How to Do a 90/90 Hip Switch
Improves internal and external hip rotation.

To perform the 90/90 Hip Switch, sit on the floor with your legs bent at 90 degrees. Rotate your torso to switch sides while keeping your hips low and controlled. Focus on smooth, deliberate movements to effectively improve your internal and external hip rotation.
How to Do It
- Set Up: Sit on the floor with both legs bent at 90 degrees. Your right leg should be in front of you, and your left leg should be behind, creating a 90-degree angle at both knees.
- Engage Your Core: Keep your back straight and engage your core to maintain stability throughout the movement.
- Rotate to the Right: Begin by rotating your torso to the right, leading with your chest. Lower your right knee and lift your left knee off the ground, transitioning to the opposite side.
- Switch Sides: As you rotate, keep your hips low. Your left leg should now be in front, and your right leg should be behind.
- Complete the Move: Continue switching sides for the desired number of repetitions.
- Reps and Sets: Aim for 2 sets of 8 repetitions on each side, maintaining a slow and controlled tempo.
Muscles Worked
The 90/90 Hip Switch primarily targets the following muscles:
- Hip Flexors: Engages the iliopsoas and rectus femoris during the rotation.
- Glutes: Activates the gluteus maximus and medius as you stabilize your hips.
- Internal and External Rotators: Works the deep hip rotators, including the piriformis and obturator internus, enhancing rotation flexibility.
Common Mistakes
-
Mistake 1: Lifting Hips Off the Ground
Fix: Focus on keeping your hips low and grounded throughout the movement to ensure proper engagement of the hip muscles and avoid strain. -
Mistake 2: Rushing the Movement
Fix: Perform the exercise slowly and deliberately. This ensures that you maintain control and maximize the benefits of hip rotation. -
Mistake 3: Poor Posture
Fix: Maintain a straight back and engaged core to prevent rounding of the spine. This helps in stabilizing the movement and prevents injury.
Variations
-
Beginner: If you're new to this exercise, you can start by performing the movement without fully switching sides. Simply rotate your torso to the side while keeping one leg on the ground for balance.
-
Intermediate: Add a pause at the end of each rotation for 2-3 seconds to increase the challenge and enhance stability.
-
Advanced: Perform the hip switch with a resistance band around your knees to add extra resistance, engaging more muscles during the movement.
When to Avoid It / See a Clinician
If you experience any pain during the 90/90 Hip Switch, especially in your hips or lower back, it is crucial to stop and assess the situation. Consult a clinician if you:
- Have a history of hip problems or injuries.
- Experience persistent pain that does not improve with self-guided exercises.
- Are unsure about your form and its impact on any existing conditions. LegLike can guide you in developing a safer routine for your lower body, but it does not replace professional medical advice.
Sets/Reps/Tempo Guidance
For beginners, aim for 2 sets of 8 repetitions on each side, focusing on a slow tempo of about 2-3 seconds per rotation. This allows you to build control and strength gradually.
Incorporate this exercise into your routine to enhance hip mobility and overall lower body function.
