You need to establish a plan of attack for your training program. Just going to the gym and just doing what you see others doing is not a good option if you want to see results. Unless you know precisely what you are going to do to get your self in shape, you are most likely to start messing around, missing workouts or even worse giving up.
An excellent way is to buy an exercise video, this way, all the planning and exercise routines have been done for you. Fitness DVD's are a great option because they give you a training program that you can easily follow to get your desired results but since you are able to use them practically anywhere, they will fit in with your lifestyle.
If you devise a fitness program for yourself, you still need to make sure that it is complimentary to your lifestyle, this way you are more likely to continue with it. A good example is always to take into mind your work schedule so you are able to exercise without it encroaching on other aspects of your life.
Most exercise video creators know the secret to results is consistency.They all push the idea of making working out as convenient as possible because if exercising becomes too hard to maintain, it is unlikely that you will continue to do it for any length of time. While you might like to have a gym membership and workout for two hours every day, that might not be possible with your other commitments and rather than doing nothing at all you can still benefit from something more convenient that you can do regularly.
Expert instruction is also very helpful and that is why I love the idea of purchasing an exercise video. You are able to get advice from some of the best exercise instructors to help you get to your desired fitnesss or fat loss goals.
The best advice I can give is that in order to get the best out of your exercise, whether it is walking or lifting weights it is a good idea to record your progress. Mark down each time you trained and what results you achieved from it. Record & time your walks to find out if you can do the same walk in less time or walk further in the same time. Record how much weight you are lifting and how many repetitions you are completing, and then over time see if you can better those marks when you return.
Constant improvement no matter how small can lead to major changes over the course of a year.
