Think a quick scroll between sets is harmless? Think again. In this episode, we step out of the standard fitness cliches and aim a deeply analytical, academic lens at a physical object that is currently sitting less than three feet away from you: your smartphone. By bridging the gap between rigorous laboratory science and real-world gym floor observation, we unmask the true cost of how your phone could be hurting your workouts and your relationship with your body.
