Alternating Kneeling Arm Raise Plank

Get into a forearm plank position on your knees with your elbows directly beneath your shoulders and your core braced tightly.

Keep your hips level and squeeze your glutes to maintain a straight line from your knees to your head.

Slowly lift one arm straight out in front of you without letting your torso rotate or dip.

Hold the arm extended for a brief second, then lower it back to the starting position with control.

Switch to the other arm and repeat the movement for your desired number of alternating repetitions.
