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.
A basic bodyweight glute bridge is one of Lefkowith's favorites. Want to try it? Lie on the ground with your knees bent and your feet flat on the floor, and push your hips up toward the sky, squeezing your glutes at the top. This will not only help get your glutes in the game, but it also gives your hip flexors a chance to stretch out. (Try these five hip openers, too.)
Your hips are just one of the areas of your body that are prone to tightness and injury if you are a runner. Every stride that you make requires your hip joint to pull forward, and every time that you plant your foot on the pavement, your hips feel the impact. Performing hip stretches before and after a run can help you avoid injury and keep your hips loose and limber. Ease into your hip stretches and do not bounce. Try to hold each one for 30 to 40 seconds and stop if you feel any discomfort.
Since someone has to do the job… (Side note: That’s one of the coolest things about our body. There is always a backup system. Always another set of muscles ready to take over. Even if they are not the most effective and it leads to pain and tightness.) So, who takes over for spinal stability when the abdominals aren’t fully working? The psoas of course.
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.
