PLANK
Begin in a plank position with your elbows positioned directly under your shoulders, forming a straight line from head to heels. Engage your core and lower down onto your forearms. Hold this position for 60 seconds, maintaining a straight body line. If holding for a full minute is challenging, break it down into 5 to 10-second intervals with 5-second rests. Keep your hips level and avoid sagging or arching during the exercise.
