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!
Doe deze workout met de beste trainingsapparatuur. We raden aan om een bluetooth borstband hartslagmonitor of een smartwatch te gebruiken voor meer trainingsoptimalisatie & prestatietracking.
