I am 16 years of age and i am recently doing weight training. Many people tell me that its bad. Is it really bad? If so, why?

No studies have ever been shown that lifting weights stunts or inhibits growth. But, as with any exercise program if you do too much and you do it too soon, physical problems can occur no matter how old you are! The key thing is to make sure you have perfect technique with your exercises. Seek out the help of a qualified strength and conditioning specialist to make sure you don't develop any bad habits when you are just starting out.

Thanks and have fun!
