You look like a body builder during the bulking season
You have lots of muscle mass, but you're lacking the "definition" of muscles?
Definition typically comes from your cutting season depending on when you do it because you're going to be cutting weight and getting rid of all the excess weight that isn't necessarily "muscle". Thus, once you do this you will have a better opportunity to define. Lower body fat is going to give you the opportunity to have the definition you desire.
gain fat, lose definition
lose fat, improve definition
So maybe improve your diet to be a bit healthier and if you're not already increase the amount of cardio in your workouts.
Personally I love sprinting that shit cuts you up and also gives killer abs.
