Most people in the fitness world are used to moving with friction. They think that grind is normal, but it is really just the result of poor mechanical leverage.
Over time the body starts pumping out hormones to mask the pain from that friction. And when people chase that feeling again and again, it turns into an exercise addiction built on dysfunction, not health.
FP training does the opposite. FP practitioners confront the friction, find its source, and train in a way that actually matches human biology. As you improve the FP First 4, you reduce the internal drag in your system and move with better mechanical leverage.
Less friction. Less pain. More efficiency.
That is what makes movement sustainable.
