Resistance- the refusal to accept or comply with something; the attempt to prevent something by action or argument.
A few common examples of resistance in horses:
Getting behind the bit
Running through the bit
Dropping the shoulder
High or tossing head
Gaping or busy mouth
Tipping the nose to the outside
Pushing out against the reins
Resistance is direct result of:
Lack of Training
Now you must be asking yourself why I'm talking about resistance in the middle of a biting discussion, because we as riders often use bits to fix resistance, and that the more resistant a horse is the harsher is bit that should be used.
(yes that is a bike chain bit, these are from our evil bit collection)
Bits can create resistance through poor fit, pain (from the bit or from needing dental work), fear,and lack of training.
Good bits can wear out and cause resistance.

Pain, poor fit, and lack of training create resistance undersaddle, and a harsher bit should only be used after all other aspects have been explored.
A bit is never a subsutite for training.
