You'll need a resistance band for this one. With this exercise you're focusing on four movements—flexion, extension, abduction and adduction. Try and stand up straight while doing the exercise. If you have to lean excessively, step closer to the anchor point of your band to decrease resistance. You'll find that not only are you working the muscles of the leg that's moving, the muscles of your stance leg will work quite hard stabilizing and balancing.
Tight hip flexors can also make it harder for your glutes to activate—since they're opposing muscle groups, when one is really tight the other becomes lengthened. When a muscle is more lengthened than it should be, it takes away some of its ability to contract. When your glutes are in this compromised position, it can cause other muscles to do more work than they should, making your workouts less efficient and sometimes, increasing your risk of injury.

The sacroiliac joint connects the lower spine to the pelvis and any injury or strain to this area can cause a lot of back, hip, groin, and sciatic pain. Sacroiliac joint dysfunction (SJD) can cause not only radiating lower back pain but can also severe pain in the hip area including hip pain at night when sleeping and hip pain when sitting. Often the pain resembles that of a hip injury it is so severe. SJD can also cause severe pain in the groin area. Women may also notice pain running along the distribution of the sciatic nerve. Treatment for sacroiliac joint dysfunction includes rest, anti-inflammatory drugs, and sciatic nerve massage.
You can strain or tear one or more of your hip flexors when you make sudden movements such as changing directions while running or kicking. Sports and athletic activities where this is likely to occur include running, football, soccer, martial arts, dancing, and hockey. In everyday life, you can strain a hip flexor when you slip and fall, for example.
