Very difficult for a person to reach muscle failure. We have too many motor neurons. To recruit enough motor units to lift a given weight, we have to activate too many neurons. A chimp is twice as strong as a human lb per lb because with a chimp, a single motor neuron recruits more motor units. But humans have adapted all these extra motor neurons to achieve fine motor skills like threading a needle or playing a violin and for accuracy like throwing a spear or a football to hit a target far away.
A chimp can't do those things because one signal and the muscle reacts with a large portion of its entire strength. A human would have to generate far more electrical signals to activate an equal number of motor units.
If a human were to recruit all their motor units, like has happened under extreme circumstances, tendons would be ripped from the bone. Like the hiker that got pinned under a 2,000lb rock and pushed it off himself to escape death. Everything was torn but it was more weight than the bench press record at the time. And even then there is nothing to say he couldn't have done it again. And the 16-yr-old Ohio kid who lifted a 3,000lb car off a guy and couldn't explain how he did it.
That someone could get close to firing all type I and II fibers in a single set or a rep in a specific muscle or group in a gym under non-threatening circumstances is not realistic to me. I don't care what they say. And if they did, it would be devastating to their health.
When you see a Nat Geo video of the snow leopard chasing the snowshoe hare and the hare just barely escapes, people feel good for the hare. But that hare will likely die soon later anyway because the exertion was so intense that even the hare's central nervous system is in shock and the immune system collapses, everything collapses.
The closest I ever got was doing crevasse rescue training in Washington state where outr #3 guy was 200+ lbs and the sun was high and ice had melted just enough where the slings just didn't have enough friction to hold and I couldn't get him out. The water was rising and he needed out of there. I had to pull him out. A few inches, tie off, a few inches, tie off. Finally got him out and I slept the rest of that day and all night through. I was demolished.
