    How to Perform When Fear Is Real: Resilience, Stress Exposure, and Leadership with Ash Alexander-Cooper OBE

    Fear is easy to talk about in theory. It is harder when the stakes are high, and you still have to think clearly, lead others, and perform. In this episode of Optimising Human Performance (OpHP), Martin I Jones speaks with Ash Alexander-Cooper OBE about building resilience, courage in the face of fear, and empowering leadership in high-stakes environments. You will learn how to stay functional under pressure, why fitness reduces cognitive load, how leaders build trust fast in complex environments, and a simple STOP reset technique to interrupt stress spirals. Ash shares personal stories that begin with childhood instability and the search for belonging through high-performance music and sport, before an “accidental” decision led to a 20+year military career. Ash explains that resilience is not a personality trait but a capability built through realistic training, repeated exposure, and physical readiness, thereby freeing the mind to think clearly under pressure. Guest, Cast, & Crew Ash Alexander-Cooper OBE is a former soldier, athlete, artist, and award-winning international musician. During a three-decade career, Ash served as a helicopter pilot, an airborne jungle-warfare and counter-terrorism specialist, and spent seven years deployed in some of the world's most challenging environments. Wounded multiple times, Ash proudly supports several veteran charities as a vocal mental health campaigner and advocate. Since retiring from the military, he's focused on leadership and resilience, and he's now a sought-after international keynote speaker and strategic advisor supporting those seeking to overcome adversity, adapt, and win in today's increasingly complex world. Hosted by Martin I. Jones https://www.ophp.co.uk  Produced & edited by Bess Manley Key takeaways Why resilience is often forged through hardship, not discovered through motivationHow realistic training and stress exposure build functional calm under pressureWhy physical fitness can reduce cognitive load and improve decision-makingA leadership model for complexity: trust, purpose, shared consciousness, empowered executionHow authentic leaders share context, invite challenge, and empower teams rather than control themA practical reset tool: the STOP technique to interrupt stress spirals Resources Ash’s website: https://www.ashalexcooper.com/  Ash’s book: https://www.waterstones.com/book/mindful-soldier/ash-alexander-cooper/9781529450644 Follow Ash on X https://twitter.com/ashalexcooper Follow Ash on Instagram https://www.instagram.com/ashalexcooper/ Follow Ash on Facebook https://www.facebook.com/ashalexcooper/  Chapters 00:00 Welcome and guest introduction 00:26 Resilience and courage teaser 01:43 Meet Ash Alexander-Cooper 02:01 From music to military 03:04 Why he wrote the book 04:27 Childhood instability and its impact 06:08 Refuge in teams and performance 08:50 An accidental start to a military career 11:36 Why he stayed in 13:36 First ambush, injury, and trauma 16:02 How training builds resilience 19:09 Stress exposure without combat 19:45 Physical fitness frees the mind 21:56 Human performance and adaptation 24:12 Brain sabotage in racing 25:50 Accidental marathon fueling 26:43 Leadership basics that matter 27:14 Team of Teams framework 31:41 Building trust fast 34:15 Complexity and sharing context 36:54 Psychological safety in action 38:35 Resilience toolkit from the book 40:15 STOP breath reset technique 43:47 Where to find the book 45:47 Courage through fear zone 47:07 Final thanks and call to action If this episode helped you, follow Optimising Human Performance, share it with someone leading under pressure, and leave a quick review.

  4. Perspective, Pressure, and Performing Through Adversity with Dr Andrew Wood

    18 MARS

    Perspective, Pressure, and Performing Through Adversity with Dr Andrew Wood

    What if the biggest obstacle to performing under pressure isn't the situation itself, but the way we think about it? In this episode, Martin talks to fellow psychologist and world-leading expert on pressure and adversity, Dr. Andrew Wood, about the strategies and philosophies that can help you take control of the irrational beliefs that often hold us back. We discuss rational emotive behaviour therapy (REBT) and how irrational core beliefs fuel pressure, anxiety, and maladaptive behaviour. Andrew explains REBT’s focus on flexible, rational beliefs, distinguishing helpful vs unhelpful responses rather than positive vs negative thinking, and introduces concepts like awfulizing & low frustration tolerance. He describes tools such as the “badness scale,” 10-10-10 perspective taking, humour, and testing beliefs through controlled exposure to feared situations. Andrew also discusses leadership climates that normalise all-or-nothing thinking, and shares his own long COVID experience, bedbound for a year, identity loss, and using rationality, values and symptom-tracking to cope, ending with reflections on reconciling fear of death to reduce everyday fears. Guest, Cast & Crew Dr. Andrew Wood is a Performance Psychologist, keynote speaker, and published researcher specialising in rational thinking under pressure. Drawing on over a decade working with elite athletes, emergency services, corporate leaders, and his own lived experience navigating life-changing disability, Andrew's work sits at the intersection of science, story, and practicality. He doesn't just teach people how to think more clearly and perform at their best when faced with setbacks, he's also had to do it himself, when it mattered the most.

