Insights From An Expert: Mindset And Individualized Training For Endurance

Insights From An Expert: Mindset And Individualized Training For Endurance

Tim “Lucho” Waggoner, formerly Luchinske, resides in the mountains of Colorado just outside Boulder and is a highly sought-after endurance coach. On Endurance Planet he’s the vastly popular expert and co-host on “Ask the Coaches” (ATC) show. His experience in sport as both a professional triathlete and elite ultrarunner brings an incredible wealth of knowledge to the show.  Lucho started running at the age of 10 and went on to multiple Kansas state track and field championships and was a two time All-American in college. He decided to drop out after two years and travel eventually settling in the U.S. Virgin Islands where he lived for four years. 

Tired of the party lifestyle, he quit smoking and entered his first triathlon and placed third. Fast forward, and four years later he placed 16th overall at the Ironman World Championships in Kona, Hawaii, and was the top amateur.  After 15 Ironmans and beginning a family, Lucho switched to running. He ran 2:41 in his first marathon and then 2:30 in his second. Eventually, Lucho and his wife moved up to 8,200ft altitude in the mountains, and this led him to try ultrarunning. In his first race, a 50-mile trail race, he won and broke the course record. 

He then went on to place 6th at the Leadville 100—his 4th ever ultra. To top it off, Lucho was the overall winner of the Leadman series in 2012, which includes all of the Leadville races. He now spends most his time raising his two sons, coaching athletes, and training for master’s track & field racing.  He also (sometimes) has a badass beard and occasionally blogs words of wisdom at

How To Get The Results You Want By Using Effective Change Strategies

How To Get The Results You Want By Using Effective Change Strategies

L. Michael Hall Ph.D is a prolific author in the psychology and self development field, having written 66 books, 40 serial books, and over 100 published articles.

He completed his doctorate in Cognitive-Behavioral psychology from Union Institute University in Cincinnati Ohio, with his dissertation completed on the languaging of four psychotherapies, including NLP, RET, Reality Therapy, and Logotherapy using the formations of General Semantics.

Dr. Hall has conducted private therapy in practice for 20 years, and also ran an NLP training center for 10 years.

He has co-founded Neuro-Semantics, Meta-Coaching, and the NLP Leadership Summit, and also collaborated with Richard Bandler, the co-founder of NLP, having written several books for him.

Dr. Hall is clearly a distinguished expert in his field and I credit him with much of my own personal development over near 20 years through his writings and to say I’m happy to finally be speaking with him on my very own podcast is an extreme understatement.

Episode Highlights:

1. What is Neuro-Linguistic Programming?

2. What got you interested in NLP and Hypnosis as a Cognitive Behavioral Therapist?

3. How did it change your way of thinking?

4. You've developed your own model NeuroSemantics.  What is different about NS vs NLP?

5. One of the most significant things I've learned from your work is the Meta-States model. Can you share with us what this is? What can this model help us with?

6. We can know things logically, but still not do them.  This is largely the challenge that health professionals face with patients and clients, from losing weight, getting to bed on time, to avoiding drugs and alcohol, and doing more exercise. What is happening here? It appears we've long known that just understanding things doesn't change things, but we don't do anything about it.

7. One of the patterns you've mentioned in your books is the Mind to Muscle pattern.  Can you talk a bit more about what this is and why it's important?

1.  Can you give us a little history around your work in nutrition and how it led to your current approach to nutrition?

2.  We hear the word "inflammation" a lot when it comes to the body.  Can you tell us what that specifically means when it comes to mind for you in your work?

3.  Inflammation is tied into pain.  What is your experience in helping people with pain reduce inflammation and the results you have seen?

4.  Is being "overweight" a problem for having inflammation?

5.  Are there any specific tests you can run to determine how much inflammation you have?

6.  Most people deal with inflammation by taking things like anti-inflammatories, but I think we generally know taking a lot of this stuff isn't good, but what particularly happens when we keep dosing ourselves with things like ibuprofen to reduce inflammation?

6.  Inflammation in the gut is a hot topic right now, and in particular something called SIBO.  Can you give us a rundown on what SIBO is, and what are the common symptoms associated with it?

7.  So what do you do to reduce inflammation in the body?  What are your general recommendations?

8.  What's most exciting in your field of work right now?  What's new and awesome and on the horizon?
