How to do the Floor Seated Side-To-Side In-Out Leg Raise Crunch
Positioning:
Start Position: Sit on the floor with your legs extended in front of you. Lean back slightly while keeping your back straight. Your hands should be placed slightly behind you for support.
Body Position: Keep your legs elevated a few inches off the ground and bent at about a 45-degree angle. Your feet should be together.
Movement:
Crunch In: Engage your core muscles and pull your knees towards your chest while leaning back a bit more. Keep your feet together as you draw your legs in.
Move Side-to-Side: From the crunched position, rotate your torso to the right while extending your legs to the right side. Return to the center and then rotate your torso to the left side while extending your legs to the left side.
Repeat: Continue to alternate side-to-side movements, keeping your core engaged and maintaining control throughout the exercise.
Tips for Beginners:
Make sure to breathe throughout the exercise; exhale as you crunch in and inhale as you return to the starting position.
If lifting your legs is too challenging, you can keep your feet on the ground until you build enough strength to elevate them.
Focus on controlled movements rather than speed to maximize the effectiveness of the exercise.
