Australian researchers randomly assigned 44 people to a Pilates program and 43 people to a general exercise regimen for six weeks. All ranged in age from 18 to 70 and had experienced chronic lower back pain for at least three months. Overall the study participants were slightly overweight, had a long history of back pain and about a third were taking medication for their condition.

Both exercise programs were held twice a week for an hour, and lasted six weeks.
