Extreme athlete Wim Hof shows eight celebrities how the cold can transform their lives forever through a series of unique challenges designed to help them overcome their fears. Living in a tented village in mountainous sub-zero temperatures, the celebrities including Gabby Logan, Patrice Evra and Professor Green face an array of extreme-cold challenges that will test them to their limits, both mentally and physically. From daily cold showers to ice barrel baths and swimming under a frozen lake, Wim Hof guides the celebrities through these unique tests using his signature breathing techniques, in the hope that they will reap the rewards of extreme-cold therapy and emerge happier, healthier and stronger. Each activity takes them closer to conquering the ultimate mind- over-matter challenge – leaping backwards from a 500ft bridge to the depths below.
