This challenge is guaranteed to be exactly that...CHALLENGING! We don't expect most of you to finish it on the first attempt but we encourage you to regularly work on it until you do! For those of you who do it on the first try, you may want to look into training for the plank world record of 1:20:07 (hrs:mins:secs) and give the great George Hood a run for his money!
Faça este treino com o melhor equipamento de exercício. Recomendamos o uso de um monitor de frequência cardíaca de tira peitoral bluetooth ou um smartwatch para mais otimização de treinamento e acompanhamento de desempenho.
