If you are new to fitness, remember to aim for the right target. Unless you aspire to win bodybuilding competitions, huge muscle is not for you. Your body-image target should match your physique to start with, and be aimed to improve your chosen sport. Aim for fitness, a good appearance, with the strength and endurance you need to achieve your sporting goals. Then keep it up together with regular exercises. Weights by all means, running, and a sensible diet.

Oh, one more thing. Getting yourself photographed in a railway tunnel on an active rail line is maybe not such a good idea either!
