Ancestral wilderness skills have an innate ability to deepen the Father-Son connection like nothing else. During this custom Father-Son Wilderness Program, we'll make fire by friction, build and sleep in natural shelters, learn traditional hunting and gathering techniques, and track wild animals. Primitive wilderness survival isn't a "Man vs. Wild" scenario, it is an opportunity to build a deep relationship with the Earth. As you and your son do so, you'll find that your relationship with your son deepens in powerful ways. Click here for all details and to register.

Exercising In The Heat vs. Sauna Training Whole Doods: Ben talks a lot about Cold Thermogenesis and using saunas for fitness and health but what about just exercising in a hot location. He lives in Sierra Leone and when he works out, it is like he is always in a sauna and his heart rate is just jacked immediately and he sweats like a pig. Is he getting any added benefit by combining his hot environment with working out? In my response, I recommend: -This podcast on How To Use Heat Exposure Should You Use Colloidal Minerals?
