This second one can also be modified to give an excellent stretch to the QL muscles.
Considering how many people come to me with tight hip flexors, I would say that close to 75% of people should be doing these stretches often. Very often. Anyone who has a job where they sit for most of the day should absolutely be stretching their hip flexors, and these basic, unassisted stretches are a great place to start.
I think I’ll go do some, now, in fact. Maybe you should give it a shot, too. It should only take about 4-5 minutes.
Alright, I’m back. It only took 4 minutes.
If you work at a desk for long hours, I recommend doing these as often as you can. Of course, not everyone has an office with space, but even spending 5-10 minutes in the morning and evening is better than nothing.
Now that we’ve hit on some basic stretches, we’ll also want to work on building up the complementary postural muscles. In this case, we’ll want to work on the glutes.
Often (though not always), tight/tense hip flexors correspond with comparatively weak or misfiring glutes. To get those muscles revved and activated, I recommend some isolated contractions. Following our hip flexor and quad stretches, I suggest some two-legged and one-legged glute bridges and elevated glute bridges.
Glute bridges are pretty simple. You lie down and plant your feet flat on the floor, knees bent. Bingo! You’re already in the starting position. Depending on your leg length, unique muscular imbalances/weaknesses, etc… you may need to or want to modify the exercise, but the standard version is pretty good all-around so don’t stress out too much over perfection.
Now, with your feet flat and knees bent—engage your glutes, press through your heels, and push your pelvis toward the ceiling. You should feel the contraction primarily in your glutes, though your hamstrings and lower back may fire as well. At the top of the motion, squeeze the glutes and feel the muscles activate. You may also feel a stretch in the hip flexors, at this point. Take a pause, lower yourself back down, and repeat.
Here’s a stock image to give you a basic idea:
