Description
T-Cross Sit-up is a variation of the classic crunch exercise that targets the abdominal muscles and obliques. In this exercise, you create a T shape by extending your arms as you rise up, which engages the upper body muscles more. It is an effective exercise for strengthening the core region and also improves balance and coordination. It works both the straight abdominal muscles and the side abdominal muscles. It can be easily performed on a flat surface and requires no equipment. When performed with proper form, it can help prevent lower back pain.
