Q: How much of a difference is there in size between the fat replica and the muscle replica?
A: There is an 18% difference in volume between the fat and muscle replicas. Please note that the visual impact of 18% is not dramatic.
Q: I used to have fat and muscle replicas that showed a bigger difference. How do I know that yours are accurate?
A: Nasco (the manufacturer of these models) designed these replicas in coordination with the University of Wisconsin. These replicas are renowned for their accuracy and accurate volumes can be proven with any standard volume test, such as a water displacement test.
