Have you tried this exercise?
The simple bridge can be done on the floor or on a bed.
This exercise will activate the muscles in your lower back, glutes (buttocks) and hamstrings (back of thigh).
It will also stretch out your hip flexors (muscles crossing the front of your hips).
As you lift your buttocks up, think about squeezing your them while at the same time relaxing your shoulders and breathing normally.
Perform about 6-8 at a time.
