Sitting should not have to cause low back pain, and there are things you can do to remedy this annoying problem.

Why do some people have low back pain after sitting for a while? Let’s assume that if your low back hurts after prolonged sitting, it’s not because you recently fell, were in a car or ski accident, or wrenched muscles while lifting something heavy.

“Sitting creates the most pressure on the intervertebral discs,” says Dr. Moshe Lewis, MD, Chief of Physical Medicine and Rehabilitation at California Pacific MedicalCenter – St. Luke’s Campus in the Department of Orthopedics.

“Solutions include inversion/tilt tables, traction and core strengthening,” says Dr. Lewis. Inversion/tilt tables and traction are not practical for many people, but anyone can get started on core strengthening.

I’m a personal trainer and recommend core strengthening exercises several times a week.

The core is the low back and abdominal regions. There are many core strengthening exercises out there.

A few examples are the back extension with leg support (just about every gym has the equipment for this), and the “good morning” exercise.

Another exercise that will engage the core is single-leg chair squats. Sit on a stable, sturdy seat. Lift one foot off the floor and rise with only the other leg, into an erect posture.

Lower back into the seat with control; do not drop or plop back down. If this is impossible, use a higher height seat. Do each leg 8-12 times. Believe it or not, this will do a very good job of recruiting low back muscles. Do two sets each leg.

WARNING: At no time does the support foot leave contact with the floor! As you sit back down, the foot of the rising leg STAYS FLAT on the floor. Lifting it off is cheating! It stays PUT.

A person with a strong, conditioned core will not experience low back pain after long periods of sitting.
