Going deeper
“The single most important thing you can do, having finished this brief, is to make a decision about what you will do this week.”
This brief is a starting point, not the last word. Members who want to go deeper will find the resources below useful. The list is deliberately not comprehensive the exercise and longevity space is full of noise, and the point of this section is to flag the sources we consider genuinely worth your time. Different members will find different resources useful at different points. We have tried to give enough information for members to choose well rather than reading all of them.
The list is organised into books, podcasts, and newsletters. Each comes with a brief note on what makes it worth reading.
Books
Outlive: The Science and Art of Longevity Peter Attia, 2023
The single most important book for anyone serious about exercise and longevity. Attia is a physician whose practice focuses on extending healthspan, and the chapters on exercise in Outlive particularly those dealing with VO2 max, Zone 2, strength, and what he calls the centenarian decathlon are the foundational text for the framework used in this brief. Attia can be dogmatic, and his approach is more interventionist than Forever Well's in some areas, but the exercise sections are clear, rigorous, and practical. Start here if you read one book.
Forever Strong: A New, Science-Based Strategy for Aging Well Gabrielle Lyon, 2023
Lyon is a physician who trained under the protein researcher Donald Layman, and her book is the best lay-reader articulation of the muscle-centric view of ageing: that skeletal muscle is the most important organ for healthspan, that protein intake and resistance training are the two levers that build and protect it, and that the standard nutritional and fitness advice for older adults systematically underrates both. Reads naturally as the strength-training and protein complement to Attia's broader longevity framework. Particularly useful for members who are convinced they need to train but have not understood why strength specifically matters so much.
Built to Move Kelly Starrett and Juliet Starrett, 2023
A practical book on mobility and movement quality written by two of the most influential physical therapists in the English-speaking world. Organised around ten simple assessments getting up off the floor, standing on one leg, touching your toes each with accompanying mobility practice. Less about longevity science and more about the everyday movement capacity that the science translates into. Particularly useful for members at the Build on it and Optimise tiers who want a structured way to keep mobility and movement quality improving rather than quietly declining.
Younger Next Year Chris Crowley and Henry Lodge, 2004
An older book, written for men but with a companion volume for women, and deliberately pitched as motivational rather than technical. The core argument that the biological changes typically attributed to ageing are in fact the biological changes of sedentary ageing, and that serious exercise into old age reverses most of them is now well supported by the research that followed. Less rigorous than Outlive but more immediately actionable for readers who need to be convinced before they start. Worth reading alongside Attia, not instead of.
Spark: The Revolutionary New Science of Exercise and the Brain John Ratey, 2008
The single best treatment of the exercise-and-cognition relationship for the general reader. Ratey is a Harvard psychiatrist who noticed that his patients who exercised did markedly better than those who did not, and Spark is his attempt to explain why. The book covers the effects of exercise on depression, anxiety, attention, learning and age-related cognitive decline, with enough neurobiology to be interesting and enough clinical grounding to be practical. Dated in places some of the specific mechanisms have been refined since 2008 but the central argument has aged well.
Fast After 50 Joe Friel, 2015
Specifically written for endurance athletes over 50 who want to understand how to train effectively as they age. Friel is a coach with decades of experience working with masters athletes, and the book addresses the real questions members in this demographic face: how much recovery do I need, how does my VO2 max decline, how should I periodise, how do I stay injury-free. More technical than the others in this list, and aimed at members who are already training seriously. Particularly relevant for Optimise-tier members in their 50s and 60s.
Podcasts
The Drive Peter Attia
Attia's podcast is the single most rigorous long-form conversation about exercise and longevity in audio format. The exercise episodes in particular especially those with Andy Galpin, Iñigo San Millán, Mike Israetel and Stuart Phillips cover the evidence in depth with working scientists and coaches. Individual episodes run two to four hours, which some members find heavy going; others find nothing else matches the depth. Particularly worth searching the archive for specific topics (Zone 2, VO2 max, protein, sarcopenia) rather than trying to listen through chronologically.
Huberman Lab Andrew Huberman
Stanford neuroscientist Andrew Huberman covers a wide range of topics, and his exercise-focused series particularly the Foundational Fitness Protocol episodes and the conversations with Andy Galpin are among the clearest and most accessible explainers available. More neuroscience-inflected than The Drive, which is a strength when covering topics like the cognitive effects of exercise, and a mild weakness when he strays from neuroscience into areas where other specialists would be more authoritative. Start with the Galpin series.
