If you’ve ever felt tension in the front of your hips after sitting for a long time, struggled with back pain, or had trouble touching your toes, your hip flexors could be the culprits.
These often overlooked muscles play a vital role in posture, climbing stairs, running, and more. However, sedentary modern lifestyles and repetitive movements can leave them shortened and tense.
What are the hip flexors?
The hip flexors are a group of muscles primarily responsible for lifting the knees and bending at the waist.
They include:
• Iliopsoas: The engine of hip flexion, a combination of two muscles — the iliac and psoas — that together connect the pelvis, lumbar spine (lower back) and femur (upper leg bone).
• rectus femoris: A quadriceps (thigh) muscle that spans both the hip and knee, serving as a primary hip flexor.
• Sartorius: The longest muscle in the body, running from the hip to the shin and assists with hip flexion and external rotation.
• tensor fasciae latae: Located on the outside of the upper thigh, it works with the rectus femoris to flex the hip and contributes to hip abduction and internal rotation.
When any of these muscles are tense, the tension pulls the pelvis forward, tilting it into an anterior position, which places compressive pressure on the lumbar spine and knees, which can lead to hip immobility, back strain, and leg problems. knees and more. Because these muscles connect the upper body to the lower body, tight hip flexors not only cause discomfort, immobility, and increased risk of injury, but they can also lead to changes in posture, gait, and balance.
Tightness in the hip flexors is caused by both overuse and underuse. Repetitive motion from sports and activities such as running, cycling, and climbing stairs can shorten and strain the hip flexors, while excessive sitting leads to the same result—but with additional weakness.
