How do you feel about before and after pics?

When I first started out, I tried to use them but came up against a lot of resistance from clients(some people don’t even like getting weighed or measured). Although they are sometimes powerful marketing tools, the client’s wishes come first in terms of what they are comfortable with. I find that clients are much more agreeable to testimonials, to the point where most of them allow their first and last names to be used(not just initials that you see all the time.)