Found My Fitness Rhonda Patrick
Patrick is a biochemist who covers exercise, nutrition and ageing in considerable depth. Her episodes on VO2 max, heat exposure, strength training and the cognitive effects of exercise are all worth your time. Particularly strong on the connections between exercise and specific longevity interventions exercise combined with sauna, exercise and time-restricted eating, exercise and specific supplements. Less practitioner-focused than The Drive, more biochemist-focused. Complementary rather than a substitute.
Barbell Medicine Podcast Jordan Feigenbaum and Austin Baraki
If you develop an interest in the strength training area specifically, this is where to go for the deepest practitioner-focused treatment. Feigenbaum and Baraki are both physicians and competitive lifters, and their content on programming, progression, injury management and the evidence behind strength training is unmatched in the English-speaking podcast world. More technical than members at Tier 1 will need; essential for members at Tier 3 who are taking strength training seriously.
Newsletters and writing
Peter Attia's weekly email
If you want one weekly email on longevity science, this is the one. Attia's team writes rigorous short summaries of new research, practitioner-focused deep dives, and clinical commentary. Paid subscription, fair pricing for what you get, and particularly strong on exercise topics.
Examine.com
Not strictly a newsletter but the best single evidence-review resource for supplements and interventions used alongside exercise. Their pages on creatine, vitamin D, protein, omega-3 and beta-alanine are the reference standard for getting the evidence straight on how each interacts with training. Particularly useful when you read a claim about a supplement or intervention and want to know what the actual research says rather than what a YouTube video says it says. Paid subscription for full access.
Chris Beardsley Strength training research summaries
Beardsley is a strength-training researcher and writer who publishes clear, evidence-based summaries of the academic literature on resistance training covering specific topics like fatigue, time under tension, training to failure, hypertrophy mechanisms, and programming variables. More technical than members at Tier 1 will need; very useful for members at Tier 2 and 3 who want to understand the science behind their strength training rather than relying on heuristics. Available through his Patreon and Medium publications.
Apps
Sworkit
A genuinely useful tool for the how long, not whether principle from sections 4 and 6. You tell it how much time you have (5, 10, 20, 45 minutes), the area you want to work (upper body, lower body, full body, cardio, stretching), and your level and it gives you a guided routine to follow. Particularly good for the day when you have ten minutes free and would otherwise do nothing because you couldn't decide what. Removes the friction of needing to plan a session for yourself. Free tier covers most use cases; paid tier adds more variety. The only app on this list we recommend without much qualification.
Strava
Strava records your runs, walks, cycles, swims and other activities, and lets you track progress against yourself, friends, and the wider community. The personal-history function is the genuinely useful part looking back over a year and seeing the gradual improvement in your Zone 2 pace at the same heart rate is one of the more satisfying confirmations that the training is working. The community and competitive elements (segments, leaderboards, kudos) work well for some members and feel pressuring for others; the app is fully usable with all of that switched off. Free tier covers most use cases; paid tier adds detailed performance analytics.
Forever Well's own content
[FOREVER WELL PLACEHOLDER]
Forever Well newsletter, podcast, blog, or digital platform content specific to Exercise should be referenced here. Covers planned content streams once they launch Andrew Hull's podcast, written pieces from the Forever Well team, platform-native exercise content, recorded sessions from the Blue Zone retreats. To be filled in once the content strategy is confirmed.
A last word
The research on exercise and longevity is one of the clearest and most consistent areas in the whole health literature. The gap between what we know and what most adults do is vast, and the individual members who act on the knowledge age very differently from those who do not. None of the resources above will do the training for you. What they will do is give you a clearer sense of why the training matters, and for members who need it the motivation to start and the confidence to keep going.
The single most important thing you can do, having finished this brief, is to make a decision about what you will do this week. Not what you should do, or what you mean to do, or what you will do once things calm down. What you will do this week. A thirty-minute walk on Tuesday evening, or a strength session on Saturday morning, or a conversation with a trainer at the local gym. Something concrete, something small enough to succeed at, something that begins the pattern that the rest of this brief describes. The biology will take care of itself. The hard part is the decision.
