Greg Lehman is physiotherapist, chiropractor, a strength & conditioning specialist and an expert in pain science. He recently co-authored a paper titled "Getting out of neutral: the risks and rewards of lumbar spine flexion during lifting exercises". The paper synthesises some very interesting research on the topic and we discuss its implications for coaches and lifters.
