Stretching: Side Splits

[fiXXXerMetallic]

Any help?

I have been working on these for a while - I have the front split almost down, but I just can't get my legs to open to the side anymore.

I read Thomas Kurz's Stretching Scientifically and I followed it pretty well. One thing that he mentioned is that low hip adductor strength can stop someone from accomplishing the side split. So, I started working on it, and after a few months, I am now able to hip adduct the entire machine, which is 190 pounds.

Any ideas? Please - I want to do a side split so bad!

Are you already doing isometrics?

No, I don't think so.
I lost my Stretching Scientifically book a few months back, so I'll have to do some reading.