  5. Embracing the Unknown with Solo Ocean Rower with Annasley Park

    Embracing the Unknown with Solo Ocean Rower with Annasley Park

    Former GB cyclist-turned-adventurer and solo ocean rower Annasley Park has built her life on the value of fortitude. In this episode of the Optimising Human Performance Podcast, she shares her journey, including her experiences with injury and burnout. She introduces the ‘fortitude mindset’, built on feral intelligence, visualisation, and emotion, and shares practical routines that anchored her through fear, fatigue and uncertainty. Guest, Cast & Crew Annasley Parks speaks from lived experience about leadership under pressure, performing in uncertainty, managing fear, and sustaining high performance without burnout. At just twenty-nine years of age, she is the ninth solo, unsupported and independent woman in history to row three thousand miles across the Atlantic Ocean. A former professional cyclist, white-water raft instructor, Alpine chalet manager and superyacht deckhand. Annasley has spent over a decade working in demanding and unpredictable environments where resilience, adaptability, decision-making under pressure and self-leadership were essential skills. Growing up on the military estates of Herefordshire, Annasley found her freedom in the mountains through sports, ultimately building a professional cycling career with the Great Britain Cycling Team, competing on the road and track, and signing for a UCI World Tour-level road team. However, injuries cut this chapter short, teaching her early lessons in rebuilding and resilience when identity and purpose is lost. She went on to explore unconventional career paths that took her from source to sea. From Alpine chalet management to white-water rafting on the American rivers, and four years serving as a deckhand on superyachts, travelling all over the world with high-profile clients. Annasley gained unique insights into navigating diverse environments and thriving outside the conventional structures. Despite her physical, mental and emotional fortitude, Annasley experienced severe burnout in 2023. That period led her to question what truly sustains people when pressure rises, plans fail, fear sets in, and motivation runs out. Her Ocean Survivoar Challenge became the ultimate test of all the knowledge, skills, resources and networks she had developed. In less than a year, she brought the project to the starting line, assembling a world-class team of experts in ocean rowing, communications, medical and equipment support, and more, ensuring the expedition's success. Her Atlantic row was more than a test of endurance. It was a journey into the critical 20% zone. An unpredictable space she calls the messy middle, a threshold of transition where you are no longer who you once were, but not yet who you are becoming. This is a space where human capacity outlasts the plan. The lessons she learned in that zone form the foundation of The Fortitude System, built on the disciplines of solitude, magnitude and attitude of any given challenge or faced adversity, helping audiences convert chaos into clarity, overwhelm into sustainable performance and fear into action.

    The Future of Female Soldiers: Training, Nutrition, and Menstrual Health in Military Optimisation

    In this episode, Dr Julie Greeves, principal physiologist for the British Army and expert in applied human physiology, shares groundbreaking research on female soldier health, injury prevention, and performance optimisation. Dr. Greeves unpacks the Women in Ground Close Combat research program, and explains what it tells us about physical performance, load carriage and reproductive health. Listeners from defence, sports, or health sciences will benefit from these insights, which can help tailor training and policies for women in demanding environments. We discuss the implementation of physical employment standards, the importance of nutrition, menstrual health and sleep for female soldiers, and the steps required to help women thrive in strenuous roles within the military. Key Takeaways: Development and implementation of gender-specific physical employment standards and their impact on female recruitment.Physiological differences between men and women: skeletal structure, muscle mass, cardiovascular capacity, and susceptibility to injury.Injury risk factors: higher stress fractures and bone injuries in women, especially during initial training phases.Benefits of female physiology: metabolic advantages, increased fat oxidation during prolonged submaximal exercise, and potential to reduce injury risk with appropriate systems.The myth of training around the menstrual cycle and its practical, science-backed inaccuracy.Hormonal fluctuations, menstrual health, contraceptive use, and their impacts on performance and injury risk.The importance of micronutrients like iron and calcium for women in military settings.The role of sleep, stress, and the gut-brain axis in psychological health and performance, with sex differences in cortisol responses.Practical advice for individuals preparing for arduous training: targeted load carriage, resistance, nutrition, and tracking menstrual health. Guest: Julie is the Head of Army Health and Performance Research in the British Army. After obtaining her doctorate in female physiology, Julie has spent over 25 years pioneering original research on musculoskeletal health and human performance in the military. Julie's research has widely informed Army and Defence policies, and she was decorated with an OBE in 2017 for her scientific contribution to the opening of Ground Close Combat roles to women. Julie holds honorary Chair appointments at the School of Medicine UEA and UCL and has published over 140 original papers in peer-reviewed journals.

