Lower Back and Obliques

I use a combination of Ab exercises to work Upper and Lower Abs, Obliques and the Abdominis. Traditional crunches work well for upper abs. I use the seated ab crunch for the lower abs. For this you sit on the end of a bench, lean back and balance yourself with your hands, extend your legs straight out and then pull them back toward you. I use side bends with weights and the Two Handed Wood Chop for obliques and Bridges for the Abdominis. For the back I use traditional back extensions.
