[MCU] Are the Guardians of the Galaxy superhumanly strong and durable?

EDIT:  They appear to do some pretty fantastic things - powerful leaps, lifting apparently heavy objects, soaking massive impacts with no visible effects, etc.

But is this due to them being tougher than a human or is it due to technological enhancement, being on low-gravity worlds, etc.?  I seriously can't tell.

Personal shield emitters and flexible body armor is standard equipment for galactic adventurers.  Starlord's average quality Ravager coat alone provides substantially better protection than you might expect, and his gear under that is designed to cushion his body on impact and retain heat within the vacuum of space.  Just because it looks like he's wearing nothing more protective than a leather coat doesn't mean he's actually going out there in one.  Don't underestimate Gamorra or Rocket's numerous cybernetic implants and what those can do to improve their strength and hardiness either.
