Illustrated tutorial on plank knee to elbow crunch (plank knee to elbow crunch)

Target exercise area: Abdomen

< p>Starting position: Facing the ground, bend both forearms downward and close to the supporting ground. The palms should be tightened and placed directly under the shoulders. Bend your toes slightly and tighten your abdomen so that your belly and belly button feel stretched toward your spine. Straighten your body but keep your neck and spine relaxed. Imagine you are a plank of wood.

Action essentials: Tighten the abdomen and keep the back straight. Then lift the left knee while retracting the right elbow, trying to make the knee joint and the elbow joint contact. At the same time, keep the other leg of both legs straight, and the abdomen is always in a tightened state, so that the elbow joint of the other side can be lifted. Touch the knee on the other side, return the side of the bent leg to the straightened state, inhale during the tightening process, breathe the moment the elbow joint touches the knee, then cross and repeat the exercise

Tip: Keep your back straight at all times, do not bend over,
