Editing Smith machine (section)

==Use as a self-spotting device==
Behind each vertical post (runner) is a series of slots on which the barbell can be hooked. This means that unlike an ordinary barbell, the Smith machine need not be re-racked after a set of [[Strength training#Terminology|repetitions]]: it can be secured at any point. This is intended to make it safer for those who lift without a [[spotting (weight training)|spotter]], as one only needs to twist the wrist in order to lock the barbell in place in the event that the weight becomes too great. Most models also incorporate blocks, pegs, or other devices which can be adjusted to automatically stop the barbell at a predetermined minimum height.<ref name=clubindustry />

This does not fully eliminate the inherent danger in having a heavy weight on one's back, however, and may instill a false sense of confidence.  In 2001, a Smith machine user became [[quadriplegic]] when the apparatus crushed his spine.<ref name=clubindustry>{{cite web|url=https://www.clubindustry.com/mag/smith-machine-lawsuit-ends-144-million-decision|title=Smith Machine Lawsuit Ends with $14.4 Million Decision|date=September 1, 2003|publisher=Club Industry|accessdate=March 16, 2019}}</ref> [[Bench press]]ing while alone is dangerous in general, but even more so in a Smith machine; if one gets trapped under the bar, it cannot be rolled or tipped sideways off one's chest or neck, which has led to at least one fatality.<ref>{{Cite web|url=https://www.couriermail.com.au/news/queensland/bray-park-teen-ben-shaw-donates-organs-after-fatal-weightlifting-accident/news-story/2d3ca08121be796b1bd1383e64d38436|title=Ben's generous last gift of life|date=October 1, 2017|website=www.couriermail.com.au}}</ref>
