It is often thought that exercising at lower intensities such as walking, burns more fat than at higher intensities (e.g. running). The science behind it is true in so much as when we work at lower intensities we require less 'quick release' energy (in the form of carbohydrates) therefore our body utilises a higher fat-to-carbohydrate ratio.
In order to lose weight you need to burn more calories than your body consumes and uses every day. In other words you need to be in calorie deficit. When we walk instead of run for instance, we burn fewer calories in the same amount of time the exercise is performed. More precisely, if you burn 250 calories everyday from a short fast jog, you'll see a bigger difference in weight and fat loss than if you walked everyday for the same amount of time. There is a higher percentage of fat being used during the walk but overall a lower total of fat is lost.
Intensity is the key here. The more effort you put in, the higher your heart rate therefore the more calories you burn. If you go to the gym and spend an hour chatting to your mate on the cross-trainer next to you, you're not working hard enough!

I often wonder why some individuals are highly motivated and constantly strive for success, while others seem to lack motivation, avoiding evaluation and competition.
Motivation is defined as the direction and intensity of one's effort. The direction of effort refers to whether an individual seeks out, approaches, or is attracted to certain situations. Intensity of effort refers to how much effort a person exerts for any given situation. For most people, direction and intensity of effort are positively correlated.
If an individual wants to achieve their desired levels of fitness, they may need to get 'more motivated'. As a Personal Trainer I help individuals in this pursuit by setting goals and helping them work harder toward achieving those goals. My belief is that motivation results from an interaction between personality traits, needs, interests and situational factors such as coaching style and environment.
Long-term goals are important but short-term goals are crucial to performance improvement. The key to improving health and fitness is to develop a progression of short-term goals that lead to a long-term objective.
Monday mornings can be a mixed bag. We may feel highly motivated at the start of the week or we may feel lethargic and unenthused. Think about those short-term goals. What do you want to achieve in the next seven days? How good will you feel by the end of the week if you've had some good quality workouts? How will a productive week of training progress you towards that ultimate goal?
I often remind my circuit training class on a Monday night what a great start they've made to their week. Clients seen on a Monday end their session feeling really positive about the week ahead. A Monday workout is the most important workout of the week. Make it a good one.

The training principle known as Specificity is a simple concept. For any given goal, you need to be specific in your training i.e. to be a good runner you must run! If your goal is a triathlon you would obviously incorporate all three disciplines into your training schedule.
The Specificity principle can be applied to many aspects of your training. For instance, your individual fitness level. You should only train to your own capability. 'Overloading' too often or too much can result in injury or over-training syndrome.
Personal training sessions are often designed with specificity in mind. Coming to a Personal Trainer with the goal of Triathlon in your sights means sessions will focus on strengthening the specific muscle groups that are needed for that particular sport and attention paid to cardiovascular stamina and endurance.
Although specificity is important, it is also necessary in every schedule to include exercises of a general nature. These exercises may not relate too closely to the movement of any athletic event but they do give a balanced development and provide a strong base upon which highly specific exercise can be built.
