The 2-point plank increases strength and stability throughout the core while also improving balance and coordination.
Position yourself with elbows and toes on the floor, keeping your elbows directly beneath your shoulders. Lift up your hips, forming a straight line from shoulders to feet. Brace your abs and squeeze your glutes.
Without allowing the body to rotate, simultaneously lift and extend one arm and the opposite leg until both are parallel to the floor. Return to the starting position and repeat lift with the other arm and leg.
Do not allow your torso or hips to rotate. Stay rigid.
Do not hike your hips high or sag the hips low during the plank.
