It seems to only help the large muscles that get the workout. So running and walking do NOTHING for your back but help your arms and legs.

But I've found one exercise that does help the back!

This guy does it: http://image.tradevv.com/2010/11/22/frefitness_1690634_600/fitness-machine-45-degree-back-extension-k09.jpg

Back extension machine. You hold a weight against your chest (depending on how much you need) and go from your upper body hanging down to it being arched.

But hand weights limit the range that you have resistance--I recommend hugging a weight against your chest, instead. For me at least, my default hypertrophy means I need a good 20lbs to make this work my muscles hard enough to make them LET GO.

Unfortunately, this is impossible in pregnancy!

There are a couple of other back extension machines that have weight systems. They work, too. But I've seen this most often in the gym. It takes about 3 days to start making a real difference--and then it really, really does!
