High Performance Health

Bill Campbell PhD, a body-composition researcher focused on fat loss, muscle and menopause, joins to unpack midlife changes. He talks about why some women gain fat during the menopause transition and the 2–3 year high-risk window. He explains why hormone therapy helps some but not all, how unnoticed drops in daily movement matter, the right protein amounts, and why lifting and sleep are crucial.

VO2 max is one of the strongest, most measurable predictors we have of longevity; and for midlife women, getting your cardio strategy right matters. In this episode, I break down the real truth behind the “HIIT vs Zone 2” debate, and show you how to use both in a way that supports energy, brain health, and long-term performance, including what Zone 2 training really improves, and what HIIT actually changes in your body. You’ll also learn how to programme cardio in midlife so you increase VO2 max without disrupting sleep, strength training, or your ability to recover. By the end, you’ll have a clear weekly framework to build cardiovascular fitness safely in midlife, even if you’re time-crunched, plus two science-backed interval workouts that reliably improve VO2 max. WHAT YOU’LL LEARN • Why VO2 max is a powerful longevity marker (and why it matters in midlife) • The difference between Zone 2 and HIIT (and what each one is for) • What Zone 2 builds (aerobic base, mitochondria, recovery capacity) • Why Zone 2 often “feels pointless” for high-achieving women (and what to do instead) • How HIIT improves VO2 max, insulin sensitivity, and metabolic health • The brain benefits of Zone 2 vs Zone 5 (BDNF, lactate, blood flow) • Why “more intensity” often backfires in midlife (sleep, stress, injury risk) • The progression hierarchy that protects your joints and results• How many HIIT sessions women actually need (and when it’s too much) • Two evidence-backed HIIT workouts: micro-intervals + the Norwegian 4x4 • A simple weekly template that works even with 30 minutes a day • How to combine resistance training + cardio in the same day for best results VALUABLE RESOURCES 10 Habits That Help Me Reverse My Biological Age (Free Guide) 👉 https://academy.angelafosterperformance.com/10-habits-guide A BIG thank you to our sponsors who make the show possible: Find out your biological age and how your daily habits are influencing it with DNA, bloodwork and microbiome testing with a Stride One membership - visit https://www.getstride.com/angela/ for 10% off.

Ari Whitten, natural health educator and mitochondrial researcher, explains how light and lifestyle shape cellular energy. He unpacks red and near-infrared light, device quality and specs, and why wavelength, irradiance and proximity matter. Practical talk on timing, masks vs panels, systemic benefits and safe dosing for recovery, performance and anti-aging.

Clear breakdown of rep ranges for hypertrophy, strength and endurance. The benefits of structured programs and volume are highlighted. Practical progression from bodyweight to bands to kettlebells for functional strength. Training approaches for menopause, including HIIT and heavier lifting, are discussed. Focus on preparing the body for everyday tasks like lifting children or carrying luggage.

Valter Longo, world-leading longevity scientist and director of USC’s Longevity Institute, explains what truly slows biological ageing. He contrasts biological vs chronological age. He reveals why extreme fasting or high protein can backfire. He describes the 5-day Fasting Mimicking Diet, why a 12-hour overnight fast matters, and the dietary patterns linked to long-lived populations.

Why midlife belly fat often reflects visceral fat and insulin exposure rather than a collapsed metabolism. Practical shifts covered include breaking up sitting with frequent movement, prioritising resistance training, using short HIIT sessions wisely, choosing fibrous whole-food carbs, and improving sleep and stress resilience.

Adam Parker, executive wellness and performance coach and Ideal Day podcast host, guides practical daily detox habits. He discusses why modern toxic load overwhelms natural clearance. Short, clear takes cover where toxins hide, a colon-first detox sequence, sauna and binder protocols, mineral replenishment, and controversial practices like coffee enemas.

They dig into workout timing for women, comparing morning sessions that target abdominal and visceral fat with afternoon training that boosts strength and neuromuscular power. Discussion covers hormones like ghrelin and how resistance work mobilizes belly fat. The conversation ends by stressing consistency and choosing a routine that fits your life.

Siobhan Mitchell, neuroscientist and mitochondrial health expert, explains why mitochondria do much more than make ATP. She covers mitophagy, mitochondrial biogenesis, and how hormetic exercise differs from chronic stress. Conversations include mitochondria’s role in immunity and inflammation, how NAD declines with age, and why brain energy and oestrogen changes matter for midlife cognitive fog.

Perimenopause doesn’t have to mean accepting brain fog as a norm. Learn how fluctuating hormones affect brain power and discover four biology-based strategies to sharpen your focus. Nutrition tips highlight the importance of protein and healthy fats for stable cognition. Higher-intensity exercise can boost mental clarity by promoting brain-derived neurotrophic factor (BDNF).
