The Third Pillar of Mental Fitness | Health and Vitality Dave Barney and Luke Olson explore the third and final pillar of mental fitness: health and vitality. Rather than framing physical health as a fitness trend or lifestyle goal, their conversation grounds it in capacity. Dave and Luke explain how sleep, movement, and nutrition form the physical foundation that makes emotional regulation and clear thinking possible. They reframe things like anxiety, irritability, and low mood not as personal failures, but as signals that your body may be under-supported.

Dave and Luke connect research and lived experience to show how small, consistent changes can dramatically improve mental well-being. They help to reframe sleep and redefine movement as mood regulation and food as fuel for the brain. As the final installment in their pillars of mental fitness, they help to remind listeners that mental fitness isn’t about pushing harder. It’s about building habits that carry us forward with steadiness and care.
