Although they have never really been much of a staple in my program design, I have stopped doing any sit-ups and crunches with my clients. In the past, I have had my clients doing some stick crunches and medicine ball sit ups during my core routine (along with bridges, planks and quadruped exercises).

I had heard about other coaches taking them out of their programs, particularly Coach Boyle, and although I thought he made sense, I didn't feel I really needed to eliminate them since they were a small part of the program.
