12 Inescapable Truths About Endurance Training

Physiologist Stephen Seiler is U.S.-born but has been living and working in Norway for a long time. He’s generally credited as the father of the 80/20 training program. Below he “distills” what he has learned from 30 years of engaging in, studying, and teaching endurance physiology. It’s as good a list of training truths as you’ll find.

Among them, a couple of my favorites:

“Training is an optimization challenge, not a maximization challenge.”

And:

“Great coaches and athletes are not afraid of ‘intelligent failures.’ ”

Also:

“Physiology is COMPLEX, but training prescriptions should NOT be.”

Finally, don’t miss number 12. It tells you how to put the training pieces together. Which is of course the crux of the entire process.

And 8 Fitness Myths You Should Totally Ignore

While Stephen Seiler makes excellent points about training, the New York Times wants you to ignore eight fitness myths that could sidetrack your efforts. Several of these are mainstay subjects at RLRH, especially the myth that “Running destroys your knees.” Thank you, NYT, for setting the record straight to your massive audience.

Also, you shouldn’t believe that just because you’re a runner, you don’t need to strengthen your legs. Sure, your legs are already road-proven. But leg-strengthening work “can improve bone density and lower your risk of injury — and make you a stronger ​runner​ or ​cyclist​, too.”

You probably know that stretching has not been shown to reduce injuries or improve performance, but you might not realize that ​recent research​ indicates “lifting relatively light weights for, say, 30 repetitions is just as effective at building muscle and strength as lifting weights that feel heavier for five to 12 reps.” In fact, it might be better at building muscular endurance.

My favorite myth: “Modifications are for beginners.” I’ve learned that I need to modify almost every exercise I see in pictures or videos for my own strength level (or lack thereof), and for my own tightness. I thought I was cheating by doing this. Now I’m happy to learn I’m a smart modifier. You should learn to be accepting of your own training modifications.

Here’s A “Snack” You Should Have Several Times A Day

The American College of Sports Medicine publishes a regular “Health & Fitness Journal” that doesn’t introduce new studies but rather tips, advice, and health-fitness wisdom from sports medicine professionals. The January issue includes “24 Fit Tips For 2024” and “10 New Things To Try In 2024.”

The below links don’t give you access to the full text of these articles, but do allow you to peruse significant portions. Here are two ideas that I particularly liked.

From Fit Tips: “Schedule, schedule, schedule: anchor at least three times per week that are non negotiable events for your exercise routine.” If you don’t put workouts on your calendar, it’s far too easy to watch them evaporate and disappear as life intervenes with its myriad demands.

From New Things: “I resolve to take more snacks.” This is not nutrition advice. Rather it refers to “exercise snacks,” a new term that refers to short [several minutes] cardio and strength routines that you do regularly throughout the day. You can also call it VILPA for “vigorous intermittent lifestyle physical activity.”

The key idea: You want to break up those long periods of sitting at your desk or on the sofa. Even if you do a 60-minute workout at some point, you should avoid long sitting the rest of the day. A 2023 study showed that increasing your VILPA sessions to 3 to 4 minutes (rather than just 1-2 minutes) “was associated with a decreased cancer incidence in a dose-response manner.” That is, the longer the VILPA, the greater the cancer reduction.
