Have you ever wondered why it is so darn difficult to pry yourself off the couch and exercise? Well you may be able to blame it on mom and dad.

According to Psychology Today:

"Dopamine is a neurotransmitter that helps control the brain's reward and pleasure centers. Dopamine also helps regulate movement and emotional responses, and it enables us not only to see rewards, but to take action to move toward them."
