To stretch your quadriceps at the hip, the idea is to do the opposite movement to flexion, i.e., extension. You can perform extension moves at the hip while standing, lying on your side, lying prone (on your stomach) and kneeling. Even basic stretches done at a pain-free level where you can feel a small bit of challenge, and that are held continuously for approximately 30 seconds may translate to better posture and less back pain.
A few cancers in their early stages can be hard to tell apart from ordinary back pain — a bone cancer in the vertebrae, for instance — and these create a frustrating diagnostic problem. They are too rare for doctors to inflict cancer testing on every low back pain patient “just in case.” And yet the possibility cannot be dismissed, either! It’s an unsolveable problem.
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.​
