When should we work out

We should start has a teen.in the following writing below.

First I would be easier on the body if you make a mistake it will make easier to recover.its like a new car it will take less damage to the cars frame.That will give you time to learn your form.

Second of all it will be easier to learn a routine and implement it to your daily routine. 

Last of all it would be mature muscle looks better than muscle that has been recently grown.

This why I would start has teen.the choice is upto you what you do.
