Don't forget to breathe. By holding your breath during even a single repetition of an exercise, you are depriving your body of valuable oxygen and experiencing muscle fatigue much sooner.

Muscle Isolation. Try to isolate muscles when you are working out. Most exercises rely on secondary muscle groups. For example on pull downs for back, arms can tire before your lats do because they are much smaller muscles than your back. By concentrating on using lats to pull weight down you are effectively reducing work your arms are doing and placing workout on lats.

Each exercise that you may be doing may also have specific areas where bad form may result. There are many examples. If you are doing any type of chest press while lying flat on a bench make sure your lower back is flat on bench. Many people forget about this and end up curving their lower back without even realizing this and risking chance of a back injury. This is also true if you are sitting up for certain exercises or sitting on a bench with a vertical cushion. There is a tendency to slouch. Make sure you sit up straight and suck in your abs to keep your back straight. Other exercises require that you keep your knees slightly bent.

As a matter of fact, in every day life you should also be paying attention to how you lift things, sit, etc... This way you will avoid any nagging pains or aches. These body pains exist to tell you something is being done wrong to your body. You will also improve your posture.

Over time you may want to modify a certain exercise. Add some variations to more effectively or differently work your muscles.

These are just some of most important points to pay attention to when weight training. By paying attention to these points you will avoid any possible injuries and you will maximize potential from every single workout. And this is whole purpose of weight training. To strengthen your muscles, prevent injuries and know that a little attention to your health now will go a long way to your future well-being.

Obesity has become a nationwide epidemic. Regular activity, along with a nutritious diet, that incorporates portion control is key to maintaining a healthy weight. Public and private sectors need to band together to encourage more activity. Walking programs for schools, worksites and local community are some examples. The most important change has to come from individual and families. Every person must realize benefits of physical activity for mind and body. Then commit to a lifestyle that is active for whole family.
