Will and Ralf are putting their physical and mental strength to the test. They meet the World's Strongest Woman, learn calming Buddhist practices and challenge themselves in an explosive Hostile Environment Training drill.

Will & Ralf are ageing - but should they fight it? After painful facial treatments, they experience physical frailty and falling over in ageing suits. Keen to show they've still got it they challenge themselves as strippers.

Will & Ralf are pushing themselves to their limits. Will hates dirt, so a mud assault course is torture and a day at a Man Camp brings discomfort and big emotions. On a clifftop, can they come together for one big final leap of faith?
