“I believe in finishing what I started,” says @oksanamasters on the sixth (and final) episode of Stronger Better Faster Stronger. “So if I start this race, that means I’m going to finish it. And if that means that today, I’m dead last, then that's okay. I know where to start tomorrow.” Later this month, Masters will head into her fifth straight Paralympic Games (that includes summer and winter), having competed in four different sports, winning eight medals along the ways. So she’s gotten pretty good at being in, and pushing through, what she calls the “pain cave.” If you want to hear how she navigates mental and physical barriers—including the simple counting trick she uses when her self-talk starts getting negative and why she approaches every race as just another day of training—visit the link in my bio.
