Ive got a big problem. My lower back is far too strong, so it tips(right word?) my hips and I got a hollow-back, often with pain when I have to stand for a long time.
I need to strengthen my abdominals, but if I do crunches and situps my lower back will hurt after a few reps, so I think it does some of the work...
Is there a chance to isolate the abdominals, maybe an excercise where I can add extra weight?
Hope you can help me
