To those who compete, do you shave or wax?

Odd question, I know.

For those of you who compete in a physique sport (bodybuilding, fitness, physique, or even swimming or cossfit) do you take the time to shave regularly or just wax?

Pros vs Cons?

I've been shaving my arms for years now, and I have a tendency to keep short hair on my legs and I've looking for possible simple solutions?

Wax at home? Salon?
