Find a good yoga studio that teaches restorative yoga
in your area, or look into Yin Yoga
or Svaroopa yoga
- both these forms of yoga are very therapeutic - and especially, they help open up the hips/tailbone/pelvis - especially the psoas and iliacus muscles. The psoas is your tenderloin, essentially. It connects at the top of the femur, runs through the pelvis, and re-attaches all along the lumbar spine.
