Pinching buds

I've heard people talk about pinching/twisting off the buds on fruit trees so they don't produce that season & thus grow stronger. Is this good practice if one has the time to do it? If so, do you literally just pinch or twist the buds off? Can this be done on Pear, Apple, & Peach trees?

Pulling the flowers off is easier and less likely to cause damage to the bark.
