Is 70 kg good for 170 cm

70 kg (approximately 154 pounds) for someone who is 170 cm (5'7") results in a Body Mass Index (BMI) of approximately 24.2, which sits within the "normal weight" category (BMI 18.5-24.9) but near the upper end approaching "overweight" (BMI 25-29.9). Whether this weight is "good" depends entirely on body composition—specifically, the ratio of muscle mass to body fat—rather than the number alone.

For a sedentary person with minimal muscle development, 70 kg at 170 cm might represent a soft physique with higher body fat percentage, potentially indicating room for improvement through strength training and body recomposition. Conversely, for someone athletic or regularly engaging in strength training, 70 kg at 170 cm could indicate a lean, muscular build with low body fat, representing excellent fitness since muscle weighs more than fat tissue by volume. To accurately assess whether 70 kg is optimal for you at 170 cm, consider these factors: how your clothes fit, your waist measurement (waist-to-height ratio under 0.5 is generally healthy), body fat percentage (if measurable), physical capabilities and energy levels, and medical markers like blood pressure, cholesterol, and blood sugar. An athletic person at 70 kg with 15% body fat is in vastly different condition than someone at the same weight with 25% body fat. Rather than obsessing over scale weight, focus on body composition, fitness level, how you feel, and health indicators. If you're 70 kg at 170 cm and have good muscle tone, healthy cardiovascular fitness, and positive health markers, this weight is excellent. If you have excess body fat and poor fitness, the same weight might indicate opportunity for improvement through better nutrition and exercise.
