Plank with shoulder taps works core stability by resisting rotation.
In a high plank on your hands, arms extended, feet slightly apart for stability.
Lift one hand to touch the opposite shoulder, put it back down, then switch sides, slowly.
The pelvis must not sway: spread your feet wider if it is difficult.
