After a month without practicing my skills, I have lost the ability to do a hand roll on my left side.
However, I discovered something interesting when I went to practice yesterday. I managed to do a one hand roll very slowly.
I ended up in a semi balance brace position, which I feel is essential for doing the strait jacket roll. I'll be testing it out farther the next time I go down to practice and hopefully discover the secret of the strait jacket roll soon.
However, I still need to work on the flexibility of my left side. When I lean out into a balance brace position on my right side, the coaming is pressing below my pelvic bone, around the hip. But on the left side the coaming is pressing at my waist.
