Take a deep breath and brace your core by drawing your navel toward your spine to prepare for the crunch movement.

Lower your torso by moving backward and downward in a controlled manner, allowing the abdominal muscles to lengthen and extend fully.

Contract the abdominal muscles by flexing the spine and bringing the ribcage toward the pelvis in a crunching motion, then return to the starting position with control.
