Breathe in as much as you can and push out from your gut. Make sure it doesn't come from your throat, you'll eff up your vocal chords. What helps for learning this, is drink some type of soda before you do this, sprite works best. Though soda isn't recommended right before vocal work, it's great for practice, because the sugar coats your throat, making it less dangerous, especially when your unsure of how to do it.
