There are number of articles saying some hip flexors inflexibility cause stress on spine and hence cause pain in lower back due to crunches or leg lift or even squats. What can i do as exercise which will prevent my back from injury due to performance of these exercise? please suggest safe exercise which wont need an expert to do correctly.
As i understand hip flexor and extensor weakness is responsible for Psoas major activation, but to strengthen flexor extensor more pressure will come on Psoas. It is becoming a catch39 situation.
