Exploring Seven: We first brought up RPE (which traditionally means "Rate of Perceived Exertion") all the way back in Episode 2. A quick refresher: when using RPE, you rate your subjective experience on a scale of one to ten. In weight training, we define a seven on that scale as the point at which we can no longer synchronize the breath and the motion. That's also the point at which an exercise switches from pure gains to some level of detriment. RPE is such an important tool that we spent Episodes 11 through 14 explaining how to use RPE as a means to practice mindfulness. In this episode, we share our continued explorations of how the concept of "working to a seven" can guide us throughout our lives.
