ISOMETRICS FOR HIP MOBILITY - The concept of the 90/90 is built around a shin box movement exploring rotation but that thought can be added in many loading strategies. Here are a couple favorites currently looking at strengthening the hips, improving hip mobility and being strong in big ranges of motion.
Hip Flexor Plank, think of this as the name suggests. We can add weight on the back and program for time or breaths under load here.
90/90 Copenhagen, short lever which I think allows us to focus more on the hips getting the lift while pulling the front leg up into flexion.
Single Leg Glute Bridge, holding the isometric while not allowing the pelvis to tilt laterally. Also emphasis on here getting the hip into extension without extending through the lower back.
FFE Split Squat, elevating the front leg to get a little deeper into hip flexion while holding the isometric. Big emphasis on staying in a posterior pelvic tilt throughout the hold.
Give these a try starting our holding each movement for 10 seconds each for 2-3 sets progressing to 30 seconds for each hold to improve hip mobility, get out of hip and back pain if mobility is a limitation and getting stronger in the hips.
