I thought it was impossible for me to get into double lotus me being 5'6 with the shortest tree trunk legs ever. I have always been flexible, can do splits ect, but could never achieve double lotus. I simply gave up thinking my legs are too short and muscular or what ever. After watching some mastering the system it inspired me to give it another go so for the past month i have been trying every night for hours while watching mts. Even with a broken foot hurting like a mofo I finally got it tonight while watching the new episode. So If anybody was in my situation dont give up it is possible, just be persistent, do lots of knee stretches, and definitely dont make excuses like i did.
