The truth is that I have been training my abdomen these last days to prepare myself and to have better resistance when performing the abdominal plank, I have prepared myself a little bit, I am very happy because last time it was 2:28 and this time I was able to hold 3:05 improving my endurance a little more than 30 seconds. For next time I will try to get the 4 minutes, it will be hard, but I can do it.
