[Sunna]

Hello, my name is Mopster and I need to put on some weight!
I am 13 years old, 5'11 and 7.8stone. The problem is I need to put some weight on without becoming fat or unhealthy.
Any ideas?

are you tall and skinny ? if so you may have more fast twich fibers in your muscles than slow if so you will find it hard to gain muscle and you may find trying a fast twich sport /keep fit better suited to your body type like running tennis ect.
try weight lifting but it might be a hard slog .
good luck
let us know how you get on
