Flexors are flexible muscle tissues that help a person stretch and move. The muscles that help you lift your knee toward your body and bend at the waist are known as the hip flexors. These muscles are located around the upper and inner things and pelvic region. Keeping the hip flexors strong is particularly important for active people and athletes.
A sedentary lifestyle can lead to having weak and tight hip flexors as they are always in the shortened position. Tight hip flexors can lead to a limited range of motion, poor posture, lower back and hip pain, and even injuries. These muscles need to get a workout when you are standing and doing movements such as raising your leg to climb stairs, run, or ride a bicycle.
