Primary Muscle Group: Rectus Abdominis
Muscle Groups Worked in This Exercise: Rectus Abdominis and Obliques
Preparation: To perform a prone bridge, kneel down resting upon your forearms and knees. Draw your stomach in and up while keeping your back flat, then hold this position for thirty to sixty seconds. Ensure you don't flex or extend your spine, but rather hold a neutral spine position throughout. You should feel a burning sensation deep in your stomach, this indicates you are doing the exercise correctly and working the correct muscle. Once you can do ninety seconds perform the exercise off your forearms and toes, so there is a straight line formed from your body running from your shoulders down to your feet.
Breathing: Breath out on the contraction of the muscle and breath back in on the way back to the start position.
Execution: To make the exercise harder still, you can decrease the base or points of support. Try to hold the same position but raise one foot of the ground. If you can do this, raise one foot and the opposite arm so you're only resting on diagonal opposite arm and leg.
