Physically Achilles was about twice as strong as Matt Murdock Pound for Pound, and he weighed more with all that muscle mass.
Achilles was pretty close to a cro-magnum man, obviously he built muscle faster than any modern man could, and he had achieved maximum muscle mass for his body type - which was an extreme mesomorph with highly aggregated muscle fibers (spear throw).
Kingpin had achieved maximum muscle mass for an extreme endomorph who was about twice the size of Achilles, and Boagrious was an endo-mesomorph who was three times the size of Achilles (It's a movie).
If it weren't for Daredevil's radioactive sense of sound, and his other superhuman senses and how they effect his motility, he would be crucified.
The Elektra film was a whole other dimension IMO.
