You mean the adductor flyes? Adductor flyes are an exercise Tom Kurz thought up to increase the strength of the adductor muscles. Just attach weight to your shoes/feet with ankle weights or weighted boots, lay on your back, spread legs directly above hips, close, spread, repeat. Control and steady tempo are essential. Tom Kurz's website address is: http://stadion.com/ He has quite a few products and all of them are excellent. If you're interested in purchasing one of them, let me know and I can give you some extra info. I own quite a few of them.
