I have been working on my stretching and have even attended a few yoga classes to help with my hip flexor flexibility. I feel I have been getting better but wanted to help move everything along.
I am also considering buying some equipment to help with it too. One of then pieces I am ordering is the leg stretching machine: http://www.bestlegstretchers.com/shop-gear/pro-swift-stretcher/
They also have a video that shows other stretching equipment they carry but I think the pro stretcher is what I want. http://www.youtube.com/watch?v=UFSSeYvVwqc
