You can tackle plank tucks in many ways, but whatever approach you try, they’re a killer full-body exercise. I added to our ever-growing plank challenge repertoire at Tom’s Guide and did 70 reps a day for one week.
If plank tucks haven’t entered your workout regime before, the exercise works your shoulders, arms, core muscles, hip flexors, lower back and legs. To do plank tucks, you’ll start in a plank position, jump both legs between your hands, then jump back again. But several variations fire up your core even more.
