Why an exercise ball, though? "Using an exercise ball is a great tool to help with back pain," Dr. Dale O’Leary, a board-certified orthopedic clinical specialist at Spectrum Health Outpatient Rehabilitation, tells Yahoo Life. "It can help with strengthening and stability."

An exercise ball can build up your core muscles, which are crucial to help manage back issues, Dr. Medhat Mikhael, a pain management specialist and medical director of the non-operative program at the Spine Health Center at MemorialCare Orange Coast Medical Center in Fountain Valley, Calif., tells Yahoo Life. "Your spine is a column that is supported by ligaments, but it also has a lot of muscles supporting it, including your core muscles," he explains. "When your core muscles are weak, there's a lot of tension and load on the spinal column — and that can lead to pain."

But when you have a strong core, it helps support your spinal column and lowers your risk of back pain and tightness, Dr. Mikhael says. "An exercise ball can be a great way to strengthen core muscles," Dr. Mara Vucich, a physiatrist at the Maryland Spine Center at Mercy, tells Yahoo Life.

Experts say there are a few ways y you can use an exercise ball to reap the back-pain-fighting benefits:

Do bridges. O'Leary recommends this move: Lay down on the ground, belly up, with your feet on the ball. Lift your butt off the ground into a bridge while keeping your belly button drawn in. Squeeze your butt muscles in the process.
Planks. Holding yourself in a plank position with your bent elbows resting on the ball and your toes on the ground, can be a good way to build up your core, Mikhael says.
Do seated kicks. Sit up tall on the ball with your knees at 90 degrees. Pull your belly button in, and kick out one leg at a time. This works on your posture and stability, O'Leary says.
Sit on the ball. Work at a desk? Vucich says you can sit on your ball while you type. "You have to stabilize your core muscles to balance on the ball," she points out.
