Fit Test 4 - The Plank.


Test 4 - The Plank - Get the stopwatch ready...

on your mobile phone or watch, get into position and hit start and hold the Plank for as long as you can. As soon as your back starts to sag or hips drop out of alignment then the test is over and make a note of the time you held a perfect position for in the corresponding cell in your stats sheet.
