Embracing Strength Training



Speaking of biases.  For years when I passed by the weight-lifting gym on my way to a spin class or the pool I would glance over at the weight-lifters with a sense of superiority.  All these narcisstic guys in their muscle shirts and belts prancing around for hours staring at themselves in the wall-to-wall mirrors and occasionally straining to hoist some big weight.  I would congratulate myself on how I am meanwhile engaged in my much healthier sport of triathlon -- preparing for a great competitive endeavor with my triathlete community in the great outdoors.  

Being as scrawny and weak as I am though, perhaps I am just envious? And in any case my lack of strength seems to be my key limitation in triathlon. So this month I resolved to overcome my bias and embrace the sport of weightlifting  (at least for the off-season) especially given that: 



1. I increasingly hear that strength work is just as important (some argue MORE important!) than the triathlon type cardio/aerobic training for overall health (especially as you get older) 



 2. Like so many millions of people, I have been stressed over the thought that I am paying so darn much for my overpriced fitness club every month, and I am not adequately utilizing it



3. I crave quantifiable progress. With running and swimming it has been soooo hard to break out of my plateau - I long for the instant gratification of tangible improvement 





So my idea is to create more of a a sense of purpose around weight-training - instead of only half-heartedly going through the dreary motions of lifting -- I will try to lift a bit more every few weeks.  Like the Greek legend, Milo of Croton starting out with his newborn calf and lifting it everyday until he is lifting a full-grown bull.  Not that I am necessarily so concerned about being able to lift a bull.  Over 3-months of 3x per week progressive overload I just hope I can achieve some measurable improvement.  Perhaps it will benefit my running and triathlon performance.  Perhaps not.  Regardless, I embarked on my program a few weeks ago with a piece of notebook paper to jot my results and with great enthusiasm.   



And so far it is working!  For example with dips I add 1 more each session.  10 days ago I absolutely collapsed off the bars after 11, but then two days later I could do 12 before I collapsed.  Then 13.  Yesterday I did 16! 

It is so satisfying.  It seems the physiological benefit of progressive stress adaptation gets combined with the mental focus and confidence of doing just one more rep each session.  

It is like training for a half-marathon for me in earlier times before the plateau - every Sunday just add one more mile at like like 5:30 per mile. 






And I can admire myself in the wall-to-wall mirror

High intensity intervals vs Longer, slow, steady runs


After my last post I have been told that I am living in a high-intensity-interval “echo chamber.” In other words, I am like a climate change denier who only seeks out articles arguing that climate change is not occurring, and becomes caught in an "echo chamber" continuously being only fed yet more such articles by social media, search and his circle of friends, and where competing views are screened out.  I am only reading that high-intensity is beneficial, and long-slow marathon training is somehow “old-school” and “ineffectual” and more likely to lead to burnout and over-use injury (see my last post below).  Moreover, when I lead my weekly high-intensity hill repeats or run Wednesday intervals and ask this self-selected group of participants, they all heartily agree that sprinting up a hill at a crazed level of exertion is the ultimate healthy activity.  



Maybe there is a whole world of evidence that sticking to 100% longer, easier, aerobic runs is optimal?   Longer, steady-state runs seem to be what most of my marathon-focused teammates do almost exclusively, most all the time. Maybe they know something I don't?      


So in my effort to break out of my narrow, close-minded gated community, I find another computer, log-in with a different name and seek articles on the merit of longer, steady exercise.  My search delivers an odd assortment of viewpoints --



My quick reaction - 

1. Wow - there are people that do ONLY high intensity training?
Apparently there is this whole world of sedentary Americans whose only exercise is Crossfit and intense treadmill workouts.  My heart cries out - I feel such sympathy for them.  

2. For runners just 10-20% high intensity seems more appropriate 

3. My triathlete teammates scoff at this idea of long, aerobic base training as "just so 1970s" favoring "reverse periodization"

4. Importance of seasonality - Yeah, yeah, yeah,  see  my "off season" post among others below

5. Reading all these long paeans to the spiritual joy of really really long runs is even more boring than really really long runs

6. Ultimately my effort to be open-minded is an abysmal failure.  Alas, the most compelling data point I stumbled across was this article which largely supports my prevailing view (bias).  The US Military(!) -- that same institution that produced the original 1960s era data on the health benefits of long running — has decided to increase the intensity of their troop’s training and reduce the volume of running based on extensive evidence of over-use injuries and troop performance.
