Thanks for the nice words and also thanks to Peter for chiming in too. You are both right about ME. There are more forms of ME than you can shake a stick at. And most of them work across a wide range of event goals. That’s what has made gym circuits and HIIT protocol ME like Cross Fit and the Gym Jones and other copy cat models so popular. They’re effective at improving local muscular endurance (work capacity) in some of the major locomotive prime mover muscle groups. We really should be calling what we do ‘L’ME but I chose ME many years ago because people got confused wen I added the “Local” in front. Anyway…..So, even though you are not going to be Burpeeing your way up Liberty Ridge the transfer of the training effect to climbing steeply uphill from doing burpees till you puke is significant and you will feel it.
As we mentioned in our book ME training has been a mainstay of conventional endurance sport training methodology for nearly a hundred years. Yuri Verkhoshansky wrote extensively about employing it for track runners back in the 1980s. When I was young swimmer in the late 60s and 70s my coaches employed it. What is different in these current fitness fad models is that they build the entire program on ME. They see its effectiveness and draw the natural (although wrong) conclusion: This shit works so well lets just use it 24/7! After all why bother with that low intensity aerobic base stuff when you can’t really tell that it does much or even anything, whereas they see immediate and powerful gains from employing LME. All the traditional sports have tried this myopic approach many times over the decades and each time rejected it and come back to a more periodized and limited use of LME. Why? because it provides the best results long term.
Sorry for the digression but I hope you can appreciate the history lesson. As with any history: If you do not heed its lessons you are doomed to repeat the mistakes of the past.
While Peter is right that sport specific LME is going to give good results for you, the semi-specific movements of Lunges, box steps, split jump squats, even burpees (confusedly these fad LME programs use burpees because they want a “cardio” effect – don’t ask or I’ll go on another tangent). John, you can effectively mix in some circuit style, gym based LME workouts without upsetting, and in all likelihood helping your progression. Especially if you have limited access to the kind of terrain needed for the TftNA weighted carry ME workouts. We use gym LME circuits for lots of our coaching clients who are stuck with gyms rather than mountains.
Use the same guidelines with the circuits as with the outdoor ME. Don’t over do them and keep the aerobic Z1-2 volume high during the ME phase.
I hope this helps
