教练提示
姿势要点
Place your hands lightly behind your head or crossed over your chest. Avoid pulling on your neck or using your arms to lift your upper body, as this can cause neck strain. The power should come from your abdominal muscles, not from your neck or arms.
As you lift your upper body, focus on contracting your abdominal muscles. Exhale as you crunch up and inhale as you lower back down. This should be a slow, controlled movement - don't use momentum to jerk your body up and down.
Remember that a crunch is not a full sit-up. You should only lift your head, neck, and shoulders off the floor. Going too
