The core area is the centre of gravity and stability for all bodily movements.

Core strengthening exercises are done to train the core muscles and strengthen them and work in harmony for better body balance, stability, and movement. Core strengthening exercises include crunches, plank, L-sit, sit-ups, push-ups etc
