for older adults, and that someone slightly above the “healthy” BMI range may actually be better off than someone at a normal BMI who has lost significant muscle mass.
This is why strength matters more as you age. Maintaining muscle through resistance training keeps your metabolism higher, protects your joints, and reduces fall risk. For men over 50, holding onto muscle is at least as important as hitting a target number on the scale. A 5’10 man in his 60s who weighs 180 with good muscle tone and a waist under 35 inches is in a stronger position health-wise than one who weighs 160 but is sedentary and has lost much of his lean mass.
Finding Your Personal Target
If you’re 5’10 and just want a number to aim for, 155 to 175 pounds is the range where most men will have a healthy BMI, a manageable waist circumference, and decent body composition without extreme dieting or training. That range shifts depending on your build. Broader shoulders and a naturally thicker frame can support more weight; a narrower build will look and feel best at the lower end.
A more useful approach than fixating on a single number is to track three things: your scale weight, your waist circumference, and whether your strength is trending up or down over time. If your weight is 185 but your waist is 33 inches and you’re getting stronger in the gym, you’re in good shape. If your weight is 165 but your waist is 37 inches and you haven’t exercised in years, the scale is giving you false reassurance.
