Positioning
1. Starting Position:
Begin seated on the floor with your legs bent.
Position your right leg so that your thigh is parallel to your body and your shin is perpendicular to the ground, with your foot flat on the floor.
The left leg should be positioned the same way, with the thigh parallel to the body and the shin perpendicular. Both knees should be at 90-degree angles.
Movement
Shifting Position:
While keeping your torso upright, slowly drop your knees to one side, allowing your right knee to come down towards the ground. Keep your left foot in the same position.
You should feel a stretch in your hips as you maintain the 90-degree angle in both knees.
Transition:
Hold this position for a few seconds to engage the stretch.
Then, gently shift your legs to the opposite side, bringing the left knee down and keeping the right foot in the same position.
This back-and-forth movement is the main motion of the exercise.

Keep your back straight and avoid leaning to one side excessively.
Move slowly and focus on maintaining control throughout the exercise.
Repeat the side-to-side movement for a set number of repetitions or a specified timeframe.
