How to do the in and out exercise?

Let’s go through some steps required to perform the in and out exercise.

First, you must sit straight and place your arms at your sides. Next, your legs should bend forward, and your feet must be together on the ground right before you.

Second, you must tighten your core and keep your back straight. Do it as you elevate your feet from the ground. Next, bring your knees up towards your chest. This will place you in the “in” body position.

Third, lean back gently and keep your spine straight as you straighten your legs. Treat the movement like a balancing act between the legs and the upper body. Your bottom needs to be the only thing touching the ground.

Fourth, when your shoulders come close to the ground, you must pause and make sure only your bottom touches the ground. This will be the “Out” position of the exercise.

Fifth, lift your shoulders and legs back to the “in” position. Again, remember to keep your core tight as you move.

Repeat the “out” and the “in” movements to work your core.

If you experience pain or cannot keep your core tight to control the movement, you need to pause and rest longer. Consider some easy variations to prepare for the core exercise and to complete the training.
