<2>Why 7 Out of 10 Is the Effort Sweet Spot for Running Workouts
<>It should feel like 7 on an effort scale of 0 to 10. And even if you think that answer is too simple (which you definitely should), the study has some interesting insights about the physiology and psychology of the optimal workout.
<>When it comes to running workouts, finding the right balance between intensity and duration can be a challenge. One study published in the Journal of Strength and Conditioning Research suggests that the optimal effort level for running workouts is 7 out of 10, which is roughly equivalent to a moderate to high-intensity effort.
<>The study, which was conducted by researchers at the University of Colorado Boulder, involved 12 male runners who completed a series of running workouts at different intensity levels. The runners were asked to rate their perceived exertion (RPE) on a scale of 0 to 10 after
