A scientific experiment from the 1920s found that chimps are 4 times as strong as humans. two chimps, a male and female, who had been raised in captivity were asked to single- and double-hand pull a rope attached to a dynamometer. The female did a double-hand pull of a little over 1200 lbs. The male did a single-handed pull of nearly 850 lbs. Several College Football players were asked to do the same. The strongest of the bunch could only single- and double-hand pull just over 200 and 400 lbs, respectively. I would imagine that wild chimps could have pulled even more!
In his book Next of Kin: My Conversations with Chimpanzees (1997), Prof. Roger Fouts mentions that one of his sign language-capable chimps climbed a tree and would not come down. He tried to use the leash attached to the chimp to muscle him down, but he writes:
"That was my big mistake. Booee [the chimp] reached down, grabbed the lead with one arm, and lifted me clear off the ground--like a weight lifter curling 180 pounds with no discernible effort. I experienced a long moment of complete terror as I swung helplessly in the wind."
any force, it matters how much the weight is ...
The input force is how much force you use to pull on it. The output is what is lifted.
A push or a pull is a force
Poo is subject to the force of gravity, 9.8 m/s2.
A force can be either a push or a pull.
Force can be both a push or a pull

The upward support force is as much as the downward pull of gravity.
The upward support force is as much as the downward pull of gravity.

A push or pull that acts on an object is a force.
