I'm all for crunches, sit-ups, and planks if you want them, but there are other ways to build a strong core that don't involve them. This includes functional compound exercises that build better balance, stability, and power by recruiting multiple muscles, all firing together.
So let go of traditional ab workouts just for now, and give today's workout a try. The moves will still challenge those all-important core muscles, the ones you need to move well without injury, but you'll also work some other big-hitter muscles as well.
