I run 20-25 mins before going to the gym. After gym just walk home 5 mins.
Play soccer once a week.
To give you an idea of my strength I can press bench ~190 lbs, I can do 4 series of 10 reps pullups, lift 145 on Machine Preacher Curls, I do 50 Cable tricp extension, Shoulder press 100lbs.
 
If I do many isolation excersices for a muscle, wont it get bigger? Or is it better to do the (i dont know the correct term) biggest part of the muscle exersice?

If your in the Gym more than an hour you are doing to much...IMO
