With the advent of teen age a number of changes occur in an individual owing to changes in hormonal balance which marks this age. Teenagers are more concerned about their looks and their body physique. They are opting for various body building programs to keep their body healthy and fit. Some things should be kept in mind while joining any body building program to achieve maximum benefits out of it:

1. You should take a healthy diet while following any such program. A good diet is must for a good and healthy body. Body needs all the essential nutrients for its growth and development especially proteins, the body building nutrient which is required for repair and growth of tissues; and carbohydrates which is the richest source of energy.
   
2. Adequate amount of sleep is required for proper development of the body and mind. When you sleep, the body repairs all the damages done throughout the day and prepares you for the next day. Thus, for a program to be effective, proper sleep should be taken. A sleep of 8 hours is recommended for health growth of the body.
3. Before the age of 13, you should not go for heavy weight lifting programs, rather exercises which are low on impact like push-ups and chin-ups should be preferred. Heavy exercises should be taken up in the later years of life when the body has grown strong enough to take that much strain.
4. Strenuous exercises like squats and dead lifts should be done with great precision; else they will cause serious injuries to your body. You should start doing these exercises when you reach 16 years of age.
5. For any body building program to become successful, one most important thing is that should be regular in whatever you join. Do not miss out your exercise regime until it is really necessary.

Do not work out beyond the limits and follow the suggestions offered by the elders for efficient body building. Healthy body sets a stage for effective youth full of life in the years to come.
