Back on the issue of working out, it all depends on your goals. Different goals will have a different path to follow in terms of your workout regimen and nutrition. In addition, genetics plays a large role in how you develop.
Everyone has the ability to grow muscle but not everyone has the ability to be Mr. Olympia. Now that we have discussed this, I can provide some general advice on how to obtain the build that Chris has from his web pics.
In the gym, you want to be concerned with lighter weight and more reps. For example, your goal should be 12-15 reps on everything. Your technique should be a controlled movement to "feel" the weight. Using proper technique, one can make light weight feel heavy. Seeing someone control the weight is much more impressive than seeing the weight control them. Know what I mean? I recommend getting with a trainer to personalize your workout and to go over basic safety when weight lifting. I would say a minimum of 3 days per week in the gym in required and 4 is perfect. 5 days is simply too much. Also, start out with only a minuite rest in between sets and work up to only 30 seconds. Too much rest and your workout will be anaerobic. You want to be aerobic to rush that oxygen into your body and work on stamina.
Cardio, I recommend working up to the point where you can jog 3-4 miles 3 times a week, no more than 4.
Nutrition, Yes, you have to eat clean. This means knowing what to eat and when. That is not to say that one cannot schedule in a tasty snack once in a while. Again, talk with an expert to customize a plan for you.
Well, this is a brief and basic idea for someone who wants to be "fit". Everyone's skill, health, and metabolism level will not be the same so, what it takes for one individual might take something else for another. Good luck!
