What also is a "curve ball" in developing a personal exercise/movement routine=what are the end goals. Cross training for running, shoulder development for looks, bounding height for dunking, flexibility for mixed martial arts, power for contact sports.....this is where it is so important to get a "second opinion" on applying an exerciser routine to your life. I don't mean with a sportsmedicine doc, I highly value to ingenuity of exercise physiologists in figuring risks, strengths to embrace, weaknesses to address and lifestyles that would limit a long term sustainable life change. So this is where my tight hip/50+ year old yoga student has entered into the "melee" of personal fitness programs. For the short 8 weeks of having him come for guidance, I can at least help him in planning a continued exercise/overload program. If we can use 3 easy poses of yoga as a staple or preexercise warm up, over time he should be able to gain progressive lengthening to a very contracted hip capsule. Keep up with the basics no matter how deep he gets into other sports/activities and one day he'll have the flexibility of a highschool gymnast.
Problem with hips is most americans view the groin and hips as very private. The figurative concept of hiding from sight always translates to physiologic function. Although a painful image, think of a sexually abused kid dreading the gyne office PAP smear when she gets into her 30's. The psychology of injury always limits the form and function. One of the reasons I save hip poses for the end of class is for the first 45 minutes, I not only get students to warm up body temperature but they also have worked on breath and relaxation so any psychological worries are not as distracting compared to before class. If all distractions (I mean psychological ones like "my hip is about to break" or "feels like the muscle is going to tear" or "shoulder is about to come out!") are calmly removed from the forefront of one's attention, it will usually be able to apply exercise/overload. Getting to the point where the hip is tight in the movement but not terribly painful....then holding at that point, concentrating on breath, and when guided-slowing coming out of the pose with control. When I was captain for my school Track and Field team, I would lead warm up and remember bouncing the joint in the 1980's to provide warm up, flexibility, and stretching-usually on cold ground!. (How wrong I was!!!) The slow entrance into range of motion, gradual addition of torque and length, and relaxed breath will usually convince the muscle group to release it's contracted state after minutes. Some will note after a long hold the sudden realization that the knee is now touching the floor in pigeon pose or the forehead is on the knees in forward fold. (Others it takes a few months)
Here is a video link to a few poses that I showed my student and helped him to adapt (via use of yoga blocks and blankets) for daily repetition/ritual.
Of note is it took me 2 years to attain pigeon pose equal on both right and left. I suffered a hamstring tear going around the back stretch 110yards in a 440yard medley for state championship and coach said he heard a pop from across the field. Cost the team 1st place and always held that in the back of my mind (and the back of my hip)...and that was 1979!
