I have trained aikido for 6-7 years.  I haven’t been doing BJJ long enough to know if it has really helped me at all.

There are some similar techniques, though.

In Aikido, we do hip throws similar to the judo throws in BJJ.  We do shoulder compromising locks (shihonage), and basically standing americanas.  We also do standing kimuras.

Many Aikido techniques end with uke submitting — so, one thing’s for sure — I definitely already know how to tap! : )

In any case, this dvd looks amazing.
