Steak vs. Jerky
One thing I've noticed is the longer I do this, the softer my muscles are starting to get. When I first started, all of my muscles were hard, and tender to the touch. They kind of felt like jerky, hard and unpliable. In fact, I hated being touched because it hurt. I hated shaking hands, being hugged, and all that stuff.
Now, it's easy for me to tell what areas I need to work on just by touching the muscles. The areas that are getting healthy are soft and pliable, kind of like a nice steak before you cook it, and they don't hurt. The unhealthy muscles feel more like jerky, hard and unpliable, and painful to the touch. I've been doing a lot of self-massage, and trigger point work on these areas and it's helping soften those tissues up.
When I was young I did a lot of weight lifting, and I thought it was good when a muscle was hard, but now I realize you don't want that. A healthy, pain free, muscle should be soft and pliable. You want muscles that feel like steak, not jerky.
