Lions are known as the kings of the Jungle but I feel the incredible hulks of the Jungle are of the Gorilla. Gorillas have strength that surpasses more then 10x of the strongest men. Yes they're structure is different when it comes to walking but yet with chimps they're the closest to us humans, they have hands, they have feet and have torsos that resemble a human. They walk different because they're arms are longer then their legs and need to adapt to walking on their hands.
I personally feel that if we were to get strong then we need to reverse evolution from our modern methods of today. Today in most fitness circles we can't compare to the old school ways of training and that's most likely a good thing. Today we have people who are more overweight then any other time in world history, we have gyms that have just lost its roots to whats really important and looking good and being overly cautious has taken over. Very few of those that know the real secrets to strength & health look to what the animals and early men have done to become strong. Animals don't lift weights and try showing off their muscles, they use their strength to survive and early men strived to survive harsh weather conditions and move boulders to help shield themselves and swam to catch fish, run as hard as they can to get away from predators and used spears to kill their food of some of the wildest beasts of the time.
Getting strong using weights has its own benefits but modern trainers make it look like a joke and those old-timers from the golden ages of strength would be rolling in their graves. If you're going to use weights, do the simplest one's and stick with that, Presses, Pulls, Abs, Grip Work and basic leg training is all you'll ever need. Isolating muscles is only good for one thing and that's rehab other then that it's useless. When it comes to weights, the simpler, the better...Dumbbells, Barbells, Kettlebells and a few odd objects here and there is all you'll ever need.
When you learn to become strong, its best to look at not only the muscles of the strongest animals or the strongest of humans but take a good look of how strong the tendons are. I'd say the best animals with the strongest tendons are Gorillas and Wild Cats because they have to reach, climb, crush and pounce while defending against predators and/or fighting for food. It's better to pull a muscle than tear a tendon. Huge difference between the 2. Pulling a muscle recovers quicker, tearing a tendon however can put you out of commission a lot longer because the tendons are the things that help keep the skeletal structure together while the muscles are the tissues that cover the skeletal structure. Tendon strength creates a chain reaction of how strong you really are. Take a bodybuilder for example in this day and age. He's more into building muscle so he can look as big and powerful as possible but does little to no training in the tendons and chances are he's going to get injured quicker then any other athlete including fighters and major sporting athletes.
Developing Ape strength without weights is very simple an doesn't take that much time to learn or do. Look at the basic things they do, climb, walk, pull, push and move in awkward positions. Learning basic elements in their evolution can help you become 3x stronger then the average human. This of course means you won't build the strength that they do because its the way their structured and their nature is used but that doesn't mean we can't adapt. Some of things they do might seem silly but if you're open minded and look at another prespective you might realize that you can become stronger using those so called "silly" stuff.
The only time you'll ever see an Ape lifting weights is if researchers experiment to find out how strong they are in that area and if you see some knucklehead meatball of a bodybuilder trying to lift some weird looking weight. Apes carry strength that makes most weightlifters look like chumps and who's to say we can't try to imitate and build superior strength ourselves. We can really learn the true secrets of creating Animalistic Strength with the simple points of observation, experimenting and adapting. In the world of fitness it's not a bad thing to turn reverse evolution and become the strongest person we can be.
