Low back pain aggravated by weight machines

The use of weight training machines and doing stretching exercises to increase flexibility are both likely to aggravate low back pain, a large study shows.

This has prompted Sports Medicine Australia to advise people to ditch the machines for free weights and to go easy on stretching activities.

Their study, published in The Journal of Science and Medicine in Sport, uses longitudinal data from 4,610 adults who were followed over five years.
