Okay,
From reading your question,
I do not advise you getting a bulldog, because these dogs aren’t very athletic, (maybe an American Bulldog)
A pitbull, oh I love these big babies!
Not a dog like them, but most people say these are vicious dogs, and they are mean. Not true, it’s all in the breeder. It is very hard to find a breeder who has a very clear background for the dog’s history, even if the grandparents of the puppy, was in dog fights, that will still affect you pitbull. I’m not saying that there isn’t a good breeder, but it is hard to find one. I speak from experience. If you think you can find a responsible pitbull breeder, then sure go ahead and go for one!
But I would also like to cross your mind with another breed (also one of my favorites) a Boxer!
Not sure if you have looked into this breed, but you should. They somewhat have the appearance of a pitbull, just taller.
Boxers on the other hand, you can find a good breeder a lot more easily than a pitbull.
Here is just some quick information of the breed.

Character: The Boxer is happy, friendly, intelligent, attentive, and loyal. Boxers develop strong, close bonds with family. They have lots of energy and a serious demeanor, though they can be clownish and playful as well. They make excellent guardians and companions.

Temperament: The Boxer gets along especially well with children. They also get along well with other dogs and household pets, but may be aggressive towards unknown dogs. (which should not be a problem if you socialize as a puppy… which is a great experience)

Training: The Boxer must be trained not to jump up at people as it is naturally fond of jumping. (Quick learner) The Boxer is ideal for various sporting activities because it can be highly trained and learns very quickly. Boxers may be stubborn in learning, but they are responsive to commands.

Activity: The Boxer needs plenty of physical and mental exercise on a daily basis. They should be allowed to run or go for long walks regularly. Boxers enjoy playing fetch or other activities. They can tolerate apartment life if exercised sufficiently, but a fair-sized yard is ideal. Lonely, inactive Boxers can become stressed out and destructive. (Since you are planned to give your dog a lot of exercise, you should have no problems!
