For this, our 50th episode of the NeuFit Undercurrent Podcast, I’m proud to welcome our biggest guest yet. Not just big physically, standing 6 foot 10 inches tall, but also big in the world of tennis. John Isner is the highest-ranked American tennis player in the world, has won dozens of professional tournaments, and holds the record for the longest tennis match of all time at over eleven hours long. It takes a special kind of resilience and determination to perform at that high of a level every season — and to continue doing it at age 36. Listen in as John describes how prioritizing his fitness and enhancing his recovery with the Neubie has enabled him to perform at the top level of his sport at an age where many of his competitors are declining or considering retirement.
