You can attempt increasing the difficulty of the exercise by moving to a straight-arm plank, which is also referred to as a full plank. This will help you build up your strength.
With your hands directly beneath your shoulders and your knees slightly behind your hips, begin on all fours with your hands in this position.
As you raise one knee at a time off the ground, press your hands into the ground and continue to do so. To ensure that you are in a straight line from your heels to your head, straighten both of your legs. It is important that your body appears as though you are performing a pushup in an upward position. Make sure that your hands and shoulders are in the correct position, that your legs are powerful, that your feet are hip-width apart, and that your core is moving.
Continue to hold this position for at least thirty seconds, or for as long as you are able to keep your form correct.
