Studies show that muscle has a density of about 1.06 g/cm³, while fat is around 0.9 g/cm³. This means that, for the same weight, muscle takes up about 10–15% less space than fat. That’s why a muscle replica and a fat replica of equal weight look different in size.

Our muscle and fat models realistically replicate the true structure and texture of human tissues. Their design closely matches the actual size, color, and feel of real muscle and fat, allowing students and professionals to clearly see and compare the differences in density and texture between them. They can also serve as a visual reminder for health and weight management, helping people better understand the difference between muscle and fat — and stay motivated to maintain a healthy body.
