Don't hold your head in your hands. Generally speaking, sit ups put your hands behind your head and your hands behind your head. It is easy to bend your back, compress the lumbar intervertebral disc, and damage your spine. It also reduces the workload of abdominal muscles. The right way is to cross your hands in front of your chest, or put your hands to your ears. When you sit up, you should let your abdomen work, not your arms.
When cooperating with breathing practice: exhale in the state of rising (exerting) and inhale in the state of retreating. Static state, such as when maintaining a 45 degree angle, maintain normal chest breathing, do not hold your breath. Usually: abdominal breathing helps to tighten the transverse abdominal muscles, feel the abdominal cavity inward and upward when inhaled, fully inhale and then exhale deeply. When you are sitting, standing or walking, you can consciously take abdominal breathing and form a habit.
