How to do the Half Sit-Up
Begin by lying flat on your back on the floor or a mat. Bend your knees and plant your feet about hip-width apart.
Place your hands behind your head or across your chest. Do not interlock your fingers behind your head as this can lead to pulling on your neck.
Engage your core by pulling your belly button towards your spine.
Slowly and with control, lift your upper body towards your knees, keeping a space the size of an apple between your chin and chest.
Raise yourself until your upper back is off the ground, roughly at a 30 to 45-degree angle, then hold the position for a second.
Slowly lower yourself back down to the starting position.
Repeat for the desired number of repetitions and sets.
