Since I can remember, I have always had trouble doing sit-ups as I find that although I can feel it in my stomach I also get ache in my lower back and neck which suggests im straining. I have tried so ahrd not to but I jsut cant to them lieing flat on the floor, so I tried crunches and its the same in my neck so I have to use the sit-up amchine But I have been told free sit-ups are best...any advice for me here?
Thanks!
Thanks!
