Hello,
I have been practicing Bikram yoga for over 2 years now and still have tight hips. Based on Gabrielle’s great suggestion I tried the hip stretching poses. It helps! Here’s my sequence. After doing an hour practice and 2 min. of savasana, I do thread the needle pose on both sides, lay down in savasana, do another 2 sides of thread the needle, lay in savasana, Do a modified Pigeon on both sides, savasana, another set of modified Pidgeon, savasana, sit up, Bound Angle pose, a modified staff pose to release the inner thigh muscle (ie. legs out straight in front of body on floor, but with relaxed feet & legs), Square pose with one foot on top, modified staff pose, square pose with opposite foot on top, final savasana. I modify based on the amount of stiffness and pain. I found all poses at yogajournal website.
Thanks again Gabrielle for the great suggestions! Helen
