I teach yoga to persons with disabilities where the person often has a weaker side which sometimes cannot move without assistance. In class I often encourage them to do the pose or movement on the stronger/ dominant side first to really feel in their body how the movement feels. I then encourage them to close their eyes and visualize the second side doing the same movement. They will often find an increase in strength and flexibility on the weaker side. There have been studies done on the powerful effects of visualization even for athletes. Check out this link.

One morning right before I awoke, I had a dream I was in Crane (Bakasana) Pose. In my dream, I could feel my abdominal muscles engaging and all the muscles working that needed to work. During my morning practice, I told my husband my dream and that I was going to see if I could do the pose, which I could not do before. Wow, I got into the pose with ease. I shared my experience with my students and encourage them to keep visualizing!
What is something you want for your life? Try some visualization. I would love to hear how it works for you!
