Zone 2 and breathless intervals: how experts build the cardio week
Huberman's fitness tools start from 150 to 200 minutes of zone 2 cardio a week and add harder sessions, Rhonda Patrick swaps 10,000 steps for 10 breathless minutes, Stacy Sims tells women to polarize their training and sprint briefly, and Vonda Wright's routine pairs walking with sprinting. Seeing how each of them combines easy and hard work helps a reader spend limited cardio time well.
Bones need load: DEXA scans, osteocalcin and lifting against bone loss
Peter Attia recommends DEXA scans and tracking bone mineral density, Stacy Sims and Vonda Wright treat strength training as bone medicine, Sharon Malone covers bone loss around menopause, and Huberman explains how loaded bones release osteocalcin that reaches the brain. Bone is living tissue that answers to mechanical stress, so the case for lifting covers the skeleton as well as muscle.
Women are not small men: training and eating differently after 35
Stacy Sims, Mary Claire Haver, Vonda Wright and Mel Robbins' guest argue that women should lift heavier, eat enough protein and adjust training through perimenopause instead of defaulting to endless cardio. This counters decades of fitness advice designed around male physiology.
Fed or fasted training? Fung, Sims and Galpin split on empty-stomach workouts
Jason Fung argues that fasting is compatible with performance, even for athletes. Andy Galpin says fasted cardio doesn't boost fat loss, and Stacy Sims and Mel Robbins' guest say women in particular should eat before they train. Knowing where each position comes from, and who it applies to, keeps you from copying a protocol built for someone else's body.
