Did you know that Sloths are the undisputed pull-up world champions?
From the moment they are born sloths are able to lift their entire body weight upwards with just one arm. Not only that, but sloths have 30% less muscle mass than similar-sized mammals and are over three times stronger than the average human.
They have a highly specialised muscle arrangement that can produce enough strength to withstand the force of a jaguar trying to rip them from the tree.
Specialised tendons and muscles comprising of ‘slow twitch’ fibres enable the sloth’s hands and feet to lock into place. This enables sloths to hang upside down for long periods of time without wasting any energy.
This unique locking mechanism is also how sloths are able to sleep while hanging from a tree branch, and they have even been known to remain suspended upside down after death! Poor sloths!
