Crunches are not the way to go as they put too much pressure on your neck and lower back. That's why they are one of the exercises doctors will never do.

Back pain can occur from too much flexion in the spine and from the many repetitions.
Personal trainers always recommend planks and burpees, but, let’s face it, they are too hard. There has got to be another, preferably, easier way, right? Fortunately, yes.
