several years ago my mom had surgery on her lowerback. She is not as active as she once was. She is now 65 years old. She has put on some weight around her middle and wants to take it off. She can’t do sit-up, crunches or any thing that pulls on her back too much right now because the muscles are tight and the spine is stiff, she doesn’t want to take a chance of re-injuring her spine.
She now walks on the tread mill for like 45 min. every other day and is starting to swim some. Are there other things she can do to strengthen her lower back and loose of the the fat around her middle.
Any help will be great.
