I've always been fascinated as to how humans stack up against alien species, physically, so I am starting this thread. If you have anything to add, or corrections to make, feel free 
It seems to me that physical strength levels vary in the Trek universe, but I have always been curious how humans stack up against other Trek species.
First, it is hard to define the average strength level of a human. For simplicity, let's just accept the following as the "average man."
The Average Man:
height = 5'8 - 5'10
weight = 160 - 180 lbs.
bench press (max) = 135 - 185 lbs.
deadlift (max) = 185 - 235 lbs.
squat (max) = 185 - 235 lbs.
bicep curl (max double) = 60 - 100 lbs.
bicep curl (max single) = 30 - 50 lbs.
...and just accept for sake and simplicity of argument, the "average" woman is roughly somewhere between half to 2/3s that.
Relative to the average human, it's been stated:
Human augments: Khan says to Kirk in Space Seed, "I have 5 times your strength."
Vulcans: Their strength level varies, but I believe it is stated in DS9, "Take Me Out To The Holo Suite," Vulcans are 5 times as strong as humans. Other sources seem to indicate 3 times as strong.
*Correction: Vulcans are 3 times that of humans, according to DS9's "TMOTTHS"
Romulans: This is a weird one. They never demonstrated superior strength in any series, and even seemed equal to humans, DESPITE their Vulcan lineage. However, Star Trek 2009, Nero picks Kirk up like a rag doll, with one hand. It is reasonable to assume they are as strong as Vulcans, I think, so they must be 3 times as strong as a human.
Klingons: While Klingons can be agreed to be tougher than humans (redundant vital organs, train as warriors from childhood and assumed to focus on physical fitness and fighting), on average they seem to be about as strong as humans. Worf would be an exceptionally strong Klingon or human, so I am not sure he would be a good example as the average "Klingon," and there is Star Trek 3, where Kruge picks up Kirk and throws him easily, indicating superior strength. However, young Spock threw a Klingon about as far, himself. So, I think Klingon must be somewhere between a human and a Vulcan, at maybe 1-3 times the strength of a human.
*Correction: Average Klingons are probably not as strong as Vulcans, so they are likely 1-2 times as strong as humans.
Jem Hadar: They seemed on par with Klingons
Ferengi: They seemed the weakest, at probably half that of a human, except in their debut, The Last Outpost. In that, Data said they were "stronger than they appear," and seemed as strong as a human.
Andorians: When Shran and Archer dueled in United, Shran displayed no superhuman strength. However, in Cease Fire, Tarah, the female Andorian,seemed to be stronger than Archer. Also, in United, Talas took out a Maco pretty easily. This could mean Andorian women are stronger than Andorian men.
Data\Lore\B4: I think several times, Data says to various humans he has "many times" a human's strength. I don't know why, but for some reason I have stuck in my mind that Data is 10 times as strong as a human.
ODO\Founders: Not stated, but has to be at least equal to Data.
Borg: Data overpowered a Borg (assumed to be human) with one arm easily in Descent, but probably depends on the race of the Borg prior to assimilation. Maybe human Borg is as strong as an average Vulcan?
