Discover how changing your breathing can transform your running performance, recovery, and overall enjoyment of the sport. In this conversation, Patrick McKeown (author of The Oxygen Advantage) interviews David “Jacko” Jackson, former professional rugby player, strength & conditioning coach, and author of “Breathe Smarter, Run Stronger” (out March 12, 2026). They explore: How Jacko accidentally knocked over a minute off his 5K time in four weeks just by changing his breathing—not his training volume Why most runners (from recreational to elite) are leaving performance on the table by ignoring breathing The difference between breathing rate vs. tidal volume and why deeper, slower, more efficient breaths can reduce perceived effort and breathlessness How nasal breathing improves oxygen delivery, running economy, and recovery—and when it makes sense to switch to mouth breathing at higher intensities The role of the diaphragm, rib cage mobility, and posture in breathing efficiency and running mechanics Why CO₂ tolerance, air hunger, and breathing muscle effort are key levers for controlling pace and effort How breath holds and “anaerobic” breath training can boost repeat sprint ability and lactate handling in team and endurance sports Practical ways Jacko integrates breathing into daily life, sleep, easy runs, hard sessions, and recovery Whether you’re a casual jogger or a competitive athlete, this episode shows how training your breath can help you run faster, feel better, and recover quicker—without just adding more miles. #oxygenadvantage, #breathwork, #runningperformance, #nasalbreathing, #endurancetraining, #runnersofinstagram, #marathontraining, #5ktraining, #vo2max, #diaphragmaticbreathing, #functionalbreathing, #sportsperformance, #recovery, #mentalhealth, #asthma, #rugby, #strengthandconditioning, #breathingexercises, #runningtips, #runstronger

Can strength training, breathwork, and self-awareness completely transform a life shaped by bullying, low confidence, and an eating disorder? In this powerful conversation, professional strongwoman and strength & performance coach Sandra Bradley shares how she became one of the world’s leading strongwomen and how tools like Oxygen Advantage® breathing, mindfulness, and process-focused training have shaped her body and mind.

We explore:

- How Sandra went from watching World’s Strongest Man on TV to becoming a top strongwoman athlete

- Her journey from eating disorder, bullying, and dissociation to self-acceptance and inner strength

- Why lifting odd objects and historical stones (including the famous Fullsterkur stone in Iceland – 154 kg) builds real-world resilience

- How Oxygen Advantage style breathing, cold exposure (ice baths), and mindfulness support nervous system regulation and recovery

- The difference between ego-based goals vs intrinsic goals in training and life

- How to use strength sports, breathwork, and presence as tools for self-confidence, emotional regulation, and personal growth

If you’re interested in Oxygen Advantage breathing, mental performance, strength training, ADHD, burnout recovery, or how to build unshakable confidence, this episode is for you.
