Abdominal Crunches - better with anchored or free feet? - free abdominal pain more condition_symptoms

Hi, I recently started so that some abdominal exercises, because I want a better vector section. However, if I remember-ups (standard, no bicycle or cracks) of the cross, it is difficult to monitor the movement of walking, so that my feet are not anchored - It is difficult to balance, without lifting the legs on the ground when I stop, and somehow the feeling that I was rocking back and forth in my example, # # buttock muscle bones, visibly uncomfortable. But apparently, if your feet and legs, and then automatically to a lot of tension, and we have also flexed their effects on the stomach.
Can someone with experience tells me that you were going to choose who they think you should?
Thank you very much
