Look in order to run fast you need to have muscle.
But at some point too much muscle mass will inhibit you. Runners strengthen their leg muscles so they can faster. Now a huge hulking figure is going to slow you down due to flexibility. Those runners who bench press 250 certainlly dont look like the guys who bench press 750.
You certainly aren't very bendable when you have muscle in the way. This is why a body builder wont be outrunning a runner(though there's even more to that). The Hulk isn't going to be the most agile just because he has a lot of muscle. The guy can run really fast but agility is not about running fast. Its about being to alter yourself very quickly. Spiderman is very agile because of his flexibility and strength.
Just being strong does not mean you are agile. Especially since many heroes cheat.
The strength of a person's muscles has very little to do with how agile they are or how fast they move. Coordination, speed of nerve firing and the speed of muscle contraction are what matter. Take me for example. When I was young my reflexes were probably in the peak human category, my legs were very strong for my weight but in spite of that I was a mediocre runner and jumper because I had mostly slow twitch muscle fibers. My legs could generate great force but it was wasted energy. The Hulk shouldn't even be able to leap the way he does because that ability is not entirely determined by strength.
I disagree with this.The gasses expelled from a rocket are traveling at great velocity and it is that which generates the forces that propel the rocket. The Hulk's legs can generate great force but cannot do so at any greater speed than a normal man because he cannot move his limbs at a greater speed than a normal man.
Exactly.They are not, gymnasts or maybe even high divers are. Those sorta physiques match up to guys like Spidey or Daredevil more.
Taskmaster can temporarily increase his speed and agility by watching kung fu films in fast forward. No, I'm not making that up!
