At the end of my planking for 30 days challenge, I managed to go from a maximum time of 1:30 to 2:46! I couldn't hold for another second. Unfortunately didn't crack the 3min mark, but getting an extra 1:16 on my original time is really awesome! Happy with my results and progress over just 30 days of doing planks and some other core exercises.
