Hi!
Here I’m demonstrating a great way to fully target all of the muscle fibers of the hip flexor muscle group. Since some of the muscle fibers attach to the spine, I’m laterally flexing to the opposite side.
If you don’t have a ball, simply lean your hand on your knee. Be sure to lean forward of the right knee seen here. Plus you can pulse gently. Hold about 20-30 seconds.
The hip flexors can get tight with athletics especially running and cycling. They can also tighten up and shorten if you sit a lot. The danger is that when this happens, it can affect the mechanics of your lower back and manifest in pain and discomfort. I hope this is helpful!
Enjoy your day!
