So I just finished my stretches from 9:3 and I feel a difference already. From the intro sessions into the first session, I felt strain in both knees around the sockets, especially on the right. Probably from sitting at my desk for long periods of time without really moving (guilty as charged). Today, there is a difference. Not as strained and I think the tendons of whatever those things are called around my knees are beginning to elongate in the stretches more. Also, my hips are more supple and pliable after each workout. I feel no tightness which I have felt a lot where I have to constantly stretch to the sides. After one workout my hips thank me. Also my posture is getting better. I noticed I sit up straighter. I love this!
