There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
A Tire flip and a deadlift are very different things the require different techniques, but let's say a gorilla could comprehend technique and could be taught to lift in the same way, you can guarentee that a Gorilla would outlift any human by a large margin. They are built for that type of lift, short legs so the weight doesn't have to move far, long powerful arms that won't give (many injuries in the deadlift are bicep detachments) as well as allowing the gorilla to lower his hips and raise his chest, a giant back, core and glutes which are the primary muscles used during a deadlift and strong traps and shoulders which help at the apex of the lift when you need to keep your shoulders back and your chest out.
When it comes to a Tire flip, it's more about getting your butt low, your feet are crouched beneath then you drive up and forward and most will use their knee at the end for the extra oomph to get the tire over.
I could easily flip our 950lb tire but my deadlift never got over 600lbs, it's the same for any powerlifter, only a handful have ever lifted 1000lbs but you can bet the house that every single one of them has flipped 1000lb tires or more and not just once, they flip it as many times as they can in a cetrain time frame and usually it's quite impressive how many flips they can get in.
