Tony Robbins has a bit of a cult following to say the least. Love him or not you can’t say he has not been a consistent figure in the self help movement for decades. It is also impossible to deny that Robbins is anything but the picture of health and energy despite nearing the age of 60. He still goes onstage for up to sixteen hours at a time displaying high energy and vitality to massive crowds. Tony Robbins has been a lifestyle and health hacker since before it became trendy and ubiquitous.

Daily morning sauna use has been such a fixture in his routine that he has saunas (with cold pools) installed in all seven of his homes. His routine involves a vigorous workout followed by an equally vigorous sauna and cold pool session. Billy Beck III is the full-time personal trainer to Tony Robbins and has been the one who recommended the practice of daily sauna as an extension to Tony Robbins workout for cardio reasons. He told Business Insider he finds it “improves circulation and wakes your ass up.” Rather than a long relaxing sauna session he prefers a short very hot sauna of 100 F or slightly hotter.
