With the recent spate of superhero movies, it is easy to forget that not every movie has a superhero in it. Even the superhero films aren’t always about someone on steroids (Captain America) or weather presenters (Thor) but are instead about your everyday billionaire playboy (Batman, Ironman, Arrow). So it is easy to forget that feats of superhuman strength are not meant to be the norm in films.
Think about the scenes where the everyday hero is clutching the edge of a building by his fingertips whilst the love interest or bad guy is dangling from their other hand. Of course, the hero never loses his grip on the ledge, but the bad guy may slip from his grasp.
We accept that scene as plausible because we have been brainwashed into thinking that the average person can hold their own bodyweight with a single hand for extended periods. Double their bodyweight? They can hold that for the length of a dramatic moment – a period of time that is impossible to measure in real time since dramatic speeches and slow motion really mess with reality.
The problem is that outside of gymnasts, rock climbers, or people who crush rocks with their bare hands for a living, the Average Joe wouldn’t even be able to hold their own weight for more than a few seconds, especially not if they caught themselves from a fall. Elite grip strength can be measured a few ways, but the Captains of Crush grippers are one easy way to distinguish strong hands. The #1 requires 64kg (140lbs) of force to close, while the #3 gripper takes 127kg (280lbs) and is regarded as world class grip strength. Just for shits and giggles, they made a #4 gripper that requires 166kg (365lb) of force to close and has been officially closed by 5 people. Ever.
Watch this world-class rock climber hold just over double his bodyweight with two hands, not one hand, for time as another example:
So let’s just assume that our generic action movie conforms to long-held stereotypes of protagonists. This movie stars an everyday hero who weighs a buff 80kg and his falling love interest is a lithe 55kg, and they totally get naked in the second act for purely artistic reasons. That’s 135kg hanging from the hero’s fingertips, a weight that even a really strong person wouldn’t have the grip strength to support. Two normal sized adults are not going to be hanging onto that ledge for any length of time.
Which brings us to the next amazing feat of strength in this scenario: lifting that falling love interest back to safety. For a strong person, the 55kg gravity lover isn’t exactly heavy. A buff 80kg hero could probably clean and jerk a dumbbell weighing that much…. assuming they work out, have some chalk on their hands, were able to get some leg drive happening, had decent technique, and that the dumbbell wasn’t particularly unwieldy. But most falling love interests are a tad unwieldy, not designed for easy lifting – no obvious knurled handles – and there isn’t a lot of leg drive happening when you’re dangling from the side of a building by your fingertips. Yet without fail, the hero manages to get them both to safety. Well, unless it is one of those tragic character defining moments, in which case the hero will be in the same situation later and will find the determination to succeed the second time. Sucks to be the first love interest in that scenario.
Interesting to think about just how many amazing feats of strength are passed off as normal in movies.
