I was doing just about 2 minutes on planks when I started intermittent fasting in January 2019. And I was not regular at it.
I looked at planks again, just a few days back when I stopped my practice to do 30 push-ups in one go, due to a slight niggle with the shoulder.
I was seeing better stamina and endurance with several kilos down on weight and was recording minutes 2.30, 2.45, 3, 3.30, 4.
And today I was on plank position for over 5 minutes. That’s a milestone.
