The illiacus attaches on the upper portion of the femur and begins on the inside crest of the illium (inside of the pelvis), where the psoas attaches all the way through the transverse processes of the lumbar spine, even binding into the discs directly. The rectus femoris begins at the base of the anterior superior illiac spine, and attaches all the way down to the knee cap, whereas the sartorius starts in the same place as the rectus femoris, but attaches on the medial aspect of the knee, blending with the MCL and portions of the hamstrings.
How to: Sit down with your knees bent and feet flat on the floor in front of you (a). Place your right ankle on top of your left thigh and flex your right foot (b). Put your hands behind your body, fingertips facing away from your body and begin to press your hips toward your heels until you feel a stretch through your outer left hip. Keep your back tall and chest open (c). Hold for six to eight breaths, then repeat on the other side.
Those are some great stretches! I own a personal training studio in Severna Park, Maryland. Majority of my clients have physical limitations – so it’s important for them to stay flexible. I send these to my clients and even do these exercises for myself. I highly recommend these stretches to anyone, even people without physical limitations. I love the fact these are actually videos and not just stretches because it’s so much easier for people to figure out how to perform the stretches. You guys are the real MVP!
Hey Martha! Thank you so much for your comment! You’re right, if you’re flexing the hip it’s hard to stretch it! The last three you mentioned are so helpful for focusing on the adductor group, although yes, they aren’t helping stretch the rectus femoris in those positions. I was trying to include a variety of stretches to include every hip flexor muscle. I’m very curious about the lying hip flexor stretch now, though. It’s been a go-to with every trainer I’ve worked with, and I’ll have to look into this more. What are your favorite hip flexor stretches for patients? Thank you!
The better you understand anatomy and biomechanics the more effectively you can program exercise for clients who need correction and/or to restore balance between the right and left sides of the body. There are 11 muscles that flex the hip joint. Each of these muscles also has other abilities for movement. For example, tensor fasciae latae also internally rotates the hip and abducts it. Whereas sartorius abducts but externally rotates the hip. The muscles in the human body all overlap each other in their abilities, making it the machine of many movements that it is.
The tensor fascia latae originates from the front of the hip and inserts into a long fibrous band called the iliotibial tract on the outside of the thigh. This muscle supports hip flexion, leg rotation and outward movement of the thigh. Tensor fasciae latae syndrome, also known as iliotibial band syndrome, is an inflammatory condition that most commonly develops in distance runners. Inflammation arises when the muscle and band repetitively rub against the outer head of the thighbone, frequently causing a painful snapping sensation in the hip. Treatment typically involves anti-inflammatory medication and hip-strengthening and range-of-motion exercises. Good running shoes can help prevent tensor fasciae latae syndrome by promoting proper hip, knee and ankle alignment.
