So you've finally decided to get off the couch and drag your out-of-shape body into a local gym. That's a great first step, and undoubtedly the hardest part of many journeys is the beginning and actually getting it started.
There is a danger involved in the gung-ho attitudes of many virgin fitness buffs or those newly awakened from a bout of fitness hibernation though, and that is that their goals are often too lofty and they expect to achieve them too soon.
It's not a surprise really; people are usually bursting at the seams with motivation when they make that decision to engage in fitness, and that is often fuelled by a very specific desire or because they've finally reached the breaking point and said "enough is enough".
While in general it's probably preferable to be overly ambitious rather than the alternative, having unrealistic goals and expectations in fitness is often extremely detrimental. When people don't immediately reach their goals or see the changes they expected, they inevitably get discouraged, and that can lead to them giving up on fitness.
