Plank

Start on your hands and knees. Place your forearms on the floor with your elbows directly under your shoulders. Extend your legs back, one at a time, to lift your hips off the floor, forming a straight line from your head to your heels.

1. Brace your core and squeeze your glutes.
2. Hold the position for the desired duration.
3. Breathe steadily throughout the exercise.

• Keep your back flat.
• Don't let your hips sag.
• Maintain a neutral neck by looking at the floor.
• Squeeze your glutes.

• Hips sagging toward the floor.
• Piking hips up too high.
• Tilting the head up or down.
• Holding your breath.
