The 30 Day Plank Challenge follows in the footsteps of the Squat Challenge, and will send your core strength through the roof!
In this advanced challenge you follow the original 30 Day Plank Challenge rules until the final day. On the final day (day 30), rather than completing 5 minutes of plank you have to do as long a plank as possible! The winner of the contest is the person who completes the full 30 days and scores the longest time on the final day! - Good Luck.
