Women 40+: How to Structure Your Week for Strength, Energy & Longevity

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-guideA BIG thank you to our sponsors who make the show possible: • Stride Shownotes for Stride should say: 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.
