Everything I Thought About Exercise Was Wrong

For a long time, I believed a set of things about exercise that I never really questioned, because they were repeated so consistently they felt like settled facts. Stretch before you work out or you'll get hurt. If a workout doesn't leave you sore, it didn't count. Squats and running wreck your knees. Older adults should avoid intense training. I believed all of it — until I actually looked at the research behind each claim individually, and found that a surprising number of them don't hold up, or hold up in a much more limited, conditional way than the confident advice usually suggests. This episode walks through what I got wrong, one claim at a time. We cover static stretching before workouts and why dynamic warm-ups generally serve injury prevention better. We cover "exercise snacking" research showing short bouts of activity genuinely count, and why soreness isn't a reliable measure of a good workout. We debunk the idea that squats, running, and deadlifts are inherently bad for your joints — the research actually points the other way for most healthy people. We address the myth that HIIT is universally superior to steady-state cardio, and the surprisingly harmful belief that older adults should avoid vigorous exercise. We look at how accurate fitness trackers actually are, why you don't need a gym to build real strength, why rest days aren't a lapse in discipline, and myths about exercise timing, sport specialization in kids, "perfect form first," swimming and cycling for bone health, and oversold sports drinks and pre-workouts. We close with the psychology of exercise motivation — why framing exercise as punishment actually undermines the results people chasing that framing are hoping for.
