Double-Knee Up Twist

1. Start by standing with your feet shoulder-width apart and placing your hands behind your head, elbows flaring out to the sides.

2. Engage your core muscles to stabilize your spine.

3. Lift your right knee up towards your chest while simultaneously twisting your upper body to the right, aiming to bring your left elbow towards the raised knee.

4. Return your right foot to the floor and your upper body back to the starting position.

5. Lift your left knee up towards your chest while twisting your upper body to the left, aiming to bring your right elbow towards the raised knee.

6. Return to the starting position and continue alternating sides for the desired number of repetitions.

7. Move in a controlled manner to maintain proper form and maximize engagement of your abdominal and oblique muscles.

8. Remember to breathe smoothly throughout the exercise, exhaling as you twist and inhale as you return to the starting position.

Safety Note: Keep the motion controlled, and avoid jerking movements to prevent strain on the lower back. If you have any pre-existing back issues, proceed with caution and consider consulting with a fitness professional.
