There are many different terms used to describe positive training techniques: positive reinforcement, reward-based, force-free etc..
What they all have in common is a shared belief that it is much safer, more effective, to teach our dogs using the concept that if you reward a behaviour you like, it is more likely that that behaviour will be repeated. If you redirect a behaviour you do not like, it is more likely that the behaviour will decrease. Combine this with the awareness that dogs are not wolves trying to dominate us, and therefore do not need to be controlled using dominance-based punishment techniques, and you have the recipe for our training beliefs.
I believe that enhancing your relationship with your dog and having fun go hand in hand.
