Every week on the podcast, Greg Nuckols and Eric Trexler answer listeners’ questions and ask industry experts about anything and everything related to training, nutrition, science, and life in general.
Here, we’ve compiled all of the miscellaneous (education, research, business, and cooking) questions answered on the podcast so you can quickly jump around and find the content you’re most interested in.
You should also subscribe on Apple Podcasts, Google Podcasts, Stitcher, or wherever you get your podcasts to make sure you’re getting new episodes and answers to your questions every week.
All questions
- Education and Building a Business
- I am a newly certified personal trainer, and I am planning to submit applications for personal trainer positions at commercial facilities in a couple weeks. How does a new trainer know when they are “ready” to take on clients?
- I’m a first year psychology student. We recently had a class on how to read research articles, and many course materials laid out processes that would take about 5-6 hours for every single paper. What is your process for reading research? Does this change when you’re trying to get acquainted with a whole new body of literature versus evaluating a single paper on a familiar topic?
- Discussion about creating fitness content (with Jeff Nippard)
- Interview with Jeff Nippard: On genetic limits, FFMI, training, and nutrition
- Do either of you have any recommendations on how to seek out a quality academic reference, without being a complete jerk about it? How can someone with aspirations of becoming a researcher get their start in the research world?
- I was wondering if you guys could provide any advice for students looking to improve their writing skills for science-based fitness articles. Related to that, what would be a useful approach for getting published on well-known websites?
- In a recent podcast you suggested buying an exercise physiology textbook. Is an old edition of a textbook worth reading, or would there be too much outdated information?
- What are some of the best reading materials you’d recommend for a trainer that is just starting out?
- What are some of the biggest tips you would give someone who wants to get into an exercise science program at a university and excel academically?
- What would happen if Terry Tao started studying exercise science? What kind of progress would the field make?
- A few scientific fields have recently identified issues with replication, reproducibility, and transparency in research. How prevalent are these issues in exercise science?
- How did you (Greg) build a following in the fitness industry?
- What advice do Greg and Eric have for students pursuing a degree in exercise science?
- What are some big things that you’ve changed your mind about over the years?
- What what were the early days of evidence-based fitness like?

- Is the Dunning-Kruger effect based on legit evidence?
- What are the most common errors that you see people make when interpreting statistics?

- Effect size discussion
- How much evidence and research would it take for you to implement new findings into your own practice? One study with a large effect size, or multiple replicated studies?
- How do you reconcile value for research, with the likelihood that there’s some degree of really bad research out there, and that many people can’t tell the difference between good and bad research?
- What is the state of research in exercise science and sports nutrition?
- Training studies are often quite short, and in relatively untrained people. Do the results from these short-term studies translate to long-term differences over a training career?
