The core muscles include the abdominal muscles, back muscles, the glutes, and the muscles around the pelvis. Strong core muscles make it easier to perform many movements and help maintain posture.

The plank exercise involves keeping the abdominal muscles while continuing to breathe regularly. Hold the plank position for up to 1 minute and then do six repetitions on each side where you move the right and then left arms into position for a push-up followed by repetitions using the left and then right arms.
