The phrase "average initial body" is correct and usable in written English.
It can be used in contexts such as scientific research, health studies, or fitness assessments where you are discussing the typical starting measurements or characteristics of a group.
Example: "The study measured the average initial body weight of participants before the intervention began."
Alternatives: "mean starting body" or "typical initial body".
