How to do the Side-To-Side Knee-Tuck
Begin in a seated position on the floor with your legs extended in front of you and hands resting on the floor slightly behind your hips for support.
Lean back slightly and engage your core muscles to lift your feet off the floor, finding your balance on your sit bones.
Keeping your hands on the floor for stability, twist your torso to the right, bringing your knees towards your right elbow while maintaining a strong, engaged core.
Pause briefly in this tucked position, ensuring your abdominal muscles are fully engaged.
Untwist your torso and extend your legs back to the center, not allowing your feet to touch the ground.
Now twist to the left side, bringing your knees towards your left elbow, mirroring the movement on the opposite side.
Continue this side-to-side movement for the desired number of repetitions, keeping the movements controlled and consistent.
Make sure to breathe normally throughout the exercise, exhaling as you tuck your knees in and inhaling as you return to the center. Keep your movements smooth and avoid using momentum to swing your legs. Focus on using your obliques to perform the twisting motion.
Remember, this exercise requires coordination and balance, and it is important to maintain proper form to prevent any strain on your back. If you're new to this exercise or if you have any back issues, proceed with caution and consider consulting a fitness professional.
