You can hit the gym four times a week and still be quietly undone by your chair. That's the uncomfortable thesis behind what's been called "the sitting disease," and in this episode, Pete Wright sits down (ironically) with strength coach Srdjan Injac to walk through exactly what eight to ten hours of daily sitting does to the human body.

The conversation moves region by region. The thoracic spine stiffens. The diaphragm gets compressed and breathing goes shallow. The hip flexors tighten until the glutes — which are supposed to be one of the strongest muscles in your body — essentially clock out. Lower back pain gets blamed on the back, when the real problem is everything around it. And then Srdjan goes inside, where the sitting disease gets genuinely uncomfortable: glucose handling declines, insulin sensitivity drops, and within sixty to ninety minutes of sitting, an enzyme called lipoprotein lipase — the gatekeeper that pulls fats out of your bloodstream — falls off a cliff.

The payoff is practical. Stand up every hour. Take walking meetings. Get the steps in, not because anyone needs to see them but because your metabolism needs the movement. And when you do get to the gym, expect the work to be uncomfortable in the right way — split squats that finally stretch what's been flexed all day, exercises that activate muscles you forgot you had. The mindset shift here is the whole episode in one sentence: hurt is not broken. Hurt is on the mend. Movement isn't a workout you complete and check off. It's a feature of your day.

If you've ever wondered why you're doing everything right and still feeling stiff, sluggish, and slowly heavier — this episode is the answer, and the way out.
