Plank Bridge - Isometric Strength

In this lesson, you will learn how to perform a plank bridge. This is an isometric exercise for the core area, where you start in a push-up–like position with your forearms on the floor. By adjusting the position of your hands, you can focus more on the arms, shoulders, chest, or back.

Description: Plank Bridge – Isometric Core Strength

Lie face down on the ground and place your elbows directly under your shoulders. Your forearms should be flat on the floor and parallel to each other. Your hands can either be clenched into fists or open — it doesn’t matter.

The key to this exercise is not to hollow (relax) your back. In fact, slightly round your back and keep your abdominal muscles tight throughout. You can raise your head slightly, but it’s better to keep the upper part of your spine — including your head — parallel to the floor.

The further your feet are from your elbows, the more difficult the exercise becomes.

Hold this position for 10 to 30 seconds, or until you can no longer maintain a straight back. If your back begins to hollow, the exercise loses its effectiveness.

Trainer Advice: Plank Bridge – Isometric Core Strength

Different Variations:

  • While keeping your back slightly rounded, you can adjust the position of your arms:
    • If your elbows are under your abdominals (angle < 90°), you will also engage your shoulders.
    • If your elbows are in front of your shoulders (angle > 90°), you’ll work your back muscles.
    • If you separate your forearms wider than shoulder width, you’ll give your chest muscles a stronger workout.
    • To focus on your arms and back, try lifting your elbows slightly while keeping your hands on the floor.

This is an isometric bodyweight exercise — there’s no need to add extra weight to your back. If you need a greater challenge, simply hold the position longer or switch to a different exercise.

Breathe slowly and with control throughout the movement.
