He designed the method to help WWI solders get out of bed and back on their feet after being wounded. In other words, it is a type of physical therapy and not ment to be mastered quickly. (I have been doing it for 8 years and still need to be corrected, but it is wonderful and should not be painful)
Any little move, no matter how slight counts! If you are doing the 100 with your feet on the floor, head on the floor but are pumping your arms and pulling your tummy in, That is a good start!!!
You can start with the breathing techniques and just lying on the floor visualizing your belly button sinking in and having your back on the ground.
Baby steps are okay!
Keep trying each week untill you can get your head up, or legs to move.
It may take a while but it's such a benificial form of exercies, it's worth the work.
Lizziness, you are doing great!!!
