Does anyone have any tips for learning to do the cartwheel?

1. Ask on 'that-other-forum-that-deals-specifically-with-this-art-but-shall-remain-nameless-here-out-of-a-sense-of-decorum-and-proper-respect-for-this-current-forum'.

2. Take the cartwheel out altogether. In preparation for my BB test, I started taking private lessons with Master Lee in Abingdon, MD (about 2 1/2 hrs drive from my home dojang), with the approval, blessing, and encourgament of my Instructor. The first time Master Lee saw me do SSGB #9, he told me, "I do not want you to do a cartwheel there." I think it might be optional for the 'over 40' crowd (and probably not recommended for the 'well-over-40' crowd).

3. For whatever meager success I was able to muster in the cartwheel, I actually started practicing it 6 months before I got to SSGB #9. I found it easier to practice with something in my right hand - I recommend starting with a short stick.

I recommend starting with a short stick.
Amen.

There aren't very many people who can do the cartwheel well, but unless you are instructed otherwise, be ready to do it. I know I can't do it terribly well, but I can muster it.

Remember, you aren't so much throwing yourself as you are falling with some angular momentum. This means that you're going to end up fighting yourself during the cartwheels, so the first step is... relax! The more you think about what you're doing, the more you seize up.

Second - Remember to keep your legs vertical. Chances are, you're bending them too early during the flip, and you fall off balance, either forwards or back.

Also, I wouldn't practice it too much in one sitting. Do it a couple times, every day, then move on. Frustrating yourself with it is not very conducive to learning it.
