Former Bayern Munich striker Andre Schurrle has completed the 'Wim Hof' method. It is a technique that combines cold therapy with concentration exercises.
This practice is done in extreme sports such as climbing a mountain at very low temperatures with little clothing. This is how the former footballer has shown himself on his social media.
"The hardest mental and physical thing I ever did! The last minutes I couldn’t feel anything and I had to find something deep inside me to keep going! An experience that I will never forget! -19 degrees, 100 km/h wind in our faces, heavy snow and rain!
"What I learned…My body and I are stronger than I thought if I put my mind and soul to it I can do everything," Schurrle wrote on his Instagram account.
