Should teenagers be build muscle

Answer 1

yes you should try and healthly build muscle but dont push yourself to hard as it can stunt growth press ups and sit ups are good for exercise and muscle building as you are using your own weight and not using to much weight and straining yourself

Answer 2

This is kind of complicated. In the earlier years of adolescence, your body is still changing, A LOT. It is possible that extreme athletic activity like lifting heavy weights can interrupt that natural muscle development, even to the point of possibly preventing you from hitting that two-inch growth spurt you genetically may have coming. Staying fit and active is important, but consult your doctor before starting an intense weight training program to make sure your body is developed enough to take on such consistent, strenuous activity.

Also, it is incredibly important that you learn how to lift weights properly. Many people, regardless of their age, go into a weight room and lift with poor form in order to push more weight. Lifting with bad form will prevent you from gaining all the strength and physique goals you want, and may very well result in injury. Get someone to show you how to use all the machines or free weights the right way, and allow yourself to naturally progress in strength.
