Does anyone have a diagram, pics, video, very good description, etc.. of how to do completely proper crunches or situps.. or any ab exercises?
Very often when I get heavily into working my abs.. I end up with real sore back issues.. Obviously, I must be doing something wrong.
Anyone help? Thanks.
Didnt know if this fit into body building.. and didnt think anything to do with weight lifting either. So I put it in here.
