[Visualize] a negative outcome. We don’t want to plan for it, but we need to prepare for it so we know how to react. Can you keep it together and try again, or will you crumble under pressure?

  • Who is Ed Coan, and what does Stefi find most impressive about him? [18:05]
  • What are the differences in how the deadlift is approached, and how does someone cross the chasm into being able to defy gravity with weight that physics might suggest is impossible? [22:12]
  • If hard work beats talent when talent doesn’t work hard, how much do genetics factor into the success of an aspiring powerlifting juggernaut? What might someone with average physical attributes do to improve their deadlifting potential? [25:54]
  • What goes into a competition training split, and what a typical week of training looks like for Stefi. [35:13]
  • How do rehab and prehab figure into Stefi’s training? What is the question we should really be asking? [38:58]
  • What has Stefi done to recover from an injury that might differ from more common approaches, and what was the wake-up call that directed this course of action? [43:50]
  • You always need to consider the sources of your research because, as Dr. William Osler famously said, “Medicine is a science of uncertainty and an art of probability.” [50:54]
  • Because, as Stefi says, “pain isn’t a reliable sign of damage,” she lays out the problem with the question “What can we do to fix it?” and what we might ask instead. [54:07]
  • Taking the first steps in trying to pinpoint what might be causing back pain and what form its relief might take. [57:52]
  • My own experience with ketamine infusion and its effects on the pain from a long-term back injury, and Stefi’s thoughts on what may have transpired behind the scenes. [1:01:23]
  • How someone might develop greater resilience to prevent injuries from happening in the first place or at least diminish their likelihood, and why the concept of “bad” versus “good” form is relative. [1:04:44]
  • The benefits of adding certain exercises to our routine that extend our range of movement variability, and why Stefi believes it’s crucial to have a general physical preparedness (GPP) regimen if we’re training — especially in overspecialized sports like powerlifting and Olympic weightlifting, but really in any arena prone to repetitive motions, whether it’s playing tennis or sitting at a desk for hours every day. [1:12:02]
  • While she stresses that there’s no such thing as a magical exercise, Stefi shares her thoughts on The McGill Big Three — bird dog, dead bug, and side plank — and why they’re particularly efficacious in decreasing back pain. [1:15:50]

  • Books Stefi has gifted or recommended most. [1:29:21]

  • In the realm of physical therapy, what is it about Greg Lehman’s approach that stands out for Stefi? [1:37:40]
  • Winners never quit and quitters never win: false, in the life experience of Stefi Cohen. Bonus: what Stefi, in hindsight, wishes she hadn’t quit. [1:40:41]
  • As someone who completed her doctorate while training to break 25 world records and simultaneously creating a successful business, how does Stefi approach time management — and how did she wrangle the complication of scoring less than 75 on a test at a school that kicked people out for such infractions? [1:47:31]
  • Favorite failures that opened the door to unforeseen opportunities, and how pandemic and pain collaborated to nudge Stefi in the direction of a new sport. [1:57:04]
  • Six things you should do for any injury [2:03:38]:
  • Stop doing what hurts. [2:04:16]
  • Don’t underestimate isometric exercises. [2:04:33]
  • Increase aerobic activity. [2:04:48]

  1. I don’t do Twitter, and I wanted to recommend a book to you – especially after you mentioned enjoying Barry Lopez’s “Of Wolves and Men”. If you are looking for a stellar non-fiction book, I can’t recommend “Underland”, by Robert Macfarlane. It’s beautiful, haunting, and full of adventure. One of the best books of the past decade, in my humble opinion. If you appreciate good prose, a passionate author, and being immersed by fascinating details – you gotta check it out.

  2. RE: Stefi Cohen
    Hi Tim! I’m in trust that if you are meant to receive this it will happen 🙂 I will try to keep this brief but being someone who admires your intellect (A LOT) and I absolutely LOVE your podcast I wanted to reach out to you and let you know that there were many things Stefi mentioned that are simply false. One major thing being her statement “anyone can go and run” Being a biomechanics specialist running CORRECTLY is the most advanced thing one can do in their body. I get that she is a power lifter, but speaking from experience someone who comments on form, pain management and training techniques should have a solid gait cycle because that is how you measure “athletes.” Theres a method I really think you should check out / find FASCINATING. It is called FUNCTIONAL PATTERNS, which has been described as an “industry disruption” this company is literally changing the filed of movement when it comes to athletics, and getting all the gains with NO pain. Stefi mentioned a lot of injury and I would bet that in a decade, or as an elder woman she will be in a lot of joint discomfort. With functional patterns there have been evidence of bodies improving movement and strength with age. When it comes to results, pain management, postural improvement, gait health and overall well being these guys are changing the game.

    These dudes are literally fixing (I know I shouldn’t say that) parkinsons, and scoliosis.

    Check out [Moderator: IG link removed.] for amazing results
    the guy who created FP is Naudi Auguilar if you want to check him out as well. I think if you spoke to him your mind would be blown.

    Hope you are safe and healthy. With much love,

  3. I’ve read your books, and started listening your podcasts, and I noticed you mention Yerba Mate many times, and I actually guessing how do you drink it, because as Uruguayan as I am, we grow drinking Mate, but with hot water (around 80-90 Celsius), for what I know it’s as a infusion that Yerba mate release the most nutrients (I drink between 1 and 2 liters daily). Anyways, I’m loving the content you produce, keep it going!

  4. Hey Tim, great content but just wanted to highlight the newsletter emails that you send, are not very readable, eg subject line is too long. The font, size and bold is a bit less conducive for reading and strain to figure out useful stuff. But otherwise love the content.
