The Fitness Mindset: Eat for energy, Train for tension, Manage your mindset, Reap the results

Many fitness books focus on workouts and diet, but this one emphasizes mental habits. I'm curious what motivated that approach.

Some of the mental strategies felt simple in theory but harder to apply consistently. Has anyone found effective ways to stay motivated long-term?

With so much advice out there, it’s interesting to see which principles made the cut. I wonder what led to the selection of specific tactics.
