Adding In and Outs to your fitness program can be an effective way to build a strong midsection. The muscle groups in your core are important for stability, posture, and balance. Keeping them tight can prevent back injuries. Increasing your core strength can also improve functional movements. If you have a health condition, it’s a good idea to consult a doctor before starting a new exercise program.
What are in and outs in Crossfit?
During an in and out abs exercise, the rectus abdominis and transverse abdominis are the main muscles targeted. The rectus abdominis is the muscle that runs vertically through the front of your abdomen. It works alongside the psoas major and the iliacus major. Together these muscles work to flex your hips.
The transverse abdominis is the deepest muscle in the abdomen. It is responsible for controlling trunk movements and flexing the hips. It also helps to maintain an erect posture. The transverse abdominis can become weak over time and can cause back pain.
You can do in and outs from a standing position or a kneeling position. You can also do it with your hands at your side. You can also do a crunch version of the exercise.
In and outs are an easy and effective workout. They will tone and shape your lower abs, while also improving your definition of your stomach muscles. They are also good for high intensity interval training. They can be done at home and don’t require any equipment.
