I'm currently an ms1. We had our first pft at the beginning of the month and I passed with a 260. I maxed push-ups, did well on the run, but barely passed my battalion's standard (70 pts) for not being on remedial for the sit-ups. What are some good workouts to improve sit ups? I've been doing unassisted sit ups, crunches, planks, and other stuff to improve but I don't think I'm seeing much progress. Thanks for your help.
