Honestly? I love bodybuilding. I'd love to look like a professional bodybuilder. Right now I spend roughly an hour to an hour-and-a-half at the gym, 6 days per week.
- Monday: Quads
- Tuesday: Shoulders
- Wednesday: Back / Abs
- Thursday: Hamstrings / Calves
- Friday: Chest
- Saturday: Arms
The hardest part, by far, is dieting properly. Eating enough protein consistently every day, and keeping carbs at a manageable level depending on existing goals (losing weight or bulking up). Also: consistently eating clean is quite hard -- it requires a lot of sacrifice: less meals out with the wife, less 'typical' foods, and it frequently makes going out with buddies for late night activities hard.
I've been doing this consistently for the past 2 years, and have been seeing great results though. Overall, I really enjoy it.
