It is my belief that whatever you desire in this world becomes your master. When you want something, you go out and you work for it. I'd like to warn you to be careful of whom or what you serve. In the fitness world the majority of people want to lose weight and tone up, this often leads to an unhealthy obsession with the scale. In my experiences I've seen so many people check out mentally after not seeing the numbers move after a week or two and then they lose it completely. Do not let this happen to you.
The scale is only about 1/4 or 1/3 of the big picture when it comes to fitness. Other factors that you need to take into account are your body-fat, tape measurements, and for ladies depending on where you are in your menstrual cycle you can see an average gain of about 2 pounds due to bloat. These are all things you need to take into account to get an idea of what's really going on since weight loss is hardly ever linear.
Once upon a time, I had a guy come to me looking to lose weight. We trained for sometime and he more or less followed a generic meal plan I had given him. It looked like he had been making great progress when we decided to weigh-in one day. "What the hell, I've only lost 2 pounds!", a statement that sent me into panic mode being inexperienced at the time. Somehow through the confusion I remembered to do a body-fat test which revealed he had lost 10 pounds of fat and gained 8 pounds of lean mass since he started. He then told me that his clothes had been fitting a lot better that's why he was so confused by the scale.
So for those of you out there weighing in every day... Stop! Try weighing in once weekly and be mindful of body recomposition. 240 pounds may look different on Arnold Schwarzenegger in the 70's than it does on your plumber. Don't work for the scale, stay mentally checked in and make it work for you.
