Half of them did stability exercises, beginning with planks, side planks, and bird dogs, holding each for 10 seconds at a time. They did 5 sets of each exercise, starting with 5 reps (10-second holds), then 4, 3, 2, and 1.
When performing Plank challenges remember there is no real benefit of holding a plank for longer than 1 minute. You will not improve strength by holding statically for too long. Testing that balance by adding dynamic movements will have more effect. In my view, a plank is an exercise not to be missed off your training plan.
