Your body rebuilds itself at a rate of 330 billion cells every single day. That’s about 1% of all your cells. In 80-100 days, you’ve essentially rebuilt most of your body at the cellular level.
But here’s what makes this mental: the quality of those replacement cells is entirely dependent on what you’re doing right now. Every training session, every meal, every sleep cycle is literally programming the blueprint for your future physical self.
Elite athletes and fitness enthusiasts who train consistently aren’t just getting fitter; they’re building a fundamentally different organism at the cellular level compared to their sedentary counterparts. The mitochondrial density (energy-producing units in cells), capillary networks (tiny blood vessels), and muscle fibre composition are all being rewritten.
Most people have no idea that their body constantly rebuilds itself, and they’re doing it with terrible instructions. We’re writing code for our own biological software, whether we know it or not.
What gets me is that we’ve known this for decades, yet the fitness industry is still flooded with nonsense. With the correct information, each of us can take control of this process.
