I think it would be if you have a good instructor who gives you good cues to make modifications. Unfortunately, I went post-partum and hurt my back after one class. you have to be very careful that your back is supported.

If you are out of shape, I would recommend getting more in shape first and if you are interested, doing somethig like Pilates to strengthen your core to help prevent injury.

Can you go to The Bar Method if you're a newbie to working out and are very out of shape? Would it be safe?
