unsupervised bodybuilding for young teens is not recommended...before 15 years old i don't think a teen is mature enough to respect the rules of bodybuilding that include proper form and being cautious about accidents and gym manners to avoid injuries that could stunt growth or cause permanent damage.
Bodybuilding if done properly after 15 will not stunt growth, on the opposite it will lead to better growth, however it has to be supervised for a couple of years in order to ensure proper lifting habits and avoid bad form and bad habits.
it has to be done properly or else it could over time and repetition cause permanent damage to the vertebrates and to growth plates at the tip of the bones.
rule 1: AAS is not an option for teens , it will stunt growth and cause other damage
rule 2: proper form should always be respected, cheating is not allowed
rule 3: lifting heavy weights is not recommended because it will lead to bad form and to injury and it does not help a teen anyways. Repetitions and good form are crucial and will lead to a better and nicer physique later on after few years.
rule 4: patience is your best weapon, bodybuilding is a lifetime sport and life style, rushing into heavy weights at your teen years will not make you stronger later in life.....you will have time to catch up quicker once you had a solid basis and learned the good habits, and this takes years not days.... i am 51 and still learning!
rule 5: don't be dragged into showing off and injuring yourself for stupid reasons.
rule 6: good balanced natural diet and healthy diet, gaining weight should not and never be a concern...your concern is working out well, forget the stupid scale and concentrate on your workout with a proper healthy diet.
