The cross-legged twist will stretch the outside of your hips and part of your buttocks. Sit crossed-legged on the floor and then lift your right leg and place your foot on the outside of the bent left leg. Twist your upper body to look over your right shoulder. You can reach your left arm to the outside of your right leg to hold the stretch and place your right hand on the floor behind you for support. After 30 to 40 seconds, switch sides.
These issues tend to be more rampant in women because they generally have wider pelvises than men, Ali Kotek, M.A., A.T.C., P.E.S., a performance enhancement specialist and fellow endurance program manager at Athletico, tells SELF. So to keep the thighs vertical, rather than angled in toward each other, the outer hips have to be even stronger. That’s especially true for women who are bounding from one foot to the other as they run down trails and treadmill belts.
Back pain can suck the joy out of your days for week, months, even years. It can definitely be “serious” even when it’s not dangerous. I have worked with many truly miserable chronic low back pain patients, and of course the huge economic costs of back pain are cited practically anywhere the subject comes up. But your typical case of chronic low back pain, as nasty as it can be, has never killed anyone.
Apply the above concept to your hips. When you sit, your hips are in a "flexed" position. Therefore, the muscles that flex your hips are in a shortened state. You probably spend at least a third of your day sitting down. Think about how much time those hip flexor muscles stay shortened. A lot. Over time, they become tighter and tighter until you look like the old man in the picture. So unless you want to look like that, perform the stretches shown below.
Squats. Using a squat machine will strengthen your quadriceps muscles on the front of your thigh and the hamstring muscles on the back of your thigh, both of which attach to your hip and give it support. The squat machine may be vertical, in which case you’ll start in a standing position and bend your knees until your thighs are parallel to the floor, or it may be on a sliding incline board.
You're more likely to get a hip flexor injury if you've had one in the past, you don't warm up properly before engaging in athletic activity, your muscles are already tight or stiff, or your muscles are weak from being overused. If, while exercising, you try to do too much at once in too short an amount of time, you can also put yourself at risk for a hip flexor injury.
