As with nutrition, we're surrounded by constant reminders to keep physical fitness top of mind. This habit is about establishing a routine more than anything else—hitting the elliptical or attending a yoga class on a regular basis is actually a great way to train your brain and make you more stress-resilient. In the wise words of Harvard University's very own Elle Woods, "Exercise gives you endorphins, and endorphins make you happy." These endorphins also have a tendency to "minimize the discomfort of exercise, block the feeling of pain, and are even associated with a feeling of euphoria," according to Kelly McGonigal. Introducing these added benefits into your life via regular exercise can give you a greater sense of self-control.