    Are You Born to Run on Less Sleep? A Neuroscientist's Guide to Genes, Fatigue, and Practical Strategies for High-Stress Environments: With Dr Allison Brager

    In this episode, Martin & JP talk to Dr Allison Brager, an active-duty Army officer and neuroscientist specialising in sleep and fatigue research. Dr. Brager shares her pioneering research on how both acute and chronic sleep deprivation affect physiological, cognitive, and emotional performance, especially in high-stakes environments. She breaks down the genetic factors that make some individuals resilient to sleep loss, debunks common myths about "training" yourself to need less sleep, and reveals the critical role of sleep in energy (ATP) production outside of the brain. Plus, learn about the military's evidence-based strategies for managing inevitable fatigue, including the best way to use strategic caffeine dosing. Key Takeaways: Acute (Forced Wakefulness): After 18 to 24 hours, an individual struggles to recover performance without a sleep opportunity.Chronic (5 hours/night): Three days of chronic restriction lead to a decline in physiological, cognitive, and emotional state approaching clinically significant levels (e.g., a 50% drop in testosterone).Genetic Resiliency: A naturally occurring mutation in the adenosine receptors can make individuals more resilient to sleep deprivation, slowing the rate of decline in performance under forced wakefulness.The Sleep-First Principle: Sleep is the biological foundation for readiness. It is necessary to replenish glycogen and fat reserves (ATP/energy homeostasis) to support high-intensity training and performance the following day.Nap Strategy: A simple 20-minute nap or "chill time" can significantly increase productivity, morale, and unit welfare in operational settings.Strategic Caffeine Dosing: Do not wait until you feel tired to take caffeine; it's already too late.SLANT Acronym: Optimise a suboptimal sleep environment by controlling Surface, Light (use red light, eye masks), Air quality, Noise (use earplugs), and Temperature.Busting the Morning Caffeine Myth: Dr. Brager states that for an individual with an entrained circadian rhythm, morning caffeine has a minimal effect on the body's ability to use light as a time cue. Light is the most potent time cue, and the idea that you must wait hours after waking up to consume coffee is generally considered "nonsense." Guest, Cast & Crew Dr Allison Brager is a highly respected neurobiologist and active-duty US Army officer with expertise in neuroscience, sleep, and circadian rhythms. Her work examines substrates and mechanisms of resiliency to extreme environmental stress in Special Forces and other elite populations during intense maritime, aviation, and land-based training and operations in Antarctica, the Central American rainforest, and other austere environments. Her popular science book, titled Meathead: Unravelling the Athletic Brain, links exercise physiology and neuroscience to her experiences as an elite athlete.

À propos

Optimising Human Performance is the podcast for people who can’t afford to fail. If you work in the military, defence and security, emergency services, first response, elite sport, or any other high‑pressure environment, this show gives you practical, evidence‑based tools to perform at your best when it matters most. Hosted by Dr Martin I. Jones and Jonpaul Nevin, the podcast brings together world‑leading experts, cutting‑edge science, and hard‑won field experience. Martin is a sport psychologist with over 20 years of research and applied experience. He holds advanced degrees from Loughborough University and the University of Oxford, has authored more than 50 peer‑reviewed publications, and previously served as Principal Advisor for Human Performance and Human Augmentation at the UK’s Defence Science and Technology Laboratory (Dstl). He has also represented the UK on NATO’s Human Factors and Medicine panel.Jonpaul is a former British Army soldier with 15 years of service in the Royal Engineers and the Royal Army Physical Training Corps and is an associate professor at Buckinghamshire New University.Together, Martin and Jonpaul explore how to optimise physical, psychological, and cognitive performance in contexts where the stakes are high, the margins are thin, and the cost of failure can be severe. In each episode, you’ll hear from guests such as leading scientists, military and emergency services professionals, elite coaches, clinicians, and operators who have performed in extremis. Conversations blend rigorous research with real‑world application, making complex science accessible and directly applicable. Topics include: Sleep, circadian rhythms, and fatigue management for shift workers and night operationsMental toughness, resilience, and emotional control under pressureDecision‑making in high‑stress, uncertain, and time‑critical situationsRecovery from brain injury, trauma, and long‑term exposure to stressTraining, preparation, and debriefing practices used by elite military units and sports teamsSustaining performance and wellbeing across long careers in high‑risk, high‑responsibility rolesAcross the series, you’ll learn: How to design sleep and recovery routines that work in the real worldHow to recognise and manage the cognitive and emotional effects of stress, fear, and fatigueHow to build habits and systems that protect performanceHow to translate laboratory findings and academic research into simple, repeatable practices you can use on duty, on operations, or in competitionHow to communicate, lead, and support others when they are operating at – or beyond – their limitsThe focus is always on what you can actually do: checklists, frameworks, mental models, and small, practical changes that make a meaningful difference in demanding environments. Episodes are designed so that you can take at least one actionable idea back to your unit, team, watch, squad, clinic, or organisation. Whether you are a commander, paramedic, firefighter, police officer, intelligence analyst, surgeon, coach, or performance specialist, Optimising Human Performance will help you: Understand the science behind human performance in high‑stakes situationsApply that science to your own contextImprove your ability to think clearly, act decisively, and recover effectivelyIf your work involves protecting others, making critical decisions, or operating when the pressure is on, this podcast is for you. Subscribe to Optimising Human Performance to hear from the people who study, train, and live high performance in the most challenging conditions, and to learn how you can do the same.
