Take steroidsI think that the term " bulking up" has bad connotations, bc it really means nothing to just add mass.
Reducing or gaining mass without direction and competitive trainers and staff is always for bad. The team injury history that Garpax era Bulls had, indicates they were very incompetitive for professional team. You can add strength and muscle mass safely, when the plan is clear and it's all about functionality. The "bulking up" for me does refer to mindless pumping of iron.
