I was around the whole bodybuilding explosion when I was in high school and college. I have known so many guys that have thrown away there future chasing the dream. Everything revolved around the gym and getting money to buy bodybuilding drugs out of the trunk of a car in the gym parking lot. These guys put bodybuilding first instead of their future. Future career and education toward a career took a back seat. Then due to finances, health, or criminal arrest they stopped juicing in their 30's and realized they had nothing. A lot of them look like crap now. One even said that lifting without steroids is a waste of time.
I understand if a guy wants to compete. I also understand if a guy now trains for other goals like real fitness as they get older. One thing is for sure. Never stop training.
