Which Stats to Track (and Which to Ignore)

 https://www.outsideonline.com/2197776/which-stats-track-and-which-ignore

Stats to Track:

  1. Heart Rate Variability (HRV): The more relaxed, free from fatigue, and trainable you are, the greater the variability between heartbeats. Low HRV signals that your body is under too much stress and not ready for intense workouts.
  2. Workout Volume and Intensity: monitoring daily and weekly workout volume (exercise frequency and duration) and intensity can help ensure that you are pushing when you need to and tapering when the time comes.
  3. Rate of Perceived Exertion (RPE): Rank your RPE according to the Borg scale, which runs from 6-20. (Fun fact, WHOOP Strain is based on the Borg scale, where RPE maps on a nonlinear function from 0-21). Use the scale to guide training efforts–harder tempo runs should rank much higher on the scale while longer recovery runs should ran lower, giving your body time to recover.

Stats to Skip:

  1. Calorie Equation: The macro- and micronutrients you’re getting as you push your body in training efforts is far more important than calorie count. User your energy level as a barometer for whether you’re fueling properly.
  2. Training Heart Rate (Sometimes): Heart rate zones are typically calculated using age-predicted max heart rate equations, where global comparisons may not be appropriate for your fitness level and training habits. Heart rate zones and lactate thresholds can be effective training tools when specifically geared to your body.
  3. Racing Weight: trying to lose weight while training is detrimental, as you can’t hit Pos when in caloric deficit.

Your Brain Can Only Take So Much Focus

https://hbr.org/2017/05/your-brain-can-only-take-so-much-focus

How to activate the DMN during the day:

  1. Positive constructive daydreaming: choose a low-key activity such as knitting, gardening, or casual reading and then wander into the recesses of your mind.
  2. Taking a nap: after a ten minute nap, studies have shown that you become clearer and more alert. If it’s a creative task in front of you, you will need a full 90 minute nap to completely refresh the brain.
  3. Pretending to be someone else: When you’re in a creative deadlock, try embodying a different identity. It will likely get you out of your head and allow you to think from a different perspective.
