What Are Crunches?

The easiest way to think ofcrunchesis as a simplified and streamlined version of a sit-up.

Crunches specifically target just your abs, making them a fast and effective ab exercise.

Planks work your entire core, with particular emphasis on your abs, says Catudal.

When you plank properly, you engage and squeeze your abs, lower back, andglutes.

Beyond these muscles, the pull of gravity activates others.

However, no matter how many crunches you do, youll only work your abs.

“Planks are a safe isometric hold for most individuals with lower back problems,” says Andrew.

By performing proper form in a plank, aggravation can be mostly avoided.

Crunches won’t have as great an impact.

To be in the best shape it’s possible for you to be, both are beneficial.
