One of the things that you can use EFT for is peak performance. And there are all kinds of aspects to peak performances, but one of them is increasing your range of motion. So for now, let's pick a stretch that you are working on. Remember to be gentle on yourself. But try something that you know you have limited range of motion. So maybe try touching your toes or do a shoulder stretch; something that you are familiar with.
So first try the stretch, now rate it. A "zero" is you had a perfect, perfect stretch and you have complete range of motion. And a "ten" is you can barely move. Now that you have your rating, let's get started.
Start at your karate chop point, even though I have this limited range of motion, I deeply and completely love and accept myself. Even though I can't move as much as I want to move, I choose to move freely. Even though I have this protective memory which is keeping me from moving freely, I deeply and profoundly love and accept myself anyway. Start at the eyebrow point, this limited range of motion. Side of eye, this stiffness in my body. Under eye, limited range of motion. Under your nose, protective memory in my tissues. Chin, protective memory in my cells. Collar bone, I want to move freely. Under arm, I choose to move freely. Liver point, I will relax into moving freely. Wrist, my cells are open to moving freely. Top of head, this limited range of motion. Now, breathe in. Now try to do the same stretch again. Now do the same stretch again and adjust the rating to what it is right now. And you can continue on to increase, to further increase your range of motion with each round.
