If you are prepared to assume a plank position without any adjustments, the forearm plank is an excellent approach to experience the burn more intensely.
After lying down on the floor, position your forearms so that they are directly beneath your shoulders.
Raise your torso off the ground in a slow and controlled manner by applying pressure to your knees and forearms. During the process of raising yourself up, make sure to keep your neck and spine in a neutral position.
You should make sure that your body is in a straight line by tucking your toes under and lifting your knees.
Maintain this position for twenty to thirty seconds, gradually increasing the time until you reach one minute or more. In accordance with Guinness World Records, the forearm plank that was held for the longest period of time was nine and a half hours (2)!
To ensure that your neck is in a neutral position, it is recommended that you let your sight to fall toward your mat, which is approximately one foot in front of you.
