Hugo and Ross Turner are twin brothers and professional adventurers. I first discovered them when I came across their various diet and fitness experiments, in which they have studied the differences between a vegan vs. omnivore diet, weighted vs. body weight gym programs, animal protein vs. plant protein for muscle gain, and a 20-minute vs. a 40-minute gym program to discover if 40 minutes actually offers twice the benefits (you'd be surprised at the results, which we discuss in this podcast!). In 2007, Hugo narrowly missed paralysis after breaking his neck in a diving accident. In the mix of emotions that followed, a drive emerged to pursue their passion for exploration, anchored by three values: purpose, discovery, and always doing it together.
