What need to my excess fat percentage for my arms, legs and trunk be? I just obtained a scale that may not just give me my excess fat proportion for my whole system, but could also break it down to provide me my fat percentage on my human body components (for example: Arms with 42% of extra fat, legs with 30% etc.) Nevertheless, it doesn't inform me what the norm should be. Could anyone tell me what is the regular excess fat percentage for arms, legs and trunk will need to be? Thank you really a lot.
