How to: Start feet hip-width apart, with your arms straight out in front of you. Step one foot back on a diagonal, feet flat. Once your foot reaches the floor, lower into a shallow lunge. Keep your knee bent and butt back, twist your pelvis, and rotate your arms back behind your body until they frame the knee. Return to starting position. That's one rep. Do eight reps on each side. Do three to four sets before moving on to the next move, resting for 30 seconds in between each set.
Tight hip flexors can result in lower back pain, hip pain and injury.  A lot of strain is put on those muscles during activities that involve sprinting and kicking.  For example, runners are more prone to hip flexor injuries because of the small, repetitive movement during running.   But even if you’re not an athlete, hip flexor injuries can occur during everyday activities (for instance, slipping and falling or running to catch a bus).  When those tight muscles are suddenly stretched beyond what they are accustomed to, you might also experience pain in the upper groin region, typically where the hip meets the pelvis.   
Downward facing dog can help stretch and strengthen your feet, calves, hamstrings, lower back, shoulders, neck, and hands. Begin on your hands and knees with your shoulders directly above your wrists and your hips directly above your knees. Spread your fingers wide and press your palms into the floor. Now lift your hips and push back with your hands to form an upside down V with your body. Work your heels toward the floor, and let your head hang to relieve any tension you’re holding in your neck. Take 8-10 breaths, and then release.
But there are some pretty serious causes for back and hip pain as well. Lower back pain, in particular, can be a sign of various serious conditions such as advanced kidney infections or a condition called interstitial cystitis, which can cause inflammation of the tissues of the bladder. Sciatica causes lower back pain, pain in the back of the knee, pain in right buttock cheek, unilateral (one-sided) pain, thigh pain, pain behind the knee and calf, and muscle weakness in legs as well.

When I do a deep knee bend like a sumo squat I get a popping in the outside of my left knee. It feels like a big tendon or ligament is slipping per something. It isn’t painful peer se but I’m afraid if I do it a lot it will be. Is that a relatively common symptom for a guy with tight flexors, it bands, etc? Should I just push through it or have it checked out?
It’s a common issue, says Prevention advisor Rob Danoff, director of family and emergency medicine residency programs at Aria Health in Philadelphia. "For people who sit a long time at work, the hip flexors and rotators become tight, and the gluteal muscles become weak," he says. "This combination negatively affects our ability to walk, maintain proper posture, and the stability of our spine."

Ankylosing spondylitis is a type of arthritis that specifically affects the spine. Ankylosing spondylitis causes a severe inflammation of the spinal vertebra that can cause debilitating pain throughout the back region. This condition can cause stiffness and pain not only in the spine but also inflammation, pain and stiffness in the ribs, shoulders, ribcage, hands, and feet as well. Symptoms include a dull pain in the lower back and buttocks, stiffness and lack of mobility in the hips, back, and legs, loss of appetite, fever, and general malaise. Treatment includes physical therapy, medication, hot and cold therapy, and exercises that reinforce good posture practices.
How to: Stand with your feet hip-distance apart. Your feet should be flat, and your legs should be straight. Step your right back behind your body, keeping your hips parallel, and stretch your right hand up overhead at the same time. Step back up to starting position. That's one rep. Repeat eight times on each side. Do three to four sets before moving on to the next move, resting for 30 seconds in between each set.
